microcontrollers

[fast wagon]

i see

so then i should only use it for stripping and get a seperate cutter

or should i use this one for cutting and get a separate stripper

[indigo plover]

Just get whatever you want for a stipper and don't use it as a cutter, then get a cutter on the side for cutting

Whether there is a cutting or plying part on the stripper doesn't matter. Just use it as a stripper

[fast wagon]

also what is bedding

[indigo plover]

Pliers

Bending or bedding?

[fast wagon]

bedding

last time you said bedding

^

[indigo plover]

typo : bending

[fast wagon]

oh i see

so pliers are simply just used for bending the wire

[indigo plover]

Yes

You need to do 90 degree bends on leads everytime you want to plug something somewhere and you don't want it to move

[fast wagon]

my bad if this is a dumb question, but isn't that something that can be done with hands

this is good right
https://www.amazon.com/Beadsmith-Jewelry-Round-Pliers-PL513/dp/B000SNBC74

[indigo plover]

Yes, if you have nails and you bend parts in advance... before plugging them into a breadboard. Once they are plugged in and you need a specific bend, measuring with a plier and bending it is non negotiable

[indigo plover]

Yes

[fast wagon]

bet

[indigo plover]

Oh

No

The inside has to be flat

[fast wagon]

oh

[fast wagon]

how about this
https://www.amazon.com/vouiu-Needle-Pliers-Jewelry-Making/dp/B08FRP8QGX/ref=sr_1_1_sspa?crid=2B4PLW5L0SBFL&dib=eyJ2IjoiMSJ9.-v6sS5eu0kI8SjYg3mzKdRU8o4o038O_N5oXQhOIjwpeTBFUbLDglnyDDtR3Yj_RfEEz9VdOpqhXPyCbHkxWiIprKbn1c8ZVExRZ-43YbPEbQCadgOfjIUHxeJM_9V5SiNFWJUVTlg38e8KOYw1hQcme7P_EgpEmrzzih3gu45hJuOg5t1S8hquscbSv0NWWRCVOPuZcI4mmB47AVb0cgc0ulT-VGqPjdM-XpAjcvCO2Jn9HVNyijPb85QKxVxHIa3YyTRNcocqMy2KUiGGIbqWbMGHprKL-6qWH4hjrxMc.kvz4OykqpyJn6kVkW37SMBslVPYY_TyXaC1l3JJDvo4&dib_tag=se&keywords=pliers+for+wires+bending&qid=1742529858&s=arts-crafts&sprefix=pliers+for+wires+bending%2Carts-crafts%2C167&sr=1-1-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&psc=1

far too many ones that say jewlery making and not enough that say wire bending lmao

i guess that doesn't matter much though right

as long as it's flat on the inside like you said

[indigo plover]

better

[fast wagon]

there's no issues with this right

even if the edges are pointed

[indigo plover]

Those are preferable

Also, pointy is relative

Those are quite round edges

[fast wagon]

also do i need resistors

[indigo plover]

Probably

[fast wagon]

ah shit i didn't know about that until today someone told me

[indigo plover]

Depending on what exactly you need, you could get one of those 40$ resistor kits off of digikey

[fast wagon]

i know nothing about this stuff lol

[fast wagon]

yo sorry to bother you again, can you tell me a list of everything i'll need to get started?

i actually have no clue about any of this

[main nexus]

Hello - I am looking for a Python based microcontroller that is fully assembled ( no exposed components ) that is easy to program and can boot and run Python programs? any help with companies, projects would be greatly appreciated, thanks

[elfin sphinx]

a raspberry pi zero 2 W. Its not a microcontroller precissely , its like a small computer. but it can run python as is and has plenty of GPIO pins for you to interface with other elctronics. and with a 2 buck case ,you can have no exposed componenets. and its pretty powerful as a "microcontroller".

a "microcontroller" like arduino/esp32 cant run python as it has less resources and python needs ALOT of resources to run.

[fast wagon]

hey, i'm using an arduino with the vs code platformio extension in wsl, i connected the usb to wsl so that the port can be added, but now i'm having this issue when i try to upload the program to the arduino

[elfin sphinx]

why are you using WSL ?

programmer not responding can happen because of tons of reasons

basically means the communication between your PC and the arduino board's programming chip is not happening

[dusty dock]

My New program

[fast wagon]

i've been using wsl for everything in programming so i started using it for this too

so basically connecting the usb is not enough it seems

perhaps does it require dual booting?

[elfin sphinx]

you are inserting random things in a dead simple environment.

scrap wsl , you dont need it at all

firstly , check if your arduino board is shown up in the COM port llist in the device manager

[fast wagon]

yeah it does

so then do i have to reinstall vs code and go through all the platformio setup in windows?

or is there any way to run it in windows from vs code which is run in wsl

[elfin sphinx]

there should be some way to do it

i have never done it myself , so i have no idea about what your setup looks like with the WSL

i would just remove WSL from equation altogether and try with plain vscode + platformio

[fast wagon]

well the terminal that runs in vs code itself runs on wsl cause it's been configured as such

so to remove wsl from the equation it would be like changing the os itself

[elfin sphinx]

you can just open a new terminal instance thats not wsl , its just 1 button click away.

[elfin sphinx]

im not sure how you come to that conclusion

WSL is like a "service" in a way. so its upto you if you want to use it. it doesnt come in your way if you dont want to use it

as you can see , i have both , a regular terminal and a wsl instance open in the vscode side bby side

why do you think you are using wsl anyway ?

because all the commands of platformio that you run via buttons run in regular terminal , not via WSL

[fast wagon]

i started using wsl cause a few students from the uni i'll be going to suggested that i do so cause of c++ compiler working with linux

[elfin sphinx]

although wsl is a great and very useful thing to learn,

C++ compilers work just fine on windows , macos or lilnux
you absolutely dont have to use WSL to work with them. i got through uni (and still use) windows for almost everything

[fast wagon]

i see

but i can keep all my files in the wsl file system and then just run all the arduino stuff on a windows instance of the terminal right?

[dreamy wasp]

Can someone plz find be a 4 or 8 bit shift register circuit (no ICs) diagram and/or a picture of one

[fast wagon]

yo how did you do this by the way

i can't find how to do it anywhere when i try searching it up

[fast wagon]

if i'm using arduino uno r4 minima, should i select that or just arduino uno in platformio

[fast wagon]

nevermind gang, i got it

holy shit finally

now i can get started on the embedded systems grind

nevermind i lost it

i have no clue as to what just happened

[elfin sphinx]

sure, i dont see why not

but when developing stuff for embedded , you usually write some code , immediately upload and test it
so constantly switching between the two things could be a little bothering

[elfin sphinx]

in the top right corner , where i have highlighted the cmd , you should see a dropdown arrow next to the + button, if you click on the arrow , you can choose which terminal instance you want to open

[elfin sphinx]

when selecting board, selecting the correct one you have really matters because of different boards have different processors, uploading tools , pin definitions etc

if you are not sure wwhich one you should choose ,you can read the board selection wiki of platformio

[elfin sphinx]

selecting the wrong board probably messed up your stuff

[elfin sphinx]

@fast wagon if you are new to embedded dev , just use the arduino IDE , learn how programming a board works , get your basics done. then move on to better tools like platformio

[dreamy wasp]

Ty

[fast wagon]

yeah probably, but when i switched to the right one, what happened was it kept detaching and reattaching (not physically, i mean the system did that)

so then it wouldn't work cause when it detaches it goes back to windows (disconnects from wsl)

but after the first time i shared it, it still always stays shared and i'm just having to connect it each time

but this one time, i have no idea what happened but the usb also unshared some how, then when i reshared and reconnected, the upload worked

then when i tried again, it went right back to the same issue of detaching and reattaching

so i'm not sure how it worked that one time, but i know it has something to do with what cause the usb to somehow be unshared that one time

but now i know to fix the issue i have to find a way to prevent the usb from detaching, that part i don't know how to do though

[fast wagon]

i don't have any powershell option

or cmd prompt option

the options are bash, tmux, and js debug terminal (i have no clue why it's specific to js, i have never done anything with js)

[elfin sphinx]

at this point , its best to get to know more about your set up , your board, your code , your circuit diagram etc

[elfin sphinx]

pretty sure there is some way to add more entries in the settings somewhere

[regal mortar]

Any good cheap led strip that is easy to use with Arduino or esp32? I'm under a budget of 500 rupees (6$) . (It only has to display one color no matter what the brightness is)

Easy to use cause I suck at connecting wires

[elfin sphinx]

how long do you need the strip to be ?

arduino / ESP32 have very limited power , so they will not be able to power any LED strip directly

[regal mortar]

2 meters

[elfin sphinx]

and you want to control its brightness with arduino ? or what do you want to do to it with arduino ?

[regal mortar]

I'm using a motion sensor and I want it to turn on when it's detected.

Kind of simple but I don't have much experience

[elfin sphinx]

buy any generic 12V LED strip that you like. Buy a 12 V Relay module , connect it to an ardino and done

you can control the LED strip with arduino

(The LED strip WILL require a 12V power supply)

here is a 12V 5m LED strip as an example

you can probably fit a relay module and a 12v power supply in your budget

[regal mortar]

Ohk thanks I get the outline of the idea but I don't have much experience in Arduino so how do I connect the relay is there any videos regarding that can guide me?

[quaint nacelle]

Here's a video that I just skimmed that seems plausible https://www.youtube.com/watch?v=VFzeFEPreC8

[regal mortar]

Thankss

[reef ember]

I just realized how bad the nintendo switch 2 is I want to get a handheld so I will most likely buy a steam deck of make my own

if I where to make my own hand held what micro controller should I use

[quaint nacelle]

How 'own' do you want it to be? A lot of people build projects like that around the guts of what are basically Android phones, and that can save a lot of steps if it's suitable. Custom stuff might be more fun to build of course.

[reef ember]

I want a handheld that can run stuff like videos and play 1080p low settings. I have a idea of making it so I can add joycons or a external mouse and keyboard or I could add a controller. I have a 3D printer so it would be pretty easy to make the shell but I basically need something with a lot of ports

[elfin sphinx]

A steam deck is a pretty powerful device, it's basically a pc. If u were to make your own, you can choose a board from the lattepamda alpha series, depending on how much performance you want. There is a youtuber called greatscott who has done this exact thing that u r talking about, u can check him out if u want

[fast wagon]

if i'm using wsl is there any way to permanently bind a port to wsl so that if it detaches or i take the usb out, it will still be connected to wsl when it reattaches

this is what claude said i should do, just want to make sure this is alright cause blindly following llms is probably not a good idea

run this in powershell:

$deviceId = "(Arduino device ID from usbipd list)"

usbipd bind --busid $deviceId --auto-attach```

run this in ubuntu (command prompt with wsl distribution)

SUBSYSTEM=="tty", ATTRS{idVendor}=="2341", ATTRS{idProduct}=="0043", SYMLINK+="arduino", MODE="0666"```

[quaint nacelle]

Hmm, looking at this, it seems like you'd want also --wsl? https://learn.microsoft.com/en-us/windows/wsl/connect-usb

[fast wagon]

oh yeah

i rely too much on claude for system configurations lol

[quaint nacelle]

It's usually really helpful for at least pointing you in the right direction though

[fast wagon]

--auto-attach wasn't working so i told it that and then it gave me a solution that worked

[fast wagon]

yeah true

but if i'm completely relying on it the way i just did then what's the difference between me and a vibe coder lol

[fast wagon]

since this was the only issue i had no matter which ide i used, i decided to go back to platformio and deleted arduino ide

just want to make sure, just directly doing sudo rm -rf arduino-ide_2.3.5_Linux_64bit.AppImage is fine right

or is there any other uninstallation process

i probably should have asked this before doing it

[quaint nacelle]

Yeah I believe for AppImage stuff you can just remove the file and you're done

[cloud hinge]

For pydroid is there a way to interface pydroid with pybluez to attach mac address or something similar to connect from android pydroid to esp32 with pyserial. I would like to use pygame to connect to all this and be able to recieve esp32 data into pygame. If we could get it to work then I think pygame on pydroid would be an excellent way to interface with esp32. I guess with a wire it's possible but wireless would be idea

[spiral sandal]

with wifi i guess telemetrix would work

old android don't expose serial it is quite recent

and bluetooth would need an api in pydroid i guess

[cloud hinge]

Nice, that's a good work around. Bluetooth is champ in less delay and super easy to work with pygame. I'll have to look into how pygame can be used with wifi. Great idea and I'll look into it. Much apprecieted!

[cloud hinge]

Good to know

[spiral sandal]

lot of serial port require drivers that are only in newer linux kernels

and vendors may not ship them on device

hid usually work but it is low speed

[cloud hinge]

Bluetooth also has only a 5 to 20 nano second delay. To be able to do all that on the android pygame would be priceless

[spiral sandal]

i use https://github.com/ArminJo/Arduino-BlueDisplay and/or https://github.com/MrYsLab/telemetrix-aio

telemetrix works with pygbag/webview too ( so pygame-ce )

but wifi has more latency

[cloud hinge]

I'll probably try this out, thanks for the links. Telematrix looks a bit complicated but maybe i can figure it out. Edit update. I may have found a way to use bt another way with pydroid3, if I do would u be interested? It looks pretty straight forward and I'll try and test later

[spiral sandal]

if same code can work in a webview+bt api yeah that would be really great

[lyric vigil]

will bluetooth keep working even if you lightsleep()
esp32

[elfin sphinx]

no
te only things active during light sleep are RTC , ULP coprocessor

[lyric vigil]

what about after wakeup?

[elfin sphinx]

after proper wake up , the ESP32 will behave normal meaning all the stuff will be active

although youy might need to "reconnect" to the device you were previously connected to

[lyric vigil]

i think ill test it

[elfin sphinx]

you should read up the documentation about power saving modes to understand all the details

[lyric vigil]

noted, thank you

[solemn robin]

Hellow

[pseudo sinew]

You can get a Mini Desktop/PC. You can power it off of a Portable Battery if you get one that only needs like 65 Watts of Power. Then the rest is getting a small screen and hook everything up and you should be good to go. Mini PCs costs a lot cheaper than steam decks or handhelds computers. I kinda built a mini PC gauntlet thingy like in the Sci-Fi movies which looks cool and runs Linux. You'll be surprised by how much Windows eats up your battery and/or how much Linux saves your battery. Then if you want to add pins to your mini desktop to make it like a Raspberry Pi, just plug in an ESP32 and you are good to go.

[elfin sphinx]

How is this handheld lol

[pseudo sinew]

You can make it handheld. Might not be that light but not that heavy either depending on how you go about to make it.

[elfin sphinx]

what you are describing is just a laptop. A full computer powered by battery and got a display xd.

laptops arent exactly "handheld".

and the cost / trouble of making them handheld is just too much compared to buying a ready board like lattepanda

or just buy a small laptop and call it a day

[pseudo sinew]

Laptops are BIGGER and also needs more power than Mini PCs. At least the ones I looked at. Have you never seen a mini gaming PC before? Also, a lot of Laptops can't be upgraded or they are just too big. Mini PCs are small and can be upgraded as well as running on lower power and are just as strong if not stronger. Laptops aren't exactly handheld, hence the name "laptops", implying on the lap. But Mini PCs can be made to be held if you know what you are doing. I made one on my arm/wrist like in the Sci-Fi movies. Of course, I used a smaller keyboard for it and a touchpad mouse.
The cost of LattePanda is too much. I recommend looking on Amazon for Mini PCs and then you'll find that Mini PCs are a lot cheaper than LattePandas.

[elfin sphinx]

I think your definition of handheld is that " can be held in hand regardless of if it is comfortable or not". My definition of handheld is " like a steamdeck/game console, should be comfortable ". And the laptop was clearly a sarcastic comment.

if you have good mini PC recommendations , feel free to send links. i am not totally opposed to the idea of it , but all i have seen are either bulky or expensive for a handheld

[pseudo sinew]

My definition of a handheld is something that can be held on the hand. Tablets are considered handheld in my definition. They are okay to be held on the hand.

You didn't bother to check for yourself on Amazon so I did your job for you. The first few mini desktop computers on Amazon were small and cheap(Under 500 USD and VS their Laptop versions).
https://www.amazon.com/Micro-Mini-PC-Computers-N5105/dp/B09Q8Z6VB7
https://www.amazon.com/Desktop-Pentium-Display-Compact-Education/dp/B0DZP66CR8
https://www.amazon.com/KAMRUI-Windows-Desktop-Computer-Ethernet/dp/B099KSJN8P

There are more expensive ones with better specs and more power.
https://www.amazon.com/GMKtec-4-90Ghz-Desktop-Computer-Windows/dp/B0DCVTQ9CL
https://www.amazon.com/KAMRUI-Processor-Windows-Computer-Business/dp/B0C1M822S2
https://www.amazon.com/Beelink-SER5-Graphics-Computer-Support/dp/B0C2P486GQ/

For the price range, they beat Steam Decks. Steam Decks are not worth it in my opinion. They are weaker and can't run Windows well, if at all. These Mini PCs can run Windows very well. Although the one I have I ran Linux on it since it uses less power. Also it's literally on my arm, and pretty comfortable. You never seen a Sci-Fi device like in the movies where they have something strapped on their arm and some computer stuff they tap on???

To make it even better, you can upgrade your mini-PC specs unlike Steam Decks.

[elfin sphinx]

500 USD is cheap ? 😂

he just wants something that can play some 1080p videos and games , he aint trynna create steamdeck lol.

if steamdeck is worth it or not , is your opinion which is pretty irrelevent to the question OP is asking.

i did do my research and as i said in my previous message, they are either bulky or expensive for a handheld device that needs to play some video and some games.

also with your definiton of "handheld" , even small laptops are handheld since they can be held on your hand.

you have to understand that OP wants to make it handheld , which means it needs to have a battery (and in turn means that the actual device needs to consume little power) , a display . Good luck fitting all that in a "handheld" space.

is it possible to fit all that with the mini PC you mentioned ?maybe. will it be handheld after all that ? i highly doubt it.

the sheer thickness of these things is crazy

really not sure where you are getting the idea of competeing against a steamdeck

[vernal schooner]

Hello anyone can help with pic microcontroller but assembly code? I need help with a debug. Thanks

Do I post my question on stackoverflow nd send here?

[indigo plover]

What's the question and which PIC is it?

[autumn stratus]

Hey Guys,
I'm new here and wanted help with a project im working on. I have a custom i2c PCA which houses 9 vl53l3cx, time of flight sensors and a tca9548a. I needed some help with my code.

The problem im having is that the readings from my sensors are very inconsistent.

Here's the code im running

[hasty zealot]

[mental jungle]

what books do you recommend that teach how to apply electronics concepts into practice? I've done a foundation year (prerequisite year before going into a degree course if you do not have the necessary A level/GPA grades to get in) so I know the basics already but they barely taught how to apply it

[indigo plover]

Define the "basics" you speak of. We'll move from there

[fresh jungle]

Anyone know where to find the mediatek vcom usb drivers? Every site i go to is a roulette on whether or not I get malware and not even chatgpt knows what to put its money on

[quaint nacelle]

It sounds like this is for connecting an Android device to Windows?

I mean there's, wow: https://github.com/muojie/spec_mtk/tree/master/MTK_driver/Tool/Driver - USB VCOM Driver (binary)/Win7

Or https://github.com/evadne/gemini-notes/tree/master/Windows_10_MTK_VCOM_USB_Preloader_Drivers oof

Yeah this is a sketchy bunch of hits, you're right. This must come with some SDK with a wildly different name maybe?

Some of these hits are obvious malware sites, yikes.

[elfin sphinx]

you learn practical stuff by doing practical stuff , not by reading books

[mental jungle]

I know that. I’ve already got a few simple projects that I want to make. Just want some books thatll help me better understand how to apply the theory into practice. For now, Ill be using a simulator (tinkercad) to construct my projects but even if I can buy a physical kit, I want to make sure I do things correctly so I dont end up damaging my components.

[indigo plover]

You mentioned basics. To me, the basics include the Laplace transform. Depending on your current knowledge, I'll provide a book reference, either specialised or general

[mental jungle]

Then I guess Ive got more 'basics' to learn. I am in uni atm but Ill be starting my 1st year next year (sept2025). The foundation year only taught us the more elementary basics (e.g. rectification, smoothing capacitors, sensor basics). Currently, just doing notes for the rest of semester 2 before I go onto applying the knowledge

[vernal schooner]

Got the question solved but still thanks

[indigo plover]

Have you done op-amps? Transistors? Have you seen decoupling? Logic circuits?

[mental jungle]

Done op amps but not logic circuits. Assuming youre not from the UK, when you take a foundation year in university, it only teaches the bare basics you need to be able to understand the content when you get on to the actual degree. A foundation year assumes students do not have the necessary knowledge required to be on the course; in this case, because I’ve always done a biology based degree but I’ve switched to doing an engineering degree, I need to do a foundation year that teaches the basics (i.e. high school - entry level uni) of mathematics, mechanics and electronics. Hope that clears that up

[indigo plover]

You could try your hand at making an amplifier and a small synthesiser to experiment with. It's a lot of fun and makes for good practical experience.

This book is good at starting you off : https://www.amazon.ca/Make-Analog-Synthesizers-Electronic-Synth-DIY/dp/1449345220

With your level, this is as much as I could recommend. There is a good challenge in here and it is a big learning opportunity

[fresh jungle]

Thats what im saying, if i manage to find it tomorrow imma see if I can get permission to put it on github to help the next poor soul who has to dig for it. Chatgpts word is it comes with SP flash tools but that one has about 10 clone sites with little indication of which one is the right one

The original "trusted source" redirects to a site with seemingly no download link save for those start now buttons that are conveniently placed ads

[fresh jungle]

Think i found it, will verify tomorrow

[mental jungle]

Thank you. Ive been reading art of electronics as so many people have been recommending it. It doesnt seem as complicated as other people say it is but then again my maths ability is pretty strong which helps

[fresh jungle]

Verified, it works

However i made an oopsie in my next to zero experience with low level programming in command line tools and failed to realize that the e in the command i ran was a prefix for erase

The metadata partition is now gone

[quaint nacelle]

Anybody ever written anything for a Cortex-M0? They seem to be everywhere now.

Just curious how 'fun' of a language you used, if it wasn't C etc.

[indigo plover]

By "fun", is implied which company makes the part. The experience can be great; it can be tedious

[bitter swallow]

I'll be using ESP8266, I want to know if it's codeable through python, and has a wifi module? I want to make a web interface along with it

[elfin sphinx]

it does have wifi capabilities.

It doesnt s upport the regular python though.

it supports micropython , which is a python based langauge meant for microcontrollers

How are you bro?

[errant wigeon]

Please stick to the channel topics.

[mental jungle]

is there any software or website than can help verify if my circuit calculations are correct or is it a case of trial and error? I am using tikercad atm to simulate all my circuits (once I get a bit of additional income, ill buy the physical components)

[indigo plover]

Falstad

Ltspice

Search for "electronic circuit simulation"

[mental jungle]

im fucking struggling in applying the thoery into practice. Ive used breadboard in my foundation year but tbh i learnt nothing. literally it was just do this and do that. Im trying to follow a basic circuit and struggling to assemble that

[glacial stone]

i feel ya, learning electronics is hard for me, everybody be like "ohm's law ez"

but need a more intuitive understanding

[mental jungle]

also I dont just want to be following a tutorial, I want to learn why each component contributes to the circuit. Ill follow a few tutoorials on tinkercad so I can learn how to actually use the breadborad and start off from there.

[willow star]

https://www.build-electronic-circuits.com/basic-electronics/
This website has helped me quite a lot when I was starting out, I feel like it explained stuff pretty well. It's probably good to refresh the basics if they weren't taught well

[hallow igloo]

Ok sir

[ruby osprey]

Hey, anyone know any P N junction transistor which flow charge when a small 🤏 current incounter? Why? I have a unusable phone so I make a app which turn the flash light 💡 of phone on voice command and connect two ✌ wires on flash light of phone , which just work like a switch to turn on any big Ac appliance, if found any transistor which can work like switch give little take more 👍

[indigo plover]

Physics works in mysterious yet well understood ways. It's a bit like English in that regard

[spiral sandal]

don't use wires keep complete electric separation , use a LDR instead of potentiometer in the classic triac AC voltage regulator in front of the flashlight

[indigo plover]

You understand his question??

[spiral sandal]

i guess he want to power on/off something with potientally dangerous AC feedback with a phone light

[indigo plover]

I see. My guess was that he wanted a bigger transistor, but got sidetracked asking how transistor amplification works

[spiral sandal]

when i hear "big ac" i raise my optocoupler

a LDR in that will do for dirt cheap

search for "ac dimmer"

[indigo plover]

Bro if he's asking for basic information about "big AC", do you think it wise to give him partial information? 💀

[spiral sandal]

we'll see, but yeah of course put everything in a locked box and keep indoor ( but kinda obvious with the phone )

[indigo plover]

Is it obvious? Because it seems to me 1) extrapolation of meaning is done on that gibberish we are reading, 2) if he's asking questions about medium voltage applications, he really ought to not play with it

[stoic pewter]

does someone know if you can use assembly on a arduino nano?

[willow kernel]

(I recommended he ask here, so if not a great place to ask, blame the Hemlock)

[indigo plover]

Yes

https://en.cppreference.com/w/c/language/asm

[quaint nacelle]

an Arduino Nano is an ATmega328 chip, so you just need an assembler for that.

AVR-GCC is the toolchain I think people mostly use?

https://gcc.gnu.org/wiki/avr-gcc#Inline_Assembly

[modern wigeon]

I didn't know Python could be utilized for microcontrollers, I thought that was a domain for C++.

It actually can be even better than C++ but Python is smoother while C++ is faster which means you have to first figure out what you wanna code needs to be fast or smooth and precise in the case of microcontrollers

[elfin sphinx]

what does "smoother" even mean

[elfin sphinx]

you can even write rust for it , javascript for some high end microcontrollers , there are tons of languages that you can use with microcontrollers.

[nimble badger]

dynamically, it runs the code smoother, esp when it comes to robotic arms. Python is super efficient in that case

[nimble badger]

there is tons of languages to be used but it optimally depends on the application for which you wanna use the microcontroller for

has anyone worked with ROS ?

[elfin sphinx]

how is "dynamically " getting translated to "smoother" ? ? i dont understand

"python is super efficient" in terms of what ?? using resources ? speed ?

you said "python is smoother" , and then you said "smoother means dynamic" , so are you trying to say "python is smoother dynamically" ?? makes no sense to me

and if you say that "python code makes the movement of robot arms smoother" , then that has no meaning because you should be able to do everything in C++ as well.

the things taht cause movements to be not smoother is code. if you write bad code , teh movement will not smooth , regardless of if code is python or c++.

dynamically typed languages take up more resources than compiled ones. and resources is the one thing that we dont have much of when it comes to microcontrollers.

"it runs the code smoother" , dont even know what that means

[nimble badger]

you might have to google its definition then xd take it easy man! we're not in a word battle! we're here to learn so I hope you didn't take it personally!

[elfin sphinx]

i still dont see the word smooth defined anywhere : )

efficiency is a totally different term

and in fact C++ is more efficeint when it comes to using resources than python (efficient as in , it uses less resources in the end)

im not trying to battle or anything , im just trying to understand your point of view as i didnt understand what you were trying to say

you were saying things like "you need to figure out if you want your code to be fast or smooth and precise" and from what i can see , C++ can do all 3. Its fast, "smooth" (or efficient as you are trying to imply) and "precise"(dont even know what you implied by taht , but whatever) 🤷‍♂️

[elfin sphinx]

thats just a random definition you pulled out , dont know how this relates to our convo

[nimble badger]

of course C++ is as great as Python! i'm working with C++ now

[elfin sphinx]

again , just generic talk is not helping : )

[nimble badger]

👍

[cloud hinge]

I use python in conjunction with micro controllers to control them and it seem like a win win situation having the best of both worlds

[cloud hinge]

What micro controllers allow java to written on them? that sounds interesting

[elfin sphinx]

one that i know which uses javascript is ESP chip , not sure which exactly , but i have heard you can use js on esp chips

[cloud hinge]

Awesome, thanks for the info. Found this site for it https://www.espruino.com/ looks like it's lightweight java witch is super interesting but I dont know much about java yet

[verbal marsh]

i'm thinking of learning some electronics by working on a project and i've chosen the raspberry pico W for the microcontroller. it seems that some components use 5V for its logic level so it may not work for the pico which uses 3.3V. i'm wondering, is this a huge issue in buying the components for my project? it's a simple alarm clock and i'll need an LCD screen, RTC, buzzer and some buttons for instance, should I also look into getting components to convert 5V to 3.3V?

[elfin sphinx]

you need a logic level shifter yes.

usually a lot of modules if they support 5V logic level , there is a very high chance they support 3.3V as well. you should check the datasheet of the module to confirm.

but if you do somehow end up in a situation where u have to interface a module that only works on 5V logic level with pico , you can buy a logic level shifter module like this one , its very cheap and it can convert both 5V to 3.3V as well as 3.3V to 5V https://learn.sparkfun.com/tutorials/bi-directional-logic-level-converter-hookup-guide/all

i wouldnt worry too much about it during component selection. and i would buy a bunch of those logic level shifters just to have on hand , they are pretty cheap , you can get like 3-4 of them (4 channels each) for like 1 USD

[verbal marsh]

ohh, gotcha. thanks for the tutorial link

[fast wagon]

is it possible to store files on an arduino r4 minima

i'm not able to find anything only specific to this model

like just as an example, if i were to try storing a text file in the arduino

[indigo plover]

Technically, yes

You would have to roll your own file system or port an existing one

Unless someone is kind enough to maintain one for you

[fast wagon]

i see

so it's not as simple as just creating the file with fstream and then pushing that to the board

[indigo plover]

Nope

#embed will change that up a bit, but you'll have to use C... unless it is enabled as an extension for whichever C++ compiler you use

[tawny zephyr]

Hey everyone anyone got the d.py tag?

[fast wagon]

oh yeah my bad i should have specified, this is with using C

[indigo plover]

Then you may be in luck

[alpine dew]

Yo im planning on buying a Raspberry pi pico to turn into a rubby ducky usb and troll my friends any ideas on what I should make it do NO I WILL NOT MAKE IT DELETE THEIR SYSTEM32

[near drift]

I seem to have fried my esp32 and i'm not sure how

The pwr led will not illuminate anymore

I don't think i was doing anything to short it. Had my led matrix plugged into the gpio pins as before and was trying to flash some new code onto it

Had done this routine dozens of times before. Not sure what heppened

It doesn't look damaged or anything and no smoke

[drifting bluff]

i am new to python clearly i have much to learn what is a rubber ducky usb and like what do you mean turn into ahh migrainsnjnjs

[alpine dew]

Ok so a rubber ducky is a USB that can autorun pre-coded payloads and it emulates an HID to trick the pc they are pretty cool

@drifting bluff

[drifting bluff]

cant that be used mali-- nvm

[alpine dew]

Yeah it's very common but they can also be used for harmless pranks

[drifting bluff]

oh, like what

[alpine dew]

Making a rickroll play with no traces idk tbh I havent explored it enough yet

[drifting bluff]

wait how do you turn a microcontroller into a usb, a usb flash drive?

[alpine dew]

A microcontroller cant be a USB and a USB cant be a microcontroller they are very different things

[drifting bluff]

do you have a little youtube vid or site about this stuff because idk anything abt this clearly how do you get a usb to force run code with a quick plug in it seems somewhat possible but with only a rasp pi tho it then seems somewhat impossible

[alpine dew]

There's applications online but they are not the most reliable I am going to bed now anymore questions can be left here for another member to answer or directed to my DMs and I can answer them in the morning

[leaden bramble]

not exactly true

you can emulate a storage device with stuff like tinyusb

and the other way around because of stuff like https://hackmag.com/security/rubber-ducky/

[quaint nacelle]

and on the extreme end of that there's stuff like https://www.embedded.com/soft-peripherals/ where ALL of the I/O is software

(I use some music players that have this chip in them)

At 250MHz, the IP3023 can emulate most serial or parallel interfaces out there. In addition to 100Mbps Ethernet, 802.11g WiFi, Utopia, Bluetooth, and HomePlug are all within its grasp. Each is implemented as a software state machine that makes greater or lesser demands on the processor, depending on its complexity and speed. A PCI interface, for example, is a 200-instruction loop that takes up about one-tenth of the processor's horsepower.
``` bizarre

but I guess if you're a DSP programmer at heart and want to approach other problems the same way, well Ubicom has your jam

[drifting bluff]

oooo

[drifting bluff]

whats a dsp programmer im new here

[quaint nacelle]

DSPs are "Digital Signal Processors".. Ken Thompson of UNIX/UTF-8/Go fame believes they are the worst thing to program for in the world.

[drifting bluff]

where in the world do i learn this ducky language

[quaint nacelle]

It's basically like only having math as your coding tool I guess? I can't claim to "be" one (yet?)

Lemme find an example

[drifting bluff]

oh i knew that but not the acronym

[quaint nacelle]

Like, bonkers levels of depth/alien-ness https://ccrma.stanford.edu/~jos/pasp/

[drifting bluff]

ok but like how do i learn the ducky language

[quaint nacelle]

https://www.dsprelated.com/showcode/31.php

[drifting bluff]

yet????

[quaint nacelle]

I mean, arguably I should eventually learn the assembly language for one of these beasts and try teaching it to do something

I feel like what Ken Thomspon was talking about is the fact that DSP instructions can be super complex mathematical functions, and it's hard for regular compilers to generate good code for them

So you end up having to write assembly every time

[drifting bluff]

where do you even learn assembly and why does it get no love

[quaint nacelle]

I guess this is what I should have linked https://www.analog.com/en/lp/001/beginners-guide-to-dsp.html

[quaint nacelle]

This guy's books are fantastic, there's even an ARM one now: https://www.amazon.com/Art-ARM-Assembly-Randall-Hyde/dp/1718502826/

[drifting bluff]

but like where to learn ducky language

[quaint nacelle]

The cursed thing is that assembly is different for every hardware architecture

so ARM assembly looks not much like Intel/x86 assembly

But ARM is a fun one to learn currently, and the Randall Hyde books are lovely

My first language was 6502 assembly on the Commodore 64.

I mostly typed in game code I saw in magazines

and then I would try to change something without breaking it

I honestly don't remember much 6502 at this point, but it did teach me what was going on

[drifting bluff]

commodore 64 is hype

but like ducky language

[quaint nacelle]

So.. which one do you mean by "ducky" then?

Sometimes it's actually really hard to find docs without paying some manufacturer money, which is irritating.

[drifting bluff]

i think its called ducky script

[quaint nacelle]

Ohhhh, you mean for this USB thing from above?

https://docs.hak5.org/hak5-usb-rubber-ducky/ducky-script-basics/hello-world

My bad, this is nothing like assembly, more like BASIC or DOS batch language.

[drifting bluff]

ty

[quaint nacelle]

I thought "ducky" was brainrot for "low-level" or "machine"

[drifting bluff]

wahhhhhhh???

[elfin sphinx]

google "pi pico rubber ducky" there should be countless videos on it

if you need a specific one , google a youtuber named "networkchuck" he has a video on it

[compact geyser]

on a raspberry pi, it is better to use bluetoothctl as a subprocess or to use pybluez library . Python programming

?

[fast wagon]

why does he believe that lol

also i feel like there's not much attention towards lidar and radar sensors within the dsp community

this is the part of dsp i'm mainly into

lidar, radar, ultrasound, and any other sensors beneficial to drones and autonomous vehicles

[indigo plover]

Imo, phased arrays aren't pleasant to design. Beamforming is still a hard engineering challenge. In the absence of accessible and useful CAD tools for beamforming, the community will keep this level of disinterest

[fast wagon]

but the same principles are still needed right

[indigo plover]

Which ones and where?

[fast wagon]

like the general principles of dsp

whatever is taught in a normal dsp textbook/class

[glacial stone]

sure, it's phase, time delay, and sensitivity to timing and data rate

and digital scales better in some use cases

[glacial stone]

i doubt that programming DSP is any harder than designing analog SP circuits..

[indigo plover]

Okay I see what you mean. The answer is as such: the problem is not the signal processing or programming a DSP; the problem is engineering antennae and testing the phased array. The textbook will show you how to ride a bicycle; phased array are flying plane. On top of that, you hit the problem that beamforming and whatever modulation you use on top should follow FCC regulations. The moment Maxwell's equations become accessible to the layman is the moment you will see tutorials on beamforming

[fast wagon]

i see

so would it be best to not focus on classic dsp then?

or should i still learn dsp as usual but along with that

would ultrasound be classic dsp without the extra problems you mentioned?

[indigo plover]

Yes. Although you would have to also do some wave physics. Air isn't a linear medium... at all. That's how you can produce a Doppler shift from mechanical waves simply colliding in mid-air. But yes, doing an ultrasonic phased array is a good start in this field. I recommend it

[fast wagon]

and usually how would these be simulated

like if i was doing it on my own

probably gonna be a while before i can work on making my own sensors

[quaint nacelle]

This is hilariously long but I also haven't really seen a more-comprehensive start-to-finish CPU architecture walkthrough https://www.youtube.com/watch?v=jC_z1vL1OCI if anyone is interested.

(I'm not normally a giant Casey fan but he's not ranting about anything in this)

[indigo plover]

I'd say writing your own Python script for wave simulation is the way to go. There are lots of modules for that. Fortran is also really good for that, but not as modern. Start with a 2D array to begin with. Assume air is a linear medium and build your simulator in consequence

[indigo plover]

For what purpose would you need to make your own sensors?

[fast wagon]

if i wanted to work on my own drone projects completely from scratch

[indigo plover]

And which sensor are we talking about?

[fast wagon]

ultrasonic

though in the future i also want to be able to implement lidar and radar sensors too

my focus for drones is lidar, radar, ultrasound, and computer vision

[indigo plover]

So you want to make ultrasonic transducers?

[fast wagon]

i have no clue what a transducer is

i think i should just focus on learning right now

i know far too little to be thinking about this stuff

[fast wagon]

seeing what it means, yeah that's probably what i'm thinking of

[indigo plover]

Well, have fun 😇

[halcyon dagger]

How fast can the Raspberry Pi 4b read the GPIO pins as input using the RPi.GPIO library? I read that the pi3 cant do much more than 20kHz but I don't know about the pi4b.
I need to read 5 pins at 88kHz, should I use RPi.GPIO or a C library?

[indigo plover]

https://datasheets.raspberrypi.com/bcm2711/bcm2711-peripherals.pdf
5.4.1. Operating Frequency
The maximum operating frequency of the General Purpose clocks is ~125MHz at 1.2V but this will be reduced if the GPIO
pins are heavily loaded or have a capacitive load.

This is for the Pi 4b

[halcyon dagger]

Thanks!

[limber field]

[indigo plover]

What kind of ideas do you have in mind?

[limber field]

Well tried to get , RPITX2 , to work all I can do is 250 Khz to 100 Mhz , if outside that range a lockup or glitchyness occurs @indigo plover

https://github.com/KubaPro010/rpitx2

[indigo plover]

That's pretty cool! What specific hardware do you use?

[limber field]

RPI3B+ , since its been gathering dust . I want to try and make a Tkinter control panel for it then use it as a clock / RF source for experiments @indigo plover

RPTIX2 , claims to do - 5 Khz to 1.5Ghz

[indigo plover]

Yeah, I looked into it... I personally wouldn't use it. This thing is dishing out some solid EM pollution thanks to it's lack of a proper transmitter. The creator doesn't formally recommend its use. If you want to use this, an empty field is your best bet next to making a Faraday cage

Rpitx2 is a software made for educational on RF system. It has not been tested for compliance with regulations governing transmission of radio signals. You are responsible for using your Raspberry Pi legally.
It's a fun toy, but you'll get the FCC with police at your doorstep in no time

Does lvgl work in mpython and python. Nice project!

[spiral sandal]

lvgl works on micropython, cpython, both native and webassembly

but since it is cffi beware of cpython garbage collection it is way more aggressive than micropython (mark and sweep)

[fast geyser]

Oo

Aurdino works?

@safe summit yo

[safe summit]

It's a Waveshare Pico LCD 1.8 + ESP32-C6-Pico

[safe summit]

just a note the ESP32-C6-Pico isn't super compatiable with this lcd hat and I wouldn't recommend using it for reasons mentioned here https://github.com/orgs/micropython/discussions/17413 they didn't quite clone the GPIO pins right getting a different board later ~

[safe summit]

so turns out it might be a MicroPython bug fun 🙃

[drifting bluff]

i got the microcircut python thingy on a raspberry pi pico what else do i need to do inorder to turn it into a payload injector? like the rubeer ducky

[drifting bluff]

like which github thingy has the thing that disguises the pico as a hid and the other ducky script converter

[near drift]

The stuff is finally here

[elfin sphinx]

nicee

what are you making ? weather station of sorts ?

or is that distance sensor ?

[near drift]

yeah it's a temp humidity sensor. I'm making an led matrix display to hang up on my wall

I fried my last esp32 during development of the code. Not sure what I did wrong. Ordered 2 more and had to spend couple bucks extra for free shipping so i bought the sensor

[elfin sphinx]

ooo noice

[elfin sphinx]

xdd

they always get me with the "orders over X are eligible for free shipping " too

[near drift]

it actually made sense though because the value of the sensor was more than the shipping would have cost. So it was basically free

[safe summit]

recenty made this waiting for more modules to fill it out ~

[balmy lichen]

how do u connect multiple 5v modules on a pico if it only has one vbus port capable of delivering 5v?

can u buy like power boards that connect to the vbus and provide several more ports?

[swift horizon]

Hlo guys

[elfin sphinx]

Usually you just connect them directly to the 5v source. If I am not wrong , on the pico , the vubs pin is directly connected to the vcc pin of the usb power supply, so as long as your usb power supply is capable enough , you can attach multiple 5v modules to the same pin .

[balmy lichen]

how do u read schematics?

it looks nothing like it

but apparently it is

heeeeeeelppppp

[drifting mesa]

on the schematic:

• GP15 connects to resister R1 side 1
• resister R1 side 2 connects to LED1 side 1 (+, the longer lead)
• LED1 side 2 (-, the shorter lead) connects to ground

on the "image":

• GP15 conencts to one of the resister leads
• the other resister lead connects to the long lead (+) of the LED
• the shorter lead (-) of the LED connects to a wire
• the wire jumps around, connecting to a GND pin on the pico
  remember:
• on each half of the center of a breadboard, columns are connected together
• resistors do not have polarity - they cannot be "backwards"

[balmy lichen]

whats side 2?

the right side?

theres nothing there tho

[drifting mesa]

i'm referencing the schematic's numbers, but on a resistor, the side are equivalent

put an LED or several other types of components in backwards, and it might be damaged, but a resistor doesn't care

[balmy lichen]

is the schematic different to the second image?

[drifting mesa]

technically, yes, as the schematic doesn't use the pico's ground pin, but that's a minor detail. the circuitry is equivalent

[balmy lichen]

how do i even learn to read it?

i dont see any correlation between those two images

whats this type of stuff called?

on google searching up for electrical schematic guides brings up things of completely different format

bruh theres literally no resources for reading microcontroller schematics

[elfin sphinx]

usually you will be dealing with the schematics shown on the left hand side , you wont see "images of circuit" like on the right hand side

as to "how do i read it ? "
well the first thing is to know what all the symbols for electronic components are , and knowing basic about them

like knowing what the symbol of resistor is , knowing the fact that resistors have no polarity , meaning they can be connected in any orientation and that wont affect their working etc etc

after that , the schematics are pretty straightforward as thuri explained.

if you have specific schematics and you need help with them , feel free to ask here

i dont really know how else to "teach" someone how to do this without working through few schematics

[balmy lichen]

whats it mean when its green?

like here

whys it green

is it to do with the positive side of the breadboard or something

and if ur reading in schematics how do you know where to plug what?

[elfin sphinx]

in this case i dont see any particular meaning other than green showing that the pin is being used. and red would probably mean the pin is not used / connected anywhere

but its not a "rule" , its probably the PCB design software's way of telling you that you ahve used this pin

[elfin sphinx]

no

[elfin sphinx]

because the schematic tells me where to plug what

in the above one, the schematic tells me that , i am supposed to connect one side of the resistor to GP15 pin and the other side of that resistor to the anode(+ terminal) of an LED. the other terminal of the LED is show to be connected to ground.

are you aware of what different symbols mean in a schematic ? like the symbol of a resistor , capacitor etc ?

thats a very important part of reading a schematic

[balmy lichen]

yeah i do

[elfin sphinx]

then you should be good to go

try to read more schematics and ask wheere you are stuck

thats pretty much how you learn (or at least thats how i learnt it , i havent seen a cours for it or smth)

[mortal bronze]

Can someone recommend me an application which can simulate microcontrollers and stuff

[elfin sphinx]

https://wokwi.com/

[mortal bronze]

Thank you, Saul Goodman.

[near gulch]

im working on a home automation project
and for that im searching for a very low power and cheap microcontroller to turn relays on/off when it receives a signal (via wifi or blutooth)

I was thinking to go with an esp32, especially because of the esp-now protocol
but im not sure which board to use

[near gulch]

so basically i want the microcontroller to be energy efficient and atleast 10 digital io pins
and a built in wirteless communication method (preferebly esp-now)

[elfin sphinx]

from wht i know about the ESP32 wroom module ( the default ESP32 board like the one u see in the embed of above link)

it has some sort of light sleep mode where it keeps the wifi connection on , and it consumes about 5 mA or so doing that

so thats probably the lowest power consumption that you will be able to get out of it with wifi

not sure if thats energy efficient enough for you though

wifi burns a signficant amount of power so its kinda hard to be energy efficient with it

unless you do like a "interval based checkup" where you periodically wake up esp32 from deep sleep and then check if there is some data queued up for it or smth like that

dont know about pi pico W

also pretty sure STM32 has some sort of low power , wireless enabled chip too

if you go for pure power comparison , then ESP8266 will be a good bet as it consumes less overall power ( about 100mA) as compared to ESP32(200+ mA) when using wifi

but again , its a little weaker and it has a lot of its pins bootstrapped ( their pin states cannot be guranteed when ESP boots up , so random relays may get activiated during ESP bootup)

[near gulch]

oh i see

rn im using an esp32-s3-wroom-1
and it seemed overkill to use that because there are cheaper boards,
and because all im doing is just waiting for a signal and just turning 5-10 relays on/off

[balmy lichen]

whats the arrow besides the diode mean?

and also here there is a symbol for a junction that leads to a resistor into 3v3 and on the other side a switch that leads to ground. how does that work?

why does this just cut off?

[elfin sphinx]

that is the symbol of LEDs

[elfin sphinx]

you take a switch with 2 pins , to its one pin , you connect a 10k resistor and you connect the other side of that resistor 3.3V.
to the same pin of the swithc, you connect another 10k resister which connects to the GP13 pin

and finally , on the second side of switch , you connect it to ground

[elfin sphinx]

thats they symbol for the switch.

the schmatic uses switch with 4 terminals but makes use of only 2 so thats why the other 2 terminals are just green

[balmy lichen]

so if the junction connects to the switch and the resistor, what is the junction itself?

like i get how everything else is wired except for the junction

[elfin sphinx]

Junction is just a point where lot of connections are made. It's not a physical thing like a switch. Like if you solder together 3 wires , the point where they are soldered is a junction

[balmy lichen]

so does that basically mean the button pin column has to be on the column of the resistor

does the junction just mean they are both in a spot that receives the same electrical power

like on the same terminal strip

[elfin sphinx]

Yes , pretty much.

[balmy lichen]

should i put the button over the center divider?

[elfin sphinx]

All the 3 parts that are connected to a junction go in the same column of the breadboard so they are connected together

[elfin sphinx]

Think about it

How will the electric connections be formed

Also depends on what kind of button u r using

[balmy lichen]

it has four feet

two on each side

push button

so would putting the button on top of the center divider be required cuz there has to be opposite wiring

[elfin sphinx]

well thats the point yes

if you are using a tactile switch like the one show in picture , the pins i circled will be the ones you would wire , and yes , you would need them to be on the different sides of divider . if you put both the pins in the same column in the same side of divider , they will just be shorted together which we DONT want

[paper pike]

Is there a sensor for reading DNA?

[indigo plover]

Not really

[paper pike]

What's one possible way?

[elfin sphinx]

going to a lab and submitting blood sample so they can run the DNA test on their multimillion dollar machine

why do you want a DNA sesnor ?

[indigo plover]

Yeah. Basically, you sensor bills you for a few thousand dollars every time you make a measurement and takes 4 weeks to produce the sequenced DNA

[paper pike]

Make a cheap affordable way to test if somebody has a specific genetic disorder and they can't go to the hospital because of that disorder

[elfin sphinx]

ok , so , there isnt any DNA sensor that you can just buy for few bucks and hook up to arduino , such thing doesnt exist
if it was possible to make such a complicated machine like that, it would have already been done by someone

You said you want to check if someone has a Specific genetic disorder

so what you should do is , go to a lab , see how they do the test , check what exactly they do ( im no chemsit but what they probably od is draw your blood and run various chemical tests on it and check their results ) . and find the test that they do for your genetic disorder

then , you should find some way to do all this with your device

@paper pike here is the handheldest DNA sequencing device
https://nanoporetech.com/products/sequence/minion
Yes. It costs 5'000$

[willow star]

I'm actually very surprised at how cheap this is, I would assume a machine like this would cost hundreds of thousands of dollars minimum

[indigo plover]

Yes. The training is 7'000$. The base device is 3'000$. The flow cells are 200$ each

[elfin sphinx]

Although im sure it has its limitations in some way

[worn sparrow]

that's what i thought

[indigo plover]

That said, all that microfluidics research is paying off

[rocky sparrow]

so I have a (rather old) previous laptop with a dead battery
would it be overkill to take out the mother board and use it as a glorified Raspberry pi?

[elfin sphinx]

not really , its a good option
also why would you take out the motherboard ? just use it as is , it should still work perfectly fine.

[rocky sparrow]

fair
removing the keyboard and screen might be a bit of a pain though

since I'm planning on using it as part of a cosplay
though I am no where near building a human size Gundam

[elfin sphinx]

why do you want a full blown computer as a part of your cosplay ?

[indigo plover]

How do you plan on using this motherboard to do IO?

[rocky sparrow]

lights and a few other features

[rocky sparrow]

plug in desktop peripherals, load script from USB then unplug everything

[elfin sphinx]

what "few other features" ?

because you usually woudl use a PC /raspberry pi when you need tons of heavy processing power for stuff like running a webserver or gameserver or stuff like that

if you need to light few LEDs, you should use arduino

[rocky sparrow]

no idea if this will actually happen but since I'm thinking of a WFM mech, (Probably Aerial) having the shield be a few drones that hover around me

[elfin sphinx]

.....no idea what you just said , what is a WFM mech ? and what is a shield be a few drones taht hover around you ?

[rocky sparrow]

a Gundam
one of the mechs has a shield that's also a few drones sometimes

[elfin sphinx]

a singular shield is a few drones ?

also what is a gundam

can u explain it like a person has no idea what u are talking about ?

and more importantly , what are you going to use the raspberry pi / pc for ?

[safe summit]

FYI none of this chat is on topic pis are not microcontrollers

[elfin sphinx]

pis can definately be discussed here

[safe summit]

Oh my bad sorry

[rocky sparrow]

a giant robot
I just meant instead of buying more stuff using an old laptop
its 7 small drones that come together to form a shield
not quite sure if I want to go that far, might just buy an arduino to make the lights do what I want them to and leave the shield as one piece

[indigo plover]

By drone do you mean flying ones?

[rocky sparrow]

yes

[indigo plover]

Ah!

Gfl

[rocky sparrow]

its that big of a pain?

[indigo plover]

Massive

Cool idea, though

[rocky sparrow]

even if I just had it circle me in place?

[indigo plover]

Same difficulty

[rocky sparrow]

fair enough

[indigo plover]

This is a big engineering challenge. It's not impossible, but it's the kind of thing you need a team to work on or just be dedicated alone for years

The tech to make this easy does not exist yet

[safe summit]

I'm here for laptop voltron

[ebon pier]

i wanna make my own ipad and computer and servers

like how would i make a server like a pc

[near drift]

i'm not really sure what you mean

[elfin sphinx]

a server is just a PC , so if you have a PC , you already have a server

[sturdy tulip]

and "making a computer" is a very broad category with varying levels of DIY depending on what you actually want to do.

[limber field]

start simple Z80 or 6502 , get the concepts , look at 68000 CPU , look at pipelining structures

[spiral sandal]

or 8086 which is heavily documented, and run https://github.com/ghaerr/elks on it

[ebon pier]

Do you think if I mod a laptop the correct way I could use that maybe?

[elfin sphinx]

what do you mean by "mod the correct way" ?

[limber field]

When modding - boxing gloves should not be worn @elfin sphinx

[mighty stratus]

You can use clouding services like AWS.

[ebon pier]

Like get pc parts and other shit and solider and do the work and basically turn it into a pc/server or nah

[spiral sandal]

to assemble pc parts you only need a philips screwdriver, though sometimes it can lay on a isolated plane while testing

[elfin sphinx]

it already is a server , just load it with a server OS and you can treat your laptop/PC like a server

[oak quail]

Hey.I would like to create my own server.I found out there are this things called NAS servers but they are soooo expensive. Could I perhaps be able to build myy custom "NAS server" using a raspberry pi? And if I do, I assume the connection to it would be made using the local network.Is there a way to connect to my server from another place?

I hope I addressed this matter in the good channel

[elfin sphinx]

you can do that in multiple ways

first and most obvious would be to expose a port from your wifi router. This is pretty risky if you dont know what you are doing. you are essentially opening up a door from your house to the whole world.

next one would be setting up a VPN server alongside the NAS software on your raspberry pi . and use that to connect to your pi remotely . this will still require you opening up a port (afaik) but , it is a lot more secure as you can control who connects to the VPN

another one would be to route your NAS over something like cloudflare tunnels. This is alos fairly secure option to do it and doesnt require you to open any ports or anything like that

[elfin sphinx]

well , i would say your question is pretty much totally irrelevent to this channel as this has pretty much nothing to do with python . but ill answer anyway 🤷

[oak quail]

well isn t raspberry pi python related?

Sorry I am not very experienced in this matter

[elfin sphinx]

sure

if we go by that logic , even my pc has python installed. doesnt mean i can ask question abaout how to setup windows on it in a python channel ?

but as i said before , i have answered it anyways

[elfin sphinx]

nah u r fine

[oak quail]

Ok thanks

[marsh iron]

[hexed bronze]

I have arduino but i just know coding python. Can i code my arduino with python?

[indigo plover]

https://realpython.com/arduino-python/

[elfin sphinx]

(with this , you are not really writing code on the arduino . you are telling your PC how to control arduino , which are a little bit different . With pyfirmata ,you would need to have your arduino always attached to your computer when you want to run the code.)

if you want to write code for arduino , you will need C++

[indigo plover]

We agree

[ebon pier]

Kk

[trim condor]

so whenever i wanted to turn it on using python , it will requires the PC being attached to it ?

[elfin sphinx]

yes, to control the arduino wtih pyfirmata , you would need to have it connected to your PC always

but , if you write code for the actual arduino in C++ , you dont have to do that

[trim condor]

i see , so it will make your life easier using C++ , but incase if i only know python its better to take Raspberry PI ?

[elfin sphinx]

it depends on your project
if your project is going to be plugged into the PC when you want to run it anyways , its fine to use pyfirmata
but yea , C++ in general will allow you the most flexibility

and about the other question , rasppberry pi and arduino are not exactly replacement for each other , they both are different things serving different purposes.

raspberry pi is a small computer , its insanely more powerful than an arduino. like ,if an arduino is a bicycle , the rpi is a fighter jet.

Technically , yes , you could use rpi where you used arduino , but its very overkill

[warm birch]

I have an esp32, Im okay at python, know a lil C but would be starting fresh with C++ should I be using micropython, or learn C++?

[warm birch]

is this also true for an esp32 with micropython?

[elfin sphinx]

if you want to learn more microcontrollers and learn more about hardware in general , C/C++ is always good to know well

[elfin sphinx]

no

the micropython code actually lives on ESP32 and executes on it , you dont need to have it attached to computer

[gloomy granite]

cool

[hollow quail]

Not quite sure where to ask this but does anyone know how to emulate a VR controller input? And if so, what data would be required?

I currently have two devices with accelerometers and buttons that can be connected to a computer through python and data can be read from them

So ideally, there should be some way to translate this data into something that can be recognized by software as two VR controllers

[spiral sandal]

not microcontroller stuff indeed, better use linux and create your own userland input device with something like https://github.com/pyinput/python-uinput . That way you could probably fake any physical controller api like wiimote or https://github.com/rdady/gear-vr-controller-linux/blob/master/gearVRC.py

[hollow quail]

Hmm, I am looking for something that works on windows, unfortunately. I appreciate the responce, though ^^

[spiral sandal]

if you want cross platform go for WebXR controller emulation

or expect to loose your time

these vr platforms all want to create their private ecosystems

[hollow quail]

Ty! I'll look into that!

[limber field]

[cyan bear]

@brittle grove

[finite inlet]

what are good microcontrollers

[spiral sandal]

you need to specify level of "cheap" and "support" for amount of "good"

there's a whole zoo out there

also do you want to run any python ON the board, or just drive it from cpython native or web

personnaly i've found that esp8266 mini-D1 can fit in most situations

[finite inlet]

i want to run python

[spiral sandal]

well esp8266 is the smallest, cheapest that can also be remotely driven by cpython+telemetrix

but it only give just around 32kB sram for micropython bytecode that's not much, nb not cpython

[frozen patrol]

I would go a pico, it’s what I use, I’m not the best with microcontrollers but it’s very easy and can run python(micropython)

@spiral sandal

[spiral sandal]

less cheaper, longer board but way more sram, beware the cheapest clones have no wifi

support is good especially with micropython

[cunning lance]

thanks a lot for approaching

its too late

[strange sail]

Hello everybody. I'm new here, but I faced a significant challenge with my Pico 2 W. I have a work environment that has three electronic gates. No one would provide me with a remote for these gates that could be mounted to a vehicle, and they don't have the right RF receiver. These gates can be opened with an API, so I figured I could build something with a microcontroller with Wi-Fi access that could talk to the API and open the gates. I could hook up an LED and some buttons and the battery pack.

So I did and I got it to work, but it was burning through batteries. I needed to get the device into a light sleep or deep sleep mode. No problem, or so I thought.

I couldn't get light sleep or deep sleep to work the way I wanted, at least not with micropython. All I could get was light sleep to work with a timer, but that was no good for my application. I needed the device to wake on a button press, a GPIO signal.

It was impossible with the micropython 1.25.0 firmware or any of the preview builds I was provided on the micropython website. I looked on the internet and found a bunch of people had the same issue with no resolution. The conclusion was that some of the capability of the Pico 2 W was not exposed to the micropython firmware.

The Pico 2 would either go to sleep and never wake up, or it would go to sleep and wake up immediately.

The solution? I made my own version of micropython firmware for Pico 2 W preview build that I called Pico2_W_Wake. I'm not ashamed to admit that I heavily relied on AI (I'm not good with C).

It still took me a week of on and off tinkering to get it to work, but it does. Both light sleep and deep sleep work, and the power savings are amazing! Deep sleep is especially impressive. It's been weeks, and my WiFi remote device is still running on AA batteries, nowhere near dead.

The project took enough work that I'd like to share my knowledge gains, but I don't know where or how. So I came here 🤷‍♂️

[elfin sphinx]

well the most important part of the prjoect would have been explaining the code , why everything is used the way it is used and documenting it in general etc
but given that most of the code is AI , i am not sure what can be more useful compared to the C++ SDK docs of pico

i think the best option for you is put all your code in a github repo and make a reddit post in subreddit for pico showing the project

[strange sail]

I can explain how a lot of it works (but maybe not all of it), and I can certainly explain what changed and give some good examples of micropython using deepsleep and lightsleep, monitoring the pins I specify for pin wakeup.

Which Reddit do I go to?

[limber field]

Hi

I need to understand arduino connection if anyone can help

Trying to sort led connection

[elfin sphinx]

What do you need help with exactly from us ?

[placid jolt]

Like i want to understand breadboards connection

[elfin sphinx]

Ok, but what are you expecting from us ? Do you just want a paragraph explaining what breadboard connections work ? Because that's a terrible way of learning how to do breadboard , you should watch YouTube tutorials imo

And after that if you have any specific doubts , we can help

[placid jolt]

Oh okay i will brainstorms some connection

[elfin sphinx]

If you don't know how breadboard works , wouldn't it be a wise step to learn how it works first ?

Also do you have a breadboard at home to try the connections onto ?

[placid jolt]

One thing i cant understand is how current is flowing through it

Like the direction i cant visualise

[placid jolt]

I haven’t but i have physically seen one

[elfin sphinx]

From positive end of supply to negative

[elfin sphinx]

Then how do you intend to practice the skill ? One way might be to try online website like tinkercad ig , if they have a breadboard

[elfin sphinx]

Have you watched a tutorial

[placid jolt]

Im using tinkercad

[placid jolt]

Im watching rn

[placid jolt]

Hey i just watched some tutorials and was successful in building a blinking led but when i try putting more than 1 led in same set up i was unsuccessful

I will send the screenshot

Idk i just couldnt figure out the problem even after visualising current flow

Maybe im just bad

[frank sentinel]

what's your code

@placid jolt

[placid jolt]

Theres no code

[reef moat]

you don’t have a negative

you need a negative wire

[placid jolt]

For 2nd led?

[frank sentinel]

if you have no code how did you get it blinking?

[reef moat]

yeah i’m assuming so

[frank sentinel]

how tf did the arduino magically know what you are trying to do to the LEDs?

[placid jolt]

Its glowing not blinking also this is ide code is wrote automatically in background

[reef moat]

there’s like chips

[frank sentinel]

oh sorry

[reef moat]

tbf i managed to make a blinking led without code

[weary heart]

by default the GPIO pins are zero (voltage low), afaik
if you just want them to glow you need to connect the LED between 5V and GND

[reef moat]

i used a motor to turn on and turn off a switch

[placid jolt]

Ok whatever but the point is 1st led is blinking but not the 2nd one

[weary heart]

are you using some premade code? because at some point there is going to be code involved here to get an LED to blink.

[placid jolt]

Look let me send u an screenshot

[frank sentinel]

this?

[weary heart]

my guess of the situation is that the code (which you haven't written nor seen) is only making one of the pins cycle in a blink pattern, therefore the LED connected to that pin is blinking. but there is no code to make the other pin do the same, hence no blink.

[frank sentinel]

apparently tinkercad gives you a default codeblock thing

[placid jolt]

U can see that first led is glowing but not the 2nd one

[weary heart]

yeah, so you're only making the LED_BUILTIN pin go high and low. that's pin 13.

there's no logic to make the same thing happen for pin 12.

this is why we asked you to show the code btw. it drives the logic, so it matters.

[placid jolt]

So what should i do then 2nd led also glow or blink?

[frank sentinel]

i mean... it's not python... but i suppose we could help

[weary heart]

look at the blocks available on your left-hand-side. does anything look useful, now that you know you need to make pin 12 go high and low?

[frank sentinel]

i thought you were going to teach C++ lol

[placid jolt]

First i want u to clarify if the connection is perfect or not

[frank sentinel]

the connection is correct

you just need logic to set pin 12

[weary heart]

the connection is fine. as I've said, it's just that you're not making pin 12 do anything.

[placid jolt]

Ok i understand

[reef moat]

scratch

[placid jolt]

Not quite getting it i would ask my university professor

[weary heart]

what are you not getting exactly

[elfin sphinx]

hi sorry i was AFK

looks like quite a bit has happened and im not sure where you are at right now

if you still need help , can you repost your screenshots , code , circuit and ask what you need help with ?

[weary heart]

did you try what I said? #microcontrollers message

[placid jolt]

Yea i looked all commands from left hand side

[weary heart]

nothing seemed useful? what about uh ||set pin X to HIGH||

[elfin sphinx]

so this LED should work as you want , the other LED wont work like the first one , is that correct ?

[placid jolt]

Yes the 2nd led isnt working

I doubt if there is error in connection from my side

[elfin sphinx]

lets understand why the first LED is working
and then we will come to the part why second wont work

both of your LEDs are connected to arduino's pin. This pin can either be HIGH or LOW. You have the freedom to give whatever command you want to pin.

in your code , you have digitalWrite(LED_BUILTIN, HIGH); line , what this line does is , tells your arduino to turn on the pin number 13 (which is the same as LED_BUILTIN) , and that is why your LED "works"

now , about the second LED , you have it connected to pin number 12 , but nowhere in your code you tell your arduino what to do with taht pin , so that pin stays off

if you want your second pin to work , you need to tell your arduino to make it on using the digitalWrite() functioon like you do for the other pin

you also will need to setup the LED using pinMode function in setup function

@placid jolt

[placid jolt]

Ahhh right

[elfin sphinx]

basically , you have to program arduino so that it knows what to do wiht these connected LEDs

[placid jolt]

I though the tinkercad would code in background for me

[elfin sphinx]

tinkercad has no idea what you intend to do with that pin

you can use a pin for a lot of stuff other than just blinking LEDs and tinkercad wont know what you want to do with it

[placid jolt]

Hmm

[elfin sphinx]

for example , you can have a pin output PWM signal to a LED , the circuit can look exactly same , but code is different

now how would tinkercad know if you want to blink it or PWM it ?

[placid jolt]

Which course are u pursuing ?

[placid jolt]

Ohh right

[elfin sphinx]

i completed my BTech in Electronics and Telecommunication engineering

[placid jolt]

Ohh im also doing Btech

Im just basically exploring stuff

[elfin sphinx]

good idea

[weary heart]

you can see what the code is, you don't need to assume stuff like that

They're called flex sensors. They basically measure the angle of rotation of a finger in a value of 0-1023

[restive laurel]

They measure resistance

[tidal haven]

@restive laurel

[restive laurel]

It's a device which measures your brain waves and uses it to do stuff. Like you can think of moving your arm without actually moving it, and it would move a robotic arm or something

[restive laurel]

?

[brisk zodiac]

which simulator i mean

@restive laurel

[brisk zodiac]

yea i saw a vid on that but i dont have it

It's a game I made on unity

[brisk zodiac]

oh cool project

[brisk zodiac]

ok

[tidal haven]

You could have a look at https://en.wikipedia.org/wiki/OpenBCI unless i'm mistaken they don't appear to have used common PCB design software though. They appear to use ADS1299 i think since its a 24 bit ADC, the pcb would presumably need to be pretty well designed to minimise noise

[brisk zodiac]

ts looks good

    if abs(xValue - beforexAxis) > 1000:
        servo_value = (min_duty + (xValue / 65535) * (max_duty - min_duty))

why doens't it revert to 90 degrees when idle? moving the joystick sweeps the servo correctly, but when i let go it stays stuck at 45 degrees and never anything i put in the else statement

[restive laurel]

[balmy dirge]

hey low level coders, I wanna brag about something.
I will build a whole operating system one day. hopefully a 64 bit one. from bare metal, even deeper than that. I will use actual electronic components

ICs, MOSFETs and BJTs, and of course all the other required components and material

it will take me a lot of time, but I will still do it some day

I can't promise it though

I will just try my best to achieve that

no matter how long that would take me. it could be even a decade

it's gonna be an interesting and painful journey!

something that I will most likely regret

ping me if you want to say something about it, all feedback will be appreciated

[lyric harbor]

Hey, I'd appreciate feedback on my schematic, its a devboard based on the RP2040, I've never done this before so chatGPT came in clutch, but that's why I'm also asking for reassurance.

i cant send the pdf so let me get a photo real fast.

[hallow igloo]

nuicew

[fiery lion]

Cool work man idk much about microcontrollers but this is some cool stuff

[primal vortex]

unable to provide feedback as I am not well educated on schematics but what did you use to make this?

[errant wigeon]

https://www.kicad.org/
KiCad is a open source tool for designing PCBs, and includes a schematic layout engine. It's pretty great, though there are lots of other tools out there too

[errant wigeon]

Adafruit has a discord and in it there's a "help with hw design" channel. They probably will be well suited to help out with schematic designs
They also have a few dev boards with the rp2040, and show their hardware design: https://learn.adafruit.com/adafruit-feather-rp2040-pico/downloads

[lyric harbor]

Ah thanks guys, appreciate it

[lyric harbor]

Yes, I used kicad, it was actually really simple to pick up if your ever interested

[urban junco]

Didn't know, kicad is this good

[hardy idol]

need help

[tidal haven]

[eternal sorrel]

Why not make a discord server to drop updates in and for prople with similar interests could talk

[balmy dirge]

I already own one discord server though. It's been very inactive and silent for years and lost hundreds of people.

[balmy dirge]

It's an interesting idea after all. But I don't think I could manage something like that. I am usually pretty busy.

[quaint nacelle]

"Zulip" is an interesting offering, it's like a hybrid of Slack and Discord and a forum, sorta

I made one for my "covert open source" friends, cool so far.

[eternal sorrel]

Oh well..

[balmy dirge]

Yeah. Anyway, are you interested?

[eternal sorrel]

Definitely

Hmu

[quaint nacelle]

Anybody in here ever programmed an "FPAA", an ANALOG programmable device? e.g. https://www.renesas.com/en/products/slg47004 ?

[balmy dirge]

Oh really? I'm surprised actually.

[eternal sorrel]

Haha fair enough actually, i just love knowledge

It tingles my brain when i learn something new

🤤

[balmy dirge]

I agree

[balmy dirge]

if you wanna know, I recently got some of the parts I will need!
it is already making progress!!

I really hope it will work once it's finished.
and this project is incredibly insane. what I am planning for it is. I will first make 64 bit registers and 64 bit ALU. very complex, yet still I will try to figure it out somehow. those will be main components of the cpu. after that I will either buy some kind of RAM chipset or even connect consumer RAM (at least ddr3) to it.
and once I get those main components and connect all that to work. I will make more hardware such as PS/2 or maybe even USB interface. I prefer PS/2 because it has lower latency and it's simpler to implement. and a VGA interface. I maybe know some place where there is a whole storage of old VGA monitors and cables that is planned to be thrown away, so I will maybe take one monitor. and once I make the VGA interface I will maybe make graphics interface. that is just the beginning. but before implementing any visible graphics I will try writing some kind of firmware and flash it to memory. and finally after all that goes actual software development. a custom compiled programming language (probably my own version of C, probably a hybrid of C. C++ and BASIC. I will not remake those languages, I will just combine the things from those languages that I like. for example in BASIC I like how it has peek and poke and I thought it could be pretty cool to add in my own language for my own computer. alright so after I make the language I will start coding even further. I will make a bootloader, a file system, a kernel, and beyond all that to the point where I make desktop environment and applications, and boom, a whole PERSONAL COMPUTER from scratch is done... kind of.
it is very extreme and sounds very impossible. but I am enough crazy for that kind of project. and I will truly try my best to get all the resources.

I still can't promise any of that. it is way too extreme for me and I highly doubt it is possible for me. and even if it is possible, it would take me a very long time. I won't promise anything

[eternal sorrel]

Damn going full terry davis mode!

Yo make a server for this specific purpose

And invite me

And I'll help with what i can

And learn new stuff from you

[brave prairie]

I'm new to micropython. Many years ago I've played with microcontrollers in C but I don't recall much. I'm now looking around micropython doc and I've read a little about interrupts. was just curious to know what are the most common way to organize code.

what kind of techniques do you use to achieve "multitasking" do you use asyncio? do you write some kind of state machine?
Sorry for the vague question, I'm just trying to build a very wide understanding 😅

[balmy dirge]

Maybe XD

[balmy dirge]

Like a whole community?

[balmy dirge]

I forgot to mention. If I actually build that thing. I'll also try making networking possible (wired). Maybe connect it to ethernet. There will be no speakers though. I don't want to make a sound card or sound interface. The only sound it will have is a buzzer, but only for troubleshooting. Thr buzzer will just buzz different patterns of sounds so I know if it's an error or something else. And if all that succeeds, there will be a problem. It will (probably) be unable to run any 3rd party software since it is my custom handmade cpu architecture, custom instruction set, custom firmware and OS. Everything will be custom. And probably the only software it could run is the one that I make specifically for it. Maybe, but just maybe if I "steal" already existing architecture such as intel x86 processors and even flash firmware like coreboot or libreboot. Then it could maybe run 3rd party software. If I actually "steal" (copy) the existing architecture then I'll first try booting linux on it. But my primary goal is to make my own os for my own architecture.

[eternal sorrel]

Yeah why not 67 is greater than one or however the saying goes

[eternal sorrel]

Sounds like a lot of work 😋 and i love that

[balmy dirge]

Oh. That could be interesting and complicated. I first have to tidy some things up in life before making a whole community

[balmy dirge]

it is a huge amount of work! The whole project could take me years. Mostly because of material gathering and software development at the end. Assembling the circuit could take me just a couple weeks or one month. Which is very fast for such project

First I have to get the parts. Mostly ICs, wires, cables, many breadboards for prototyping and troubleshooting. That could take me months to collect all that. For example to build a 64 bit ALU (Arithmetic Logic Unit, idk if I spelt it right), it would need around 256 ICs with logic gates. Very impractical, so I could decrease the amount by using more complex ICs. So the amount could go down from 256 chips to around 50 or 30.
But that's just the ALU, let's not forget the rest of the CPU and the custom motherboard including the connectors for PS/2 keyboard and perhaps mouse.

[eternal sorrel]

Yeah fair enough.. well keep me updated with the whole thing

[balmy dirge]

If I ever make the community you can join if you want, and get updated

[eternal sorrel]

So much bigs words for my small brain

[balmy dirge]

Long story short. I'll need many things.

[unkempt hawk]

Hi guys

[normal galleon]

hi

[brisk zodiac]

who wanted to make a bci

[bold drift]

hi guys im here new to learn python

[ripe wigeon]

Guys I am new into programming and interested in all the robotics and stuff, what do you recommend should I just start programming an Arduino or wait a bit?

[noble wedge]

Learn the basics of python: functions, data types, loops, etc., and then try some basic projects like controlling LEDs, follow some tutorials, and when you have a basic understanding of all those things, try making your own project. When doing your own project, you probably will run into some problems, but you really learn a lot from errors.

Just don't give up!

Raspberrypi.org has some great tutorials: https://projects.raspberrypi.org/en

Adafruit has lots of good tutorials too: https://learn.adafruit.com

[supple vault]

Welcome!

[tidal haven]

Could get some cheap hobby servo motors to play with too, a little while ago i bought a cheap 6 DoF robot arm, that uses cheap servos, so it's not very precise, but pretty fun (i drove it via a Pi and I2C servo driver)

[ripe wigeon]

Aren't Pi(s) very expensive tho?

[zenith niche]

I want to send 3v or 5v signals from something connected to usb port controlled by python. What's the easiest way to do this?

[tidal haven]

you don't have to use a pi, can easily drive a servo via a microcontroller

[zenith niche]

OK cool could you please suggest a microcontroller that works well with python?

[tidal haven]

i used a raspberry pi pico recently, for driving stepper motors, via micropython and the PIO support

should work fine for servos too

[zenith niche]

ah right, thank you. I was after something that works with full Python. Perhaps I'm asking in the wrong place? Just want something that plugs into a normal USB port and sends signals to various pins Python instructs

[tidal haven]

Not exactly sure what you're trying to control, but you can use an FTDI chip attached to the USB port to set pin states, looks like Adafruit provide some python libraries to interface with these chips too - https://www.adafruit.com/product/2264

Or you can use a microcontroller with usb support and run a program on it that takes serial input, and sets pin according to certain serial commands

[elfin sphinx]

arduino with the pyfirmata library

how it will work is , there will be a python script running on your PC that will control the arduino connected to the USB port , you can set its pins do whatever you want

the drawback is that , the code that tells arduino what to do lives on your PC , not on the arduino (because arduino doesnt support python) , so whenever you unplug or shut off your PC , the code also stops.

but if you are looking for something that just stays connected to your PC all the time and you want it to work when its connected, a simple arduino bboard with pyfirmata is probably good enough

[zenith niche]

Beautiful tyvm. This is exactly what I'm after.

I am specifically trying to control several relays and in the meantime I've ordered this, https://www.aliexpress.com/item/1005007822223114.html , expecting this would simplify the hardware esp wrt wiring

The problem now is that I have no idea how I'll control this thing. Maybe this? https://github.com/Brasme/usb_ch340_4x_relay_control . I'll have a tinker with it when it arrives

[elfin sphinx]

yeah what you linked seems fine

but that module looks more like "plug it directly into PC and control it with code" , rather than "connect it to a microcontroller and code the microcontroller to talk to it" , but you can do it if you want to , its just like , taking 4 steps to solve a 2 step problem

i would have recommended an arduino with a relay module , much cheaper and you will find tons and tons of wiring guides / tutorials about it on internet

[brisk zodiac]

guys i now how to make a bci now

you can probably use ta the serial library to read cmds that u can code in cpp

yes

[elfin sphinx]

what is going wrong ? what do you need help with ?

im not sure , ill check when im back , im not familiar with the timing functions and how they work

like , afaik , the us sleep is probably not accurate and so on

[grand path]

esp 32

[woeful parrot]

Absolutely, so basically, i've done some research and found out that i bought the rasberry pi without integrated headers! Isn't that fabulous? Anyways, because of the lack of the headers, it renders the rasberry pi useless..

And i was just wondering if there is any way i can do something with it

[brisk zodiac]

wow

[brisk zodiac]

solder

[woeful parrot]

I have absolutely no idea how to solder and unfortunately i dont have a solder in possesion..

so yeah i might aswell stick to the arduino uno lol

[brisk zodiac]

dosent just inseritng the wires and like like twist them to fix it in place

[woeful parrot]

Oh is that possible?

[brisk zodiac]

i think so

but just see if its like touching the golden color points

[woeful parrot]

yeah, i got it

thank you so much, you might've just saved me 20 euros or som

[brisk zodiac]

is it working

@woeful parrot

[woeful parrot]

i will try it another time cause ive got h/w

hi, Im trying to make device like the elegoo streamdeck. I managed to send data via bluetooth with my esp 32-wroom to my pc. I made a python script that checks if the pc is connected with a device with a certain device ID and if yes it gets the port and waits for data to arrive. everything works but I got one weird problem. Im running windows 11 on my pc and when im running the script, and the esp is connected every hour or so, my usb devices fail for like 10 seconds. so I cant use my mouse and my headset disconnects. I looked in the event viewer for errors and actually found something related to my issue. it always pops up after the usb "fail". BTHUSB event: 18. if you know anything plsss tell me, im ging insane. heres my python code btw :
