#

Did you push a button?

balmy osprey
#

but theyre not synced with me pushing the buttons

eager wasp
#

Or is it just random.

balmy osprey
#

random

eager wasp
#

Okay... so likely the input pin is "floating"

#

So just randomly like triggers.

balmy osprey
#

floating, i see

eager wasp
#

because it's not connected to ground.

#

Your switch is either 0V or 3.3V right?

balmy osprey
#

Yes

eager wasp
#

The pin you're listening on is unknown.

#

So that probably means your ISR is working okay.

balmy osprey
#

Ive used GPIO 34

eager wasp
#

Did the switch help?

balmy osprey
#

That seemed to be correct

eager wasp
#

Okay...

balmy osprey
#

Let me try another pin for input

eager wasp
#

Okay....

balmy osprey
#

For some reason, switching to pin D5 or GPIO 5 didn't help

#

No new boxes though

eager wasp
#

What's on pin8/IO32/GPIO32?

balmy osprey
#

D32 is empty

eager wasp
#

Try D32.

balmy osprey
#

its not making new boxes

eager wasp
#

Did you try both "8" and "32"

balmy osprey
#

okay it srated making boxes again, there was a small typo, but random boxes

eager wasp
#

On push?

#

Or just random?

balmy osprey
#

on boot

#

random, but just a few, and then it stops

#

button is unresponsive

#

is that because the for lop has ended?

#

loop*

eager wasp
#

After 15 seconds it would.

#

If you set the range(1500) to 3000 it should go 30 seconds.

balmy osprey
#

i set a range for 8400

#

but nothing when i press the button

eager wasp
#

You can try touching the pins with your fingers to try to trigger it.

#

Or you can try touching a wire connected to +5V to the GPIO pins to see if you can trigger it.

#

Isn't GPIO2 connected to the LED?

balmy osprey
#

let me check

eager wasp
#

Your switch circuit looks correct.

#

I think at this point it's just a matter of finding the right pin in your esp32.

balmy osprey
#

its behaving really weirdly

#

i changed the input object name string to "B"

#

but the screen shows A for a long time after i upload boot.py

eager wasp
#

a = box(10,10,10,"A")

balmy osprey
#

yes

eager wasp
#

You have that at the bottom, right?

balmy osprey
#

yeah, just to show that the screen is on

#

a = box(10,10,10,"WWWW")

#

but when i change it to this, it still shows A on the screen

#

its in some kind of loop, unable to restart the backend

eager wasp
#

power off...?

balmy osprey
#

yeah..

#

restarts with an A

eager wasp
#

probably didn't upload your code.

#

Not you...

#

but the esp32 didn't accept it.

balmy osprey
#

it's still not eating the code

#

dafuq, it's like the A is burned in there

eager wasp
#

You have to wait like 84 seconds.

#

You basically have to get out of that loop.

balmy osprey
#

haha i changed it back to 1000

#

youre right

eager wasp
#

I have a suspicion it's just trying to find a pin that works.

balmy osprey
#

let me upload a video of this, maybe you'll see how bizarre this is for me

eager wasp
#

You have a button on your little esp32 board right?

balmy osprey
#

yeah theres a button there PRG

#

sorry, EN

#

its says

#

does that mean that Pin EN is the output of the button?

eager wasp
#

Well.. EN is the reset button...

#

I was looking to see if the boot button is wired up to a pin on the esp32.

balmy osprey
#

Theres BOOT and EN

#

It's so weird, if i fiddle with PIN32's wires, it makes new boxes

#

but that A still appears

#

for some reason

eager wasp
#

The last line of code...

balmy osprey
#

i changed it, it doesnt exist anymore

#

but it does

eager wasp
#

Hmmm

balmy osprey
#

Ah okay, i saw the problem an d fixed it

#

i called t once earlier

eager wasp
#

So pin32 is the right pin.

balmy osprey
#

Okay, so the input works, because now this is happening

#

But it's bouncy af

eager wasp
#

Right... the ISR is triggering all over the place.

balmy osprey
#

should i add a capacitor?

eager wasp
#

Can you post your code?

eager wasp
#

Button still does nothing right?

balmy osprey
#

Hard to say because the moment i connect it, it starts making random boxes

#

the pin works for sure

eager wasp
#

It's bouncing.

#

Well... wait.

balmy osprey
#

thats weird, now it suddenly doesnt work

eager wasp
#

So ... you might be having an issue with bouncing.

#

If that's the case you can probably set the delay in your main loop to .1 s

#

But your ISR is definitely triggering.

#

Pin.IRQ_HIGH_LEVEL interrupt on high level.

#

Also use PIN.IRQ_HIGH_LEVEL.

balmy osprey
#

whoa

#

lemme try

eager wasp
#

The switch is noisy. So yeah a capacitor will help... But if you want to do it in software you may have to keep a state somehow of when it's on, and when it's off.

balmy osprey
#

high level didnt work

#

now i get nothing

eager wasp
#

5 * R * C could be .1S.

#

I think you're getting closer...

balmy osprey
eager wasp
#

So you have a pull down resistor, right?

#

at the switch.

balmy osprey
#

Yeah, i just picked one I'd used earlier

eager wasp
#

So ... what's the value of that? 3300?

balmy osprey
#

should I choose a different one?

#

๐Ÿ˜… I just use the labels on the bag

#

this was a random one

eager wasp
#

Well... so uh... well...

#

1k - 10k.

#

lol

balmy osprey
#

hahah okay one second

#

got some 1Ks

eager wasp
#

If you put a 20 microfarad cap in ...

#

parallel to the resistor.

#

5 ( 1000 ohm ) * .00002 farad -> ~.1S rise time/fall time.

balmy osprey
#

the 1k resistor worked! Had to change back to _IS_Rising though

eager wasp
#

Yes.

balmy osprey
#

let me add the capacitor and see if bounciness reduces

#

hehe bounciness

eager wasp
#

10microfarad might work... anything in that neighborhood.

#

The rc/cap combination should stop the switch from bouncing.

balmy osprey
#

got a 10uf

#

lemme see

#

capacitors are directional? sorry, I was a mechanical engineer

eager wasp
#

Only electrolytics.

#

The minus should be labeled with the white stripe.

#

That goes to ground.

balmy osprey
#

ah okay right

eager wasp
#

You can do the debouncing in software but frankly hardware is easier.

balmy osprey
#

So, its doing this weird thing where, if i push the button down then nothing happens but if I remove the wire connecting the button to the e32 pin, it creates new boxes

eager wasp
#

Hmmmmm.

balmy osprey
#

and every time i touch the wire to the breadboard, a new box appears

#

and this is on the end of the D32pin

eager wasp
#

Is your switch wired up correctly?

balmy osprey
eager wasp
#

In the picture, does the switch connect left to right or top to bottom?

balmy osprey
#

this is the switch flipped

#

exactly as it was on the previous picture but upside down

eager wasp
#

That doesn't help me. ๐Ÿ™‚

balmy osprey
#

oops!

#

how do i find out?

#

i have a multimeter

eager wasp
#

Put the 3.3V line on... the pin directly opposite of the resistor.

#

Seems like you're super close.

balmy osprey
#

You mean the pin thats powering the screen?

eager wasp
#

Yeah....

balmy osprey
eager wasp
#

But ... I believe the software works for the most part now.

balmy osprey
#

and the switch works, just tested with the multimeter

eager wasp
#

okay... so check the voltages going into the switch.

#

when the switch is open (not pressed) make sure there's 3.3v across it ...

balmy osprey
#

4.7 v from the screen voltage (the new pin that you just reccomended) and 3.2 from the previous one

eager wasp
#

just needs to be 3.3v

#

So use the previous pin.

balmy osprey
#

the original pin was 3.2 ish

eager wasp
#

Then when you push the switch, the voltage should drop to 0.

#

You can also measure the pin on the esp32 circuit (if you have enough hands.)

main ridge
#

anyone can help with a frequency meter electrical schematic?

eager wasp
#

Basically when that switch closes, voltage across the switch should drop to 0V and the voltage to GPIO34 should be 3.3v

#

When the switch is open, it should be the reverse.

#

So it could be a bad switch, etc.

balmy osprey
#

the moment i press it, it goes to 0

eager wasp
#

Yay.

#

Okay so measure the voltage across GPIO34 and ground.

#

Make sure when you push the switch, GPIO34 sees 3.3v

balmy osprey
#

So this isn;t happening, when i press the switch theres no change

eager wasp
#

bingo

#

Solve that issue.

#

Okay. I need to go. ๐Ÿ™‚

#

Software is probably fine.

balmy osprey
#

thanks so much Rob!

#

Really, thanks a lot

#

thanks!

balmy osprey
#

guys, if anyone is still checking this out, there seems to be a constant 0.05 - 0.1 volts being read on my GPIO pin 32 on the esp 32

#

For some reason this seems to be throwing off my code because even if the button is pressed, there is no response

#

however if the button is not pressed and i merely touch the button output wire to the breadboard right next to my pin, it registers as an interrupt

#

and even this happens sporadically

#

Let me just upload a video

#

This is the full code

#

I'm putting all this on GitHub so people from the future can benefit

pure sinew
#

Yeah, but I still worry that too many corners have been cut with them causing them to be unsafe ( have a look at some of big clive's videos https://www.youtube.com/user/bigclivedotcom )

Hi, I've got two sadly neglected Raspberry Pi:s B Rev2 from a time where I had yet to type my first line of Python. I mean to rectify this and put them to use but don't know where to start. It was a while ago and I've only used them as desktops for PHP development... It was my first experience with working in the terminal. Now I want to use them with Python, but not as desktops, I've got both a MacBook Pro and WSL2 on WIndows to satisfy my dev environment needs. I want to make something "fun", or useful, without having to buy too much stuff to begin with. The current OS on one card is Wheezy... I remember trying to upgrade to Jessy at the time but it didn't work. So what's the most "Pythonic" use of my Pi:s? :)

Hey guys, I'm working on a microcontroller project where I'm trying to run a physics engine on an esp32. Everything worked fine until i implemented the collision detection. Right now the code compiles but the screen remains blank and I have no idea why.

Could someone take a look and see why it could be broken?

Hello people. I needed some help on how I could send variables from my python program to arduino.
its basically a value that tells the arduino to rotate a stepper a certain number of steps
i've googled some stuff about standardFirmata, pyserial etc but they didnt help much
can anyone please help me out?

errant wigeon
#

Is the arduino connected to the computer running python? If that's the case, while I haven't used pyserial in quite some time that would be the library I'd recommend

shadow ginkgo
#

yes im using a usb cable

#

and it seems to be working now.
ser = serial.Serial("COM8", 9600)
ser.write(itr.encode())

#

sending a variable itr to serial

#

Fantastic and congratulations on getting it working!

hello, is there anyone here that knows how to use pyserial with arduino and can help me in dms with something?

errant wigeon
balmy osprey
#

Guys, does anyone know where I can find the source code for framebuf in micropython?

#

is there a way to modify it or will I have to edit it before flashing my esp32 again?

zealous oyster
# errant wigeon What are you trying to get working?

i made a tic tac toe game in python and i want to connect the Arduino to it and use a joystick in order to play the tic tac toe and i am still not sure how to use the pyserial and didnt understand too much from the internet

compact delta
#

can I program arduino in python??

gentle vapor
#

depends which one, and what you mean by "Arduino" and "program".

  • All arduino boards (boards made by the Arduino company) should support Firmata and let you pilot it through USB by a python script on your computer.
  • Some Arduino boards are supported by Micropython and/or Circuitpython (a python interpreter running on the board).
  • Many other maker-oriented boards that are compatible with the Arduino IDE are supported too
#

I don't know much about frameworks that allow compiling a python-like language for an arduino board, but I think that exists ?

errant wigeon
#

this It's *kind of possible* as long as you use the right arduino board, but it's not the easiest thing in the world in comparison with a board advertised for circuit or micro python

zealous oyster
#

I have a problem with pyserial that it only gets info for about a second when i open the program and then stops getting anything from the arduino, how do i fix this?

errant wigeon
#

Could you post your code? It's hard to even guess what's going on without it. And just as an initial comment, double check that your baudrate is set to the same speed on both ends

zealous oyster
#

the code is pretty long tho

#

do you think you can help me in dms?

errant wigeon
#

Can you post the section that does serial communication? (I've got to step away shortly so posting sections of code here will let others be able to help after I head out as well)

zealous oyster
#

well its a bit complicated

gentle vapor
zealous oyster
#

but i will send anyway maybe u can help

#

this is everything that uses the arduino

#

i am using a joystick with the arduino in order to choose the place in tic tac toe

#

you have a while True in your while True ?

#

you set Left, Click and Right only once before entering the internal while True with values that are not changing inside

errant wigeon
#

The while true inside the while true is entered no matter what, and when there's no assigned button click it can't exit

zealous oyster
#

i dont understand

zealous oyster
#

once in the beginning as false

#

and then in the loop in order for the joystick to make them true

#

well i copy pasted the whole serial into the two while true loops and now it works

#

ty for letting me know the problem was with the while true loops

errant wigeon
#

Did changing the while loop solve your problem?

KeithTheEE ---- i lost a link , oh no ---- I asked you about cubesats , the tiny solenoids , servos , pumps that can go inside -- i want to join that tech to microcontrollers

errant wigeon
#

I'm afk for a bit but more specifically what were you thinking of needing and doing?

steep dune
#

i know python and microcontrollers -- i want to nake a water chemistry analyser , so need to re-route water sample to here and there , expose to different sensors , so it - micro piping , valves , pumps ....................................................

errant wigeon
#

Ok, that's a lot of goals

#

do you have the valves, pumps and sensors? A good place to start would be to make sure you can program a micro controller to use all of them, and then later on you can work to put them together

#

that way you aren't trying to figure out how to build it, and figure out how to toggle a solenoid valve at the same time

#

it makes the learning curve much easier, breaks the problem down into smaller portions, and when you do have a problem, it's easier to isolate so you can ask for help and have a clear question/problem statement for others

Hey guys, I am trying to do the following task with my RPi

  • Button press second time blink LED with 0.5 sec interval
  • Button press third time blink LED with 2 sec interval

Is there any better way to achieve it. ?

#

you could use async to have a run loop and start a new task when the button is pressed, you'll need to do some debouncing though to avoid repeating tasks, and stop the previous task whenever you start a new one

#

or you could manage the timings manually with a bit of comparison to time.time()

brazen meadow
#

You could use a pin change interrupt

This some basic code using async and await. It's written for MicroPython.

from machine import Pin

async def blink(led, period_ms):
    while True:
        led.on()
        await uasyncio.sleep_ms(50)
        led.off()
        await uasyncio.sleep_ms(period_ms)
              
loop = uasyncio.get_event_loop()
loop.create_task(blink(Pin(12, Pin.OUT), 400))
loop.create_task(blink(Pin(13, Pin.OUT), 300))
loop.create_task(blink(Pin(14, Pin.OUT), 500))

try:
    loop.run_forever()
finally:
    loop.close()

asyncio needs to be used instead of uasyncio and the gpio library would need to be changed

Has anyone gotten compiled cython code to run on an MCU? Sadly, no resources online

#

it's on for delay time, then off for delay time, so the total duration of an "animation loop" is 2 * delay hence the %

#

if you want a different duration for on and off you can change timings to a list of tuples like ( None, (0.5, 2) ...) and do something like:

    if delay:
        if timespan % (delay[0] + delay[1]) < delay[0]:
            GPIO.output(ledPin, GPIO.HIGH)
        else:
            GPIO.output(ledPin, GPIO.LOW)

Hey guys is there a way with the python subprocess module to create a subprocess but not actually start it? For example I want to prepare a subprocess to start but not actually run it until later, but my code relies on knowing if the subprocess is running to be able to know if it should start the subprocess, but this is all inside a loop so I can't just start the process when I need it because it's inside a loop it will spin up loads of subprocesses

#

Or perhaps multiprocessing might be a better way, however I've not found how to correctly use multiprocessing with system calls.

Heya everyone. Need a hand with some MicroBit code. Below is my code - when X == 1 the left motor is supposed to spin. When X == 2 the right motor should spin. When X is anything other than 1 or 2 both motors should spin.

I have defined X = 1 and have no motor activity at all. This is using a 4tronix board. There are no errors. the code just doesn't do anything with the motors.

Does anyone have any idea what I've done wrong here? As I said, the microbit throws no errors. It just does... Nothing.

yeah, without anything to indicate if it's a thermal throttle, ram, or processing power issue it's hard to guess where the issue is. You could throw some logging in there to save all of those values into a log file ever so often so you'd get an idea of what the issue could be though

# pure peak defien measure

Ideally hook an oscilloscope. If you don't have one, a voltmeter. You can also try connecting the pin directly to GND.

errant wigeon
# pure peak *define

Another approach would be to divide and conquer. First test the servo code and only the servo code: so you'd change your while loop to go to 90, wait 5 seconds, and -40, wait five seconds, and repeat the loop.

If that isn't jittering. try the trip wire code. If it's high, turn on an LED (write one of the extra pins to high), if it's low, turn it off. If there's a flicker, you know it's the tripwire.

#

I'm inclined to think your problem is the trip wire circuit, but the test will help narrow that down

errant wigeon
# dire rivet Hey, is there a way to program the arduino with python

Not really. There are a couple (the only one I know of is the arduino duo). The issue is simply size: most arduinos just don't have enough memory to house all of the backend needed to make python work. There are other issues as well, but that's the core one. There are a few ways around it, but they're not the cleanest from what I know

do i need R1 or can i just delete it, in other words does the microphone(J1) needs to be connected to 5V?

unknown_1.png

#

@main ridge depends on the microphone.

#

Basicly the mic is going to need some sort of internal bias. C1 is keeping the mic's bias from messing with the op amp.

#

The mic will likely have some sort of internal FET that needs a bias.

#

@main ridge So " R1 or can i just delete it" --> No you need it. "microphone(J1) needs to be connected to 5V" --> Yes.

Fish tanks I know less about

steep dune

well some have tanks with leaks -- it happens when away - so the idea is to moniror then send message to phone

errant wigeon
#

well you can buy cheap sensors but the 'connect to a microcontroller' ones are a bit more expensive

#

leak detection is ... not exactly tougher, but it's a system you want near 100% reliability

well a Raspi can send email and message i guess

what if the router went down and the rpi didn't successfully reconnect, and then there's a leak?

steep dune
#

dead fish - ready for cooking

#

but the goal is always super reliable

errant wigeon
#

For a leak sensor, you want multiple ways it'll signify that there's a leak, lights, sound, and digital messages/email type thing

steep dune
#

well some one asked for a loud alarm , but i also like the idea of text to speech stuff

errant wigeon
#

I'd start with a loud alarm, then later on you can try to add text to speech

#

loud alarms are simpler, and you're trying to do a lot so it's a good idea to get as much working as you can in the most minimal way possible

steep dune
#

i know sensor tech is evolving - doing more

errant wigeon
steep dune
#

cool - 5 sensors for $35 , dont know what they do

Let me take a look--one moment

#

That looks like a good bundle. The ph and ec are great for hydroponics, I have no idea if you'd use an ORP sensor for a home system--aquarium, hydroponic, or aquaponic, but it seems nifty

#

tds should let you know when you need to change filters for you fish tank water filter

#

Turbidity Sensor should do the same I guess?

#

If your setup has a leak, is there an area all the water pools or is it to random to predict where the water will be?

i am using micropython on pico. In the code i am using UART and saving data UART received data in bytes array . I am facing issue while accessing the buffer.
the errors says : IndexError: bytes index out of range.

# velvet pumice Can you show the relevant part of the code? 
from machine import UART, Pin
import time
received = False
uart1 = UART(1, baudrate=9600, tx=Pin(8), rx=Pin(9))

uart0 = UART(0, baudrate=9600, tx=Pin(0), rx=Pin(1))

txData = b'hello world\n\r'
uart1.write(txData)
time.sleep(0.1)
rxData = bytes()

        received = True
    if received == True:
        received = False
        for i in dlist:
            if i == rxData[1]:
            print('Condition is working')
        print(rxData.decode('utf-8'))
velvet pumice
#

I think the problem is the length of rxData

granite shadow
velvet pumice
#

can you try with somethink like

#

rxData = bytearray(10)

granite shadow
velvet pumice
#

Note that bytes() will return a 0-lenght array.

# 
In [15]: x = bytes()

In [16]: len(x)
Out[16]: 0
#

Also, bytes() construct an inmmutable array of bytes.

#

Sorry. Now I see that you are doing rxData += uart1.read(1)

#

So if you get an error when accessing rxData[1], is because you are not getting data from the UART

granite shadow
velvet pumice
#

prining the lenght of the array solved the problem?

I understood the problem and i solved it by checking the lenght.

Some microcontrollers need to run a program and last 10 years on a coin cell battery. A cpu, cannot do that because it's designed for different purposes, such as completing a computation as fast as possible. Speed takes power, so it's not an option in some use cases

Will embedded devices kill computer in the future ?

Microcontrollers are sort of "Do one job and do it well" type devices. Embedded Linux on the other hand is a computer--it can do a lot. It runs a linux kernel so most of what linux is able to do, you can do as well (depending on what peripherals are available).

errant wigeon
# boreal creek Will embedded devices kill computer in the future ?

No, but there probably will be more microcontrollers and more computers in the future. There are more and more locations where we can add behavior to a device, and some behaviors require a micro to make it happen and handle the 'when to do' and 'what to do in what order' steps. A lot of those micros will look to a computer to help see the conditions, and then they'll execute their task

boreal creek
#

Like work together ?

errant wigeon
#

yup. It's a solid design. I can make a block that runs some lights, but the decision of when to turn them on or off can be left to a computer (that sets up a webpage for me to interact with)
The micro handles the colors, timing, and changes, while the computer handles everything tied to the internet and real time clock based logic.

#

In a tesla, the main computer manages everything, but a micro handles the "make a door handle pop out or in" functions

boreal creek
#

Like one is controll physical part ,one is controll non physical part right ?

errant wigeon
#

I don't quite get that question, I'm sorry

boreal creek
#

I mean computer controll non physic things and miccro controll physic things

#

? Is that what u mean

errant wigeon
#

That is a way to set it up, yes

#

I'm also doing a really poor job of explaining this, so if you're confused, don't worry it's probably my fault

boreal creek
#

No no that's okay

#

So

#

In what case

#

U think computer ( smartphone/personal computer ) is better than micro

errant wigeon
#

I would choose a computer over a microcontroller if

  1. I have more money (there are a lot of added parts to a computer than a micro, so it usually is a more expensive choice

  2. I don't need to worry about power (computers can eat it up)

  3. I'm under time constraints and I need to ship a version of the product as fast as possible (Linux is fairly stable, my program might not be. By using embedded linux I can present a version of the product without spending time on developing it's operating system)

#

There are other reasons of course, like if I need a lot of computing power and I'm not good with FPGAs (another different for of hardware, which are actually kind of hard to use at first. They've got a steep learning curve)

#

I think another reason I'd use a computer is if it interacts with the internet or if I have to do a lot of programs at the same time. A micro controller doesn't really have threading, and networking is complex. Computers have it down so it make sense to start with a solution that works

boreal creek
#

because as we see nowadays, traditional calculator is really good but you wont see many people use cal but smartphone instead, gps also, camera or dictionary devices

#

So that's why i have this question, because a gps is really good a real professional camera have a better picture but like computer are dominating and replacing those things nowadays

errant wigeon
#

I think that is more of a byproduct that people always have their phones ready, usually charged, and with them

#

But there are probably hundreds of microcontrollers you interact with on a daily basis, and they do their job well and you don't notice they're there

#

Does a button light up on an elevator? There's a microcontroller telling it when to light up and when not to. Smoke Detectors have micros, unless it's an old variety, so does your thermostat.

#

Phones are taking over a lot of devices because they can conveniently do many things. But there are many tasks which don't need to handle a lot at once built into the world around you, and that's a huge home for microcontrollers

boreal creek
#

Ok got it

#

So which is the most impact to ourr world ?

errant wigeon
#

In python, does a library or function have more impact?

boreal creek
#

I dont know i'm new to computer science

errant wigeon
#

They're both important, and they have grown so they're tied together

boreal creek
#

Ah got it

errant wigeon
#

Yup! They're all tools, you pick the one that's best suited for the job, and sometimes that means you use some combination of both of them. A car has so many microcontrollers and computers in it. Just because each one is the best solution for the task at hand

#

Just like how python isn't always the right programming language to use. You pick the best you can to the constraints you have.

boreal creek
#

Ok got it thank you

#

Do you thinking in somesday, we have all we need and we have nothing to develop because like we have software to do all things ?

tardy heath
#

I have a raspberry pi pico and i am trying to read the serial data from it
this is the code i have so far but it doesnt really work. Does somebody know a way to read the serial?

import serial, time

s = serial.Serial('COM5', 9600, timeout=1)
while True:
    a = s.read(10)
    if a != s.read(10):
        a = s.read(10)
        print(a.decode('utf8').strip())
    time.sleep(0.1)
errant wigeon
errant wigeon
#

and is this the code running on the pc?

tardy heath
#

yes and yes

#

i have this running on the pico

from machine import Pin
import time

led = Pin(25, Pin.OUT)

def on():
    led.value(1)

def off():
    led.value(0)
    
while True:
    print('test')
    time.sleep(0.5)
errant wigeon
#

Ok, what computer are you using?

tardy heath
#

windows 10

errant wigeon
#

Mac, windows, linux

#

Awesome, give me a bit to google

tardy heath
#

ok ty

errant wigeon
#

I want to see if the port is wrong

tardy heath
#

its the write port

#

i know that

errant wigeon
#

Ok cool, do you have the arduino ide installed?

tardy heath
#

no but i can get it

#

i have thonny rn

#

and i am running micropython on pico

errant wigeon
#

Ok, I think Thonny should have what I want, give me another moment to google (I'm just going through a mental checklist of lowest hanging fruit by the way)

tardy heath
#

ok wait

#

i just realized

#

i am reading the data

#

i want to write the data to serial

#

and have the pico pick it up

#

i was doing it backwards

#

is that possible to do?

errant wigeon
#

oh awesome! ok that solves a lot of issues at once

errant wigeon
tardy heath
#

well how do i like read it on the pico

#

that is the main problem

errant wigeon
#

Before I get to that--I think the default baudrate isn't 9600, let me validate that though

tardy heath
#

oh ok

errant wigeon
#

I think you need to set it to 115200

#

Are you using circuit/micropython on it?

tardy heath
#

micro

boreal creek
errant wigeon
tardy heath
#

yes

errant wigeon
tardy heath
#

how do i install a library to the pico on micropython

errant wigeon
#

Is it not a builtin library?

tardy heath
#

idk

errant wigeon
#

I think it's a builtin, try just importing it like that

tardy heath
errant wigeon
#

hmmm

#

Ok, can you give me about 40 min? I have one and I'll try to set this up and get it running, and walk you through it while I do. I haven't played with the pico yet, and I'm use to circuit python over micropython for the time being (flip of the coin, they're both great projects) so I need to flash micro back onto mine

tardy heath
#

alright sure

errant wigeon
#

I'll ping you as I go through, so it should be complete radio silence

tardy heath
#

btw i have to use micropython

errant wigeon
errant wigeon
# boreal creek Nice!, do you think problem will create a new problem ?

As much as any new technology creates problems. But while it's good to be mindful of the consequences of actions, I feel the benefits generally are positive. I'm going to focus on the current question for a while though, so I'll be 'afk' from this thread. Feel free to ask more questions though! I'm just going to focus on the pico problem

errant wigeon
tardy heath
#

yes

errant wigeon
#

which version of micropython are you running?

tardy heath
boreal creek
errant wigeon
tardy heath
#

the second one i think

errant wigeon
#

Ok cool, I'll try that (I'm having my own host of tech issues because of course I can't just help you solve you're problem ๐Ÿ˜› )

tardy heath
#

dont worry your already going out of your way to help

errant wigeon
#

Ok, so for the moment I'm unable to get it to install micropython, I've tried the stable version, and the pimoroni version and it refuses to boot back up after flashing

#

I'm going to try the nightly next and if that doesn't work I'll try a second pico (I have three but you know what they say about 3's and strikes..)

tardy heath
#

alright

#

i need the pimoroni version

#

unless there is a way to get pimoroni libraries installed on micropython

errant wigeon
#

If I'm right, (knowing pimoroni) it's just a bundle so every added feature is provided--that way you don't have to download much. My issue should impact you, I'm just trying to get this running so we're as in sync as possible

#

as long as your pico shows up as micropython/ or pimoroni you're fine

#

And Neradoc if you've got an answer and see this--go for it. I'm just trying to get my boards in order. Skipping my personal trouble shooting is great ๐Ÿ˜„

#

Ok just tried the nightly build, micropython didn't like it. No idea why. Let me grab another pico

#

I'm curious. If you've got blinka installed, I might be able to cheat. So if I can't get a pico working all's not lost

#

ohh... hmmm... I'll have to ask someone about this. It's working as micropython, but it's not showing up like circuit python does.

#

I just don't know enough about micropython.

gentle vapor
#

what ?

errant wigeon
# gentle vapor what ?

Hi, we've got a (in theory) simple question if you've got time. I've got new questions now, but those are less important. Do you have a minute?

gentle vapor
#

sure

errant wigeon
#

Sweet, we've got a pico running pimoroni's version of micropython with blinka packages included. @tardy heath wants to (from the pc) send text via serial, and read it on the pico

#

I figured I'd flash a pico with that build and have an answer quick, but I don't, and I know you're somewhat familiar with the pico.

gentle vapor
#

ok, so far I have Micropython installed and running

#

(the pimoroni one)

errant wigeon
#

Sweet, the python code for serial communication should be,


myport = 'COM5'
baudrate = 9600
s = serial.Serial(myport, baudrate, timeout=1)

s.write(0xFF) # just to know what was written
#

probably should throw a delay at the top for making sure everything is setup

errant wigeon
#

(this is a question for my own understanding)

gentle vapor
#

like a drive ? no

errant wigeon
#

ahhh that was my mistake then! Thank you

gentle vapor
#

Micropython only does that on the pyboard as far as I know, it is a little puzzling that they don't implement it on the pico to be honnest, but I don't know

errant wigeon
#

Huh. Oh well, I can see their reasoning--a $4 board is cheap and optimizing everything in it is worthwhile

gentle vapor
#

here is the kind of test script I have on the PC side:

import serial, time
import argparse

parser = argparse.ArgumentParser()
parser.add_argument("port", type=str, help="Serial port of the board", nargs=1)
args = parser.parse_args()
port = args.port

s = serial.Serial(args.port[0])
s.timeout = 0.05

while True:
    if s.in_waiting:
        incoming = s.readline().decode("utf8").strip()
        print(f"Incoming: `{incoming}`")
    time.sleep(0.1)
#

(the argparse part is very useful since serial ports can change from board to board or on windows sometimes even on unplugging and replugging, and it's annoying to have to edit the file for that)

errant wigeon
#

I think on the pc side we're aiming to serial.write("string") though?

#

(And correct me if I'm wrong, do we want to default to baudrate, or make it explicit--I think explicit is better during debugging?)

tardy heath
gentle vapor
#

well then you want to write to the serial and on the board it's simpler to use a stream API with sys.stdin.read() I think in Micropython, and readline and such

#

note that you should manually append "\r\n" to your writes to use readline on the other side

errant wigeon
gentle vapor
#

I don't know much about serial in Micropython though, what is the best way to use it and such

errant wigeon
#

So on the pc, we use s.write('0xFF'), then the pico runs,

While True:
    print(sys.stdin.read())
    time.sleep(0.1)

then?

gentle vapor
#

I don't know, it's blocking apparently

errant wigeon
#

hmmm.. @tardy heath I thought I'd be able to knock this problem out pretty quickly, but I need more experience with micropython. I'm going to try working through it tomorrow, mind if I ping you then when I have a working demo?

tardy heath
#

yeah sure no problem

errant wigeon
#

Awesome, sorry I couldn't get the answer faster but I'll make sure I either can solve it, or point you towards a forum/person who can

gentle vapor
#

note: disabling ctrl-C is not a good idea, I don't even know how you would upload a new code with that running ! alyekScare

#

here is a sample code:

from machine import Pin
import time
import micropython
import select
import sys

led = Pin(25, Pin.OUT)

def on():
    led.value(1)

def off():
    led.value(0)

# don't disable ctrl-C, or how will you even upload new files ?
# micropython.kbd_intr(-1)

while True:
    while sys.stdin in select.select([sys.stdin], [], [], 0)[0]:
        ch = sys.stdin.readline()
        print("CH:",ch)
        if ch.strip() == "on":
            on()
        if ch.strip() == "off":
            off()

put it in main.py and connect to the REPL or run it from Mu, Thonny or whatever, then type on+return or off+return to change the LED

#

(I use readline here, which is blocking, but select makes sure we only go there when there is something available on the serial, so always send lines and that sample code can be generalised)

errant wigeon
#

This is really clean, thank you!

gentle vapor
#

I like to use json to communicate data between the host and the board, though it has some overhead it avoids sending binary data (which could send ctrl-C to the REPL) while allowing for structured data easy to convert in one function call on both sides

I have a question about like electric devices like gps, who make the navigation calculator ?

I'm not that sure what you mean by this. There are teams of people who work on all levels, and you can focus on whatever you're most comfortable or interested in

A raspberry pi is a device called an embedded linux device. It's different from a micro controller in a few ways, namely that it runs an operating system--in this case a linux kernel. There's more info here: https://jaycarlson.net/embedded-linux/ and it spans the whole build process of building an embedded linux device from the ground up

Ok. I just got back from vacation and am catching up on everything, so I'll take a look at it soon (just the usual behind the ball stuff needs to be addressed first).

Do you get an error or anything when trying to run the sample code?

tardy heath
#

no

#

no error

#

just it doesnt detect it

heady oriole
#

Thanks @tardy heath

errant wigeon
# tardy heath just it doesnt detect it

Hmm. Ok I'll see if I can get it running on my machine. If it's not throwing an error and not detecting, I feel like there might be a baudrate mismatch between the two programs. I'll see if I can get it running in a way to duplicate it

tardy heath
#

like im not sure if its not detecting it

#

but when i run it

#

it just does nothng

errant wigeon
#

Do you happen to have a spare LED nearby, so 'when you receive a character' you can blink it on the pico? that way you have an 'on device' indicator.

tardy heath
errant wigeon
#

Just completely blanked that it was there

tardy heath
#

my led is working

#

im confused

#

my led works

#

just the program doesnt work

#

i just had an idea

#

it prob wont work

#

but could u do input() on the pico?

#

and then it would work?

errant wigeon
#

I don't actually know the answer

#

So only one way to find it out! Give it a shot!

#

Can you tell me your debugger setup to write code on the pico?

tardy heath
#

oh

#

i use thonny

#

btw

#

the input() doesnt seem to be working

errant wigeon
#

Awesome! Thank you

#

and bummer, but that's how it goes

#

ok, can you recap to me what code you have running on the pc, and the code you have running on the pico?

tardy heath
#

import serial, time

s = serial.Serial('COM5', 9600, timeout=1)
while True:
s.write('on'.encode('utf8'))
time.sleep(1)
s.write('off'.encode('utf8'))

#

thats on pc

#

from machine import Pin
import time
import micropython
import select
import sys

led = Pin(25, Pin.OUT)

def toggle():
led.toggle()

don't disable ctrl-C, or how will you even upload new files ?

micropython.kbd_intr(-1)

while True:
ch = input()
if not ch:
toggle()

#

thats the new thing ive been testing on pico

# 
from machine import Pin
import time
import micropython
import select
import sys

led = Pin(25, Pin.OUT)

def on():
    led.value(1)

def off():
    led.value(0)

# don't disable ctrl-C, or how will you even upload new files ?
# micropython.kbd_intr(-1)

while True:
    while sys.stdin in select.select([sys.stdin], [], [], 0)[0]:
        ch = sys.stdin.readline()
        print("CH:",ch)
        if ch.strip() == "on":
            on()
        if ch.strip() == "off":
            off()```
#

thats the original script

#

that the other guy sent

#

i was also thinking

#

is it possible to have a script on the pc that would edit a txt file on the pico and then the pico takes the stuff in the file as input to turn on the led?

errant wigeon
#

Plausibly, but I think that's adding more complexity and round-about-ness than you should. I'd rather just get the serial communication working correctly

tardy heath
#

have you had any luck wwith settting it up?

errant wigeon
#

Still catching up on emails, I've been asking questions of you so I can 'just go' as soon as I can focus on it

tardy heath
#

Alright np

#

You can add gear(box)es to any kind of motor, stepper or not. It all depends on what speed, torque, etc you need and also has other effects like backlash

Hey, do you know any discord servers about microcontrollers and stuff? I want to make something like a programmable calculator but I know that #microcontrollers isn't exactly the right place as my questions aren't about python (pls ping me)

Where should I learn Raspberry Pi from?

One of my friends wants to hook up a mc of some sort to his car, so when it turns on it'll play a startup song before bluetooth kicks over.
1: does micropython have support for a teensy 4.0 and audio shield?
2: do you guys think I'd be able to just hard-wire it before the amp and have it work?

Hello. I'm beginner lvl Python and Raspberry Pi user. And I would like to play around with some stepper motors. Can any of you please help me with finding a controller, a stepper motor and a guide to use it. Thank you.

#

P.S. All I have been able to find on the internet is guides and parts for arduino

#

as for guide, I suggest you try using stepper motor library and try and error yourself, because some doesn't support multi motors

Hey guy i'm confused about different between SoC, microcontroller, microprossessor. Anyome tells me more detail ?

# boreal creek Hey guy i'm confused about different between SoC, microcontroller, microprossess...

Soc - System on chip it is a device that contains basically everything of a computer in one chip example apples m1 chip has a Soc design these are generally more expensive than microcontrollers but have better specs
Microcontroller - again a computer in a small space it has less ram and stuff than the soc and hence is cheaper
Microprossors - basically your cpu its only the brain of a computer and things like ram are external.

So why we have SoC and also Desktop, why dont we emerge them and use only one of them for all projects or all purpose because they're doing things the same ?

There's a competition in my region to make a basic self driving car and It got me interested and so I was wondering how I could get started with microcontrollers and computer vision (with modules like OpenCV) on python. I was planning on using a raspberry pi with an arduino kit and a basic camera for the project.

#

I've got ample time for this project but I'd love to get started right away so if anyone has a good websites I could learn from or youtube videos I could watch that would be great :)

#

(also, I've noticed there's a lot of videos on how to do similar things on languages like C++, so would it be wise to use that over python?)

#

so, we're just working on https://pypi.org/project/justuse and were wondering if it would be of use to people with limited hardware if you could load whl (zip) packages directly via tmpfs mount without extracting to disk first

PyPI
justuse

A beautiful, simple and explicit way to import modules in Python with advanced features.

#

are there any limitations beside RAM that should be considered?

#

the idea would be to use fuze-zip from inside the code to mount the zip read-only and import things directly without writing and reading back and forth

# boreal creek Thank you! Nice explaination ,and in which case, we will use SoC or Microprocess...

Soc- they are typically used in mobile phones since you know there they need more ram and stuff without actually going to the a special ram slot
you can understand all from a computer perspective imagine there is a pc in front of you you know that the pc deign is such that the cpu is in the middle and things like ram and storage are far away in a case of a pc you can have better specs and faster computation but with very high price in a soc however since they are all cramped together there they can be accessed faster also soc has less battery consumption
microprocessor - its literally just a cpu nothing else you know right there is usually one single cpu in a pc yup its that

#

microcontrollers - It is used in you household items example oven fridges toaster microwave and stuff since SOC and a whole pc cost so much it isn't smart to have a whole pc on these things which so high price and faster computation which it does not need there are microcontroller these are very similar to SOC but the difference is the cost since you know on top of the everything about a toaster you cant just add a price of a phone with embedding a soc sooo hence they use microcontrollers. They are programmable cips and a machine that is very tiny

#

usage of all-
soc - in phones and sutff
microprocessor/cpu - well in computer systems its the brains of a pc and actual computer
microcontroller - in things like fridges where other cips seem kind of unnecessary and which drives the cost down

#

I hope it helps

Hi all - might not be the right place, but im looking for info on things like hdmi hardware and other video/audio output standards i can mess about with in python - any idea where to start?

hallow igloo
#

I'm not sure python is the best route for this. I honestly have no idea there probably are libraries out there that can do what you want.

#

However I will say ffmpeg is a great tool for taking and sending audio and video data.

#

And it interfaces well with python.

Does anyone knows how I can measure current using micropython ?

Board: Esp32S (NodeMCU)
Current sensor: ACS712 30a
Current: AC
#

Like did a code using Arduino IDE the lib that I had to use was a modified EmonLib, but I'd like to use micropython. So I search for a Emonlib.py and I found one, but seems to don't work like the EmonLib for C. Like the function calc_current_rms returns only the same value for each number_samples arg.

Emonlib.py

LCDs like that can't be read in the dark, but don't need backlight to be read in the light, and use less power. I'm actually looking for a good large one to use as a bedroom clock that would not illuminate the room. I mostly find stuff like:

Hey, i want to get started with micropython on ESP32 CAM board, i dont know where to begi, i found some pages telling to make own firmware, some said to download bin files from micropython site. Im a complete noob to this. Can someone show me the right path

Haven't got it going

cosmic spoke
#

ok

brazen meadow
#

I may end up using esp-idf and C

cosmic spoke
brazen meadow
#

I have an esp-eye which may be why it didn't work

#

Got a couple esp-cam on the way which I'll try

maybe my os is having issues, with extensions on vs code. Once tried to install platform io on vscode and i couldnt find extension.

That's annoying

#

I want to develop a IoT application for collecting sensor values, i want to make it using python. Should i use python or use C in arduino to code thats my major issue

brazen meadow
#

MicroPython would work

cosmic spoke
#

So how does it work , is it like flashing a firmware and moving our .py code or something else

brazen meadow
#

Flash the firmware, copy the files over

#

I use Thonny and ampy

Ok

#

are you on linux or windows

Linux

I have just just stuck with ubuntu as it is easier

Is python just as efficient as C when it comes to micro processors

cosmic tinsel
#

how to check which micropython version i'm running?

#

if i do

import sys
sys.version```
#

it will give me 3.4.0

#

but that's python version

#

i don't have os module as well

brazen meadow
gentle vapor
cosmic tinsel
#

thx

#

no uos :(

#

what's the difference between this version?

#

python and micropython

#

why is there two version

#

3.4.0 and 1.11.0

brazen meadow
cosmic tinsel
#

ye but

#

why would it show python version as well?

brazen meadow
#

3.4.0 is the Python version 1.11.0 is the firmware version

cosmic tinsel
#

if i have to describe which version i'm running the code on

gentle vapor
#

yeah it's the python version it's based one, that property is probably there for compatibility with code expecting a certain version of python to some extent, but Micropython includes stuff from later versions of python, so I don't know that it's super useful

cosmic tinsel
#

how do i describe it?

#

The program is running on Python 3.4.0, implementation is MicroPython 1.11.0?

gentle vapor
#

what board is it ?

cosmic tinsel
#

idk but it's running on arm

brazen meadow
#

3.4.0 is the base, stuff has been added on top

#

The firmware version is the important part

gentle vapor
#

I don't know the Micropython ecosystem too well, not having os or uos is super weird to me
