using 11 is not working?

wide shadow
#

It is now. I was under the assumption it was D11, but that didn't work

leaden walrus
#

yep, in arduino, it's just the integer number

Goodday everyone, I have a problem with arduino and I dont know what to do anymore. When I try to upload to any board beside arduino uno test board it doesnt work. I want to upload coding to a pro trinket, nano board, or feather it all doesnt work because I always get the notification that it cant find the board. I tried diffrent cables, diffrent libraries, diffrent ports, diffrent board settings, and ofc pressing the button a 100 times on the trinket and I'm lost. if anyone could help or have an idea I would love to hear it. Kind regards Dobi.

no, its in com 3 and only com 4 and 5 are visible in the menu, but when I use the arduino uno the com 3 does show.

north stream
#

How do you know it's in com 3? Normally when you plug in a different device, it shows up on a different port.

balmy crow
#

I tried all the coms but never worked sadly

north stream
#

The older Pro Trinkets don't work with modern computers, so you may want to concentrate on the Feather or Nano.

balmy crow
#

tried both of those and dont work either

north stream
#

Do they show up on the USB device tree?

balmy crow
#

it does

leaden walrus
#

which specific feather is being used?

balmy crow
#

feather 32u4 basic proto atmega32u4 8mhz 3.3v

leaden walrus
#

it's unclear where/how a COM port is showing up, or not showing up

#

there is no COM port option for the Feather 32u4 showing up in the Arduino IDE when the Feather is plugged in?

balmy crow
#

avrdude: ser_open(): can't open device "\.\COM3": The system cannot find the file specified. is what shows up or the message cant find tinyusb

leaden walrus
#

COM3 is showing in the Arduino IDE? you say above only COM4/5 show up in the menu?

balmy crow
#

yes it doesnt show in the menu but its what the message says

leaden walrus
#

what board are you selecting in the Arduino IDE? under Tools->Boards

balmy crow
#

right now I have the pro trinket 5v plugged in so I have that one selected from the adafruit boards, with the nano I have arduino nano every

leaden walrus
#

for the pro trinket, the issue could be as mentioned above

#

what error message are you getting when trying to upload to the Feather 32u4?

balmy crow
#

SAM-BA operation failed

wrong board being selected

#

Adafruit Feather M0 (SAMD21)

#

the Feather M0 is different

balmy crow
#

okay yeah thx that one worked now but the others still dont hahah but thats maybe for an other day

leaden walrus
#

there may be no hope for the pro trinket

# 
The Pro Trinket bit-bang USB technique it uses doesn't work as well as it did in 2014, many modern computers won't work well. So while we still carry the Pro Trinket so that people can maintain some older projets, we no longer recommend it.
balmy crow
#

the nano also dosnt work

leaden walrus
#

may be running into that

balmy crow
#

might be yeah

#

thank you for your time!

Ah a clone

#

#

You need the CH340 drivers

leaden walrus
#

^^ that

gilded swift
leaden walrus
#

that's the chip on the backside

#

it's a USB-to-serial bridge

balmy crow
#

aah okay thank u!

leaden walrus
#

the pro trinket tries to do the same thing directly - via bit banging

#

which isn't as robust as the dedicated usb-to-serial converter chip

balmy crow
#

aah okay! this is very hulpfull I'll go check it out thank you all ❤️

Hi y'all! I'm looking to change some colors in an arcada sketch for the Clue. It's currently using; ARCADA_BLACK, ARCADA_BLUE, pink, greanyellow, cyan, white, and darkgrey.

But if I put in something like ARCADA_ROYALBLUE, it gives me an error saying that ROYALBLUE is not defined... However, I can't find where any of the other colors are defined in the sketch. Is there a list of official colors arcada uses or would I define ROYALBLUE as something like ROYALBLUE=65, 105, 225?

Thanks!

north stream
elfin thorn
#

Awesome sauce! Thanks @north stream !

north stream
#

It's probably easier to define your own ROYALBLUE, but you'd have to convert the values to the 16-bit 5:6:5 format. So 65 >> 3 is 8, 105 >> 2 is 26, and 225 >> 3 is 28. So I think ROYALBLUE would end up being 0x435C

elfin thorn
#

I'll give that a shot,

#

'cause I can't find the file for the arcada def.

#

So, my definition should look something like this?

#define ROYALBLUE 0x435C

north stream
#

Looks right to me. You could name it ARCADA_ROYALBLUE if you wanted, but I'd just have it like that.

Hi guys, I was directed here, hopefully not cutting anyone else for their chain. Has anyone worked with the mini gif player tutorial here: https://learn.adafruit.com/mini-gif-players/.My 147 is only showing black screen but it’s on. The serial port shows the below in repeat. It is stuck at frame 1.

I looked at some history and found someone with similar problem, but with no conclusive solutions. I tried the file cater sent out earlier, but didn't do much.

#

I checked the feather board with the blink code. it is working. I double/tripple checked the wiring, and can't seem to identify the problem

livid osprey
teal bluff
#

The feather is pluged into my computer

#

but there's also a lipo batter according to the tutorial, I tried with and without the batter

#

none of them worked

teal bluff
#

Wait, are those the safe mode stuff? What should I do when this is the case?

cedar mountain
# teal bluff What would cause a browout reset?

A brownout would tend to happen if the battery is too weak to maintain a working voltage under larger power loads, like running a chain of Neopixels or a motor. But it sounds like that's unlikely to be the case here, if it's running from USB power. In this case it's probably some sort of a software crash instead... Is the directory listing expected from your code?

#

I see this note in the Learn guide: "Invisible Mac files will crash the gif decoder. Make sure to remove all hidden files created by Mac OS". So I'm worried about things like the ".Trashes" file shown in that directory listing.

teal bluff
#

Hm

#

I tried doing rm from terminal

#

rm: ./.Trashes: Operation not permitted

#

is what happen when I try to remove that

#

but I will keep trying

#

thank you

#

now this is what my directory listing

the invisible files thing would be about the extended attributes files (._blinka-172.gif) since it would try to open it as a gif, but that doesn't seem to be the issue here according to the file name it gives

there is no usb hid library

there is only a library for circuitpython

How would people recommend using an Arduino with a bunch of inputs to be used as a controller for a game?

north stream
#

Have it send a representation of the inputs along to the machine hosting the game?

whole saffron
#

I kinda want it to have custom keyboard inputs if possible

upper robin
whole saffron
solemn cliff
#

and by "an arduino" do you have one you want to use (which one?) or can you be convinced to use one that has native usb and can act as a HID keyboard or controller ? (Like an arduino micro or a raspi pico)

whole saffron
#

Its an Uno

upper robin
solemn cliff
#

ah that doesn't have USB OTG, that's gonna be complicated

#

in fact considering the low price of the pico and other similar boards, I would consider a much better choice to buy one of those than deal with the complexity of trying to do it with a Uno

upper robin
solemn cliff
#

(and use QMK or look at one of the many CP macropad guides on the adafruit website)

upper robin
#

And the pico has a HID/keyboard library available

whole saffron
livid osprey
#

An original uno can be modified to add usb hid, but it’s a fairly complex process that involves reflashing the 32u4 that’s typically used as usb to serial. Better to use a pico or something.

#

Oh shoot that was from yesterday woops

tardy iron
#

i think it's either an ATmega8u2 or ATmega16u2, depending on revision, and yeah, you have to be comfortable with using SPI for programming it

#

i guess you could put a USB CDC bootloader on it, but it might be quite cramped for application code after that

whole saffron
#

Question about the Pico, any advantages the Pico has over the Pico W?

upper robin
#

If the command set were kept on the smallish side the DigiSpark would be worth a look too.

good afternoon, I have an ancoded mp3 file and used progmem, however I want the sound to play when I use a button and cant figure out how to code it. I have it in pin 11 when it works but cant find in the code where it says its directed to pin 11 does anyone know?

north stream
balmy crow
#

#include <PCM.h>

const unsigned char sample[] PROGMEM = { enter code for mp3 here };

void setup()
{
startPlayback(sample, sizeof(sample));
}

void loop()
{
}

#

I have this to play the sound and want it to activate with a button

#

thats what I'm trying and it only plays when in pin 11 I excluded the code for the sound bc its very long

north stream
#

Something like this? ```arduino

#define BUTTONPIN 11

void setup()
{
pinMode(BUTTONPIN, INPUT_PULLUP);
}

void loop()
{
if (!digitalRead(BUTTONPIN)) {
startPlayback(sample, sizeof(sample));
}
}

balmy crow
#

im gonna try a few things but it allready helped, I just started playing a zooming noise but its something haha

balmy crow
#

I might have something wired wrong? Because I tried a few things but the speaker just makes a weird sound and the button does nothing 😅🙏

rn_image_picker_lib_temp_72d9f63e-059b-4cc9-b1ba-70e5e43bec82.jpg
tardy iron
#

an Arduino Uno is probably going to have trouble driving a magnetic speaker directly (and flyback voltage may damage the chip’s GPIO circuitry)

#

the button looks like it’s wired to connect a 4.7k resistor between 5V and ground?

balmy crow
#

its connected to a resistor and that one to ground and the other pin of the button is connected to 5v but wasnt sure how to connect the grnd pin of the speaker, the way it is now it just makes sound but could have done it wrong

heavy star
#

Connecting the button to ground and 5V is just gonna short your power

#

The speaker might be making a sound because of the sudden voltage change when you press the button?

balmy crow
#

it makes the sound regardless of pressing the button, even if I take the button out it makes the sound haha

tardy iron
#

that seems consistent with the code you posted previously. it doesn’t read the pin. also, no GPIO pin is wired to the button

heavy star
#

Ah. Well, the button won’t do anything like that

#

The button should be connected to a GPIO and either ground or 5V, but not both, and your code needs to read if the GPIO is pulled high by connecting to 5V or low by connecting to ground

tardy iron
#

for a simple on/off input, the resistor isn’t strictly necessary, but can help prevent damage to the chip if you have the wiring or code set up wrong

balmy crow
#

aah okay thank you, I looked at a few vids and they did it this way. im very new to it haha

heavy star
#

Some videos make it hard to tell what they’re actually doing, lol

#

And some do things that are unnecessary because they don’t know any better

tardy iron
#

still good to use one in case you accidentally set a GPIO to output or something. though i’d personally use something smaller like 1k

Hi, I need to connect to a feather ESP32s3 (the one with the TFT) using JTAG and OpenOCD, but neither the vanilla 0.12 nor the ESP32 fork want to connect to it. I noticed, that the USB IDs are different and tried the ones from my board, but no luck. Are there any resources that explain how to connect to the USB Serial JTAG? Anything I'm missing here?

north stream
#

If it's USB-serial, then it should appear as a serial port. If it doesn't appear as a serial port, you may need a different driver.

wheat condor
# north stream If it's USB-serial, then it should appear as a serial port. If it doesn't appea...

That's actually didn't help at all. If someone is interested, the reason seems to be, that the ESP32S3 is in a different mode due to the stock firmware, opening Arduino, choosing Hardware CDC and JTAG as USB Mode, setting the other options to CDC and JTAG-related settings and flashing a sketch will put that right. Now I can connect to it via OpenOCD, rather simple fix, had to install the Arduino IDE (1.8) though. Now both vanilla as well as the ESP32 fork detect the board

wheat condor
#

Can someone give me a reasonable power draw, the Feather S3 TFT can handle, my setup seems to keep resetting in certain situations I've yet to suss out, but it looks like the 3v3 rail collapses

wraith current
#

@wheat condorunder what circumstances does it collapse ? At random or with a full brightness event or what ?

wheat condor
#

Well, I run a DRV2605, a VS1053, seesaw and an OrangeCrab off it, normally things are fine, but if I try to play sound on the VS1053, chances are high and if I have the DRV2605 play a longer rumble it tends to at minimum reset the seesaw

#

I'm running a very small ERM off the DRV2605

#

bit of a bigger setup, hence my question

north stream
#

It might make sense to run some of those off the VIN supply instead of loading down the 3.3V regulator powering the logic (and possibly putting spikes on it).

wheat condor
#

I'm using Stemma cabling for the DRV, the seesaw and VS1053 are run off the Feather rails, so I don't have any control over those and well, the OrangeCrab I could, it's a bit inconvenient though, since I then can't connect the 3v rail

sage lichen
#

So I have a fairly large arduino project, and I am trying to figure out how to run it locally only with the libs that arduino has access to

#

So like without the std library

north stream
#

What, the Arduino core library?

tardy iron
#

do you mean you want to simulate an Arduino on your computer?

sage lichen
#

Pretty much I am able to make "sim" versions of the libraries we've made for interacting with sensors and encoders and stuff, but I'm just looking for a way for me to have a local test env for me to run everything

#

I dont need to interact with pins or read values from pins or anything

#

Since all that is abstracted away anyways and can be easily swapped out

#

Just looking for a way to be able to test my code to make sure i'm not going out of the arduino standard library

zinc mortar
#

If you're just checking your calls, then compiling & linking should do the trick, no?

wheat condor
sage lichen
#

Pretty much its a flight controller for an airbake on a HPR and we have past sensor data that we are able to run through it, but we just want to make sure the algorithms are working correctly now and make further changes without having to recompile onto the board. Also can allow for actual TDD and stuff like that. One of the issues that prompted this was someone wrote a bunch of code that used stuff in the standard library but not available within arduino without doing some craziness

#

So just want to be able to test (not just compile, but execute) all that code without having to put it onto an actual microcontroller

#

Just speeds up the development process a ton

#

Really I'm just trying to figure out what solution they use in the industry for testing. Found something for doing exactly this, but for the STM32 in Rust

tardy iron
#

i think there is at least one AVR simulator. i don't know how easy it is to use, though

sage lichen
#

Yeah I had found something but it required running a jypiter notebook and stuff

#

I just wanna force the compiler to only use the arduino standard library

#

Emulate arduino standard library functionality such as "millis()"

#

And map "Serial.out.println()" and stuff like that to use stdout

zinc mortar
#

So you want to basically mock that stuff like you would in a unit test?

sage lichen
#

If this doesn't exist I'll just make it myself ig

#

Yes

#

But an integration test

#

One step below HIL

zinc mortar
#

Sounds like you have a lot of work to do; there's a lot in that API 🙂

sage lichen
#

Yeah that was why I was hoping there was something already out there 😅

#

I would just implement the functions we're actually using but still thats effort that could actually go into getting it to work lol

wheat condor
sage lichen
#

Thats true

tardy iron
#

mocking the (AVR) Arduino API on a computer won't catch the kinds of bugs you'll run into that are due to the AVR being 8 bits and your computer being 32 or 64 bits

sage lichen
#

Ok I guess I should have started with asking the actual question instead of jumping towards my (unoptimal) solution 🤣

#

The actual problem we ran into was people used vectors in a bunch of code

#

For matricies and stuff

#

And I didn't want to rewrite that stuff to not use vectors if I didn't have to since its way way above my head (I haven't taken linear algebra or anything)

tardy iron
#

compiling without uploading would have caught stuff like that, right?

sage lichen
#

Yeah it would've they were really dumb for even doing that

#

But at the same time, theres no intellisense in the old arduino ide

#

And the new ide is complete trash

#

So everyone just uses vscode (or clion)

tardy iron
#

there is a VS Code plugin for Arduino. it's a bit buggy and maybe not very well maintained

sage lichen
#

Yeah

wheat condor
#

That's your next mistake then, Arduino and its IDE is meant for small projects, use a real IDE, no VS Code, no Sublime, use Qt Creator or Visual Studio, mod your boards to upload via JTAG instead of the weird Serial and use proper debuggers

sage lichen
#

Oh trust me I am

#

Step by step tho

#

I'm working on a stm32 based board running rust with a jtag connector that can be emulated locally and have full test coverage and everything

#

But for this specifically we just have to work with what we have

tardy iron
#

proper on-chip/in-circuit debugging is amazing once you get it to work. my experience is you have to fight a lot to get the debug tools to work in any particular setup

sage lichen
#

Yeah I can imagine

wheat condor
#

Just got my first ESP32, was a bit of a pain to get USB JTAG running, but not too bad

sage lichen
#

But yea I try to use CLion for my contributions to everything, I'm just trying to figure out how to get it set up to work correctly (ie: recognize imported libs, etc)

wheat condor
#

Anyways, using std::vector for matrix math is a bad decision on that coders part, there are better types, since the size is static, but you should be able to convert that to straight up arrays easily. You can even try to rename std::vector to std::array and see what breaks. I'm not sure if uClib++ is even necessary to be honest, I'd just use the STL to get started and see what needs optimization later

sage lichen
#

Thats true

#

Yeah I guess I should just put in the work instead of finding a workaround

#

No reason for dynamic memory allocation for fixed sized matricies

wheat condor
#

Best way to not have to deal with stuff like that btw.: Talk to the coder, build guidelines and add linting and tests, that prevent this in the first place

sage lichen
#

Yea the problem was they kind of flaked on us

#

All of this was supposed to be done by them and ready by our launch yesterday

#

It wasn't 😦

#

And they didn't let us know until like 2 days prior

#

But yeah I def wanted to add tests which was one of the reasons for my initial question haha

wheat condor
#

also a typical occurance with at least 1/3rd of professional devs

sage lichen
#

But yea it should be pretty simple to write a header library to create bindings for some for the arduino standard library stuff like millis and serial.out

sage lichen
wheat condor
#

Anyways, good luck

valid hazel
sage lichen
#

Was hoping for something I could run on my own machine so I could do tests and stuff but beggars cant be choosers haha

tardy iron
#

the one i've heard of is called avrsim or something like that. i don't know how easy it is to work with

sage lichen
#

Omg I'm very stupid

#

So remember that emulator I was talking about earlier

#

The one that works with rust

#

Well uh

#

It works with the machine code generated after compiling rust (duh)

#

Which means it works just fine with arduino stuff 💀

If anyone wants to know the name its called QEMU

Have you checked, if you can flash your router firmware? Might already be the additional device you need. Otherwise, the smaller and lower power you go, the more complicated. You may even be able to do it with an Atmega328 with ethernet powered via USB, but it's a "project". I'd look for the smallest device with an ethernet port and linux capabilities, a Raspberry Pi is a pretty safe and reasonably easy bet.

Hi all! I have bought a Trinket 3.3v. Currently I have downloaded Arduino IDE and installed the boards thru board manager but still have no connection to my trinket. I can see it in device manager but not thru Arduino. Any advice to get my trinket connected?

north stream
#

The old ATtiny based Trinkets don't work well with modern USB chipsets. You may need to set the programmer type to "USBtiny" or somesuch in Arduino, and sometimes an old USB hub can act as a data converter.

have a nice day .I performed an I2C scan on a different sensor mpu6050 using the same pins and it was successful. I don't think it's an issue with my mcu.

Ah, that does narrow it down. So it seems to be an issue with that particular peripheral.

hmm what do u mean?

As you discovered, the MPU6050 shows up on an I2C scan, so it and its wiring, along with the CPU and it's I2C port, are working. However, the BNO055 doesn't show up on an I2C scan with (presumably) the same connection, implying the problem lies with the BNO055 or its wiring.

It's not really an Arduino question, but we'll go with it. The table does not look correct to me. The first column looks like NOT (A OR B) to me and the second column looks like NOT (A XOR B)

Hi! I'm having trouble understanding the General Timers, particularly the GTCCR. I did try to read through the datasheet but that has not helped simplify things for me. There are 3 marked bits in it( 0, 1 & 7) however I don't quite understand what the other ones are doing.

I have a question about the ESP32-S3 TFT Feather. There's an LED that lights up when the device is charging. Is there a way to read the status of that light, or power source, from arduino code?

the only thing connected to the battery pin is the LC709203F battery monitor, I don't know what it says when it's charging or if it can be used to know that it is

#

Thanks.Yeah, if it's in the LC709203F library, it isn't clear where.

dry quiver
#

I ran into a similar question but with the Qt Py lipo charger bff, which uses the same charger as the TFT feather apparently. That chip (MCP73831) has a stat pin, which powers the LED before going to VBUS.

#

What the bff does that is different from the feather though is that there's a voltage divider from VBUS that is hooked up to an analog pin so you can reference the battery voltage from there.

#

You can probably emulate that by doing the same externally.

does anyone know what exactly the arduino IDE does to open a serial port, i'm trying to write C++ code to mimic the serial monitor behavior and i can send data just fine but reading it is weird, m code works to read if I've already opened u the port, so to say, with the serial monitor in the arduino IDE, but my code wont read anything, it can still write, from the arduino if i unplug it and run my code without first "initializing?" the serial port in the arduino IDE with the serial monitor

serial port stuff is often very OS-dependent. also, if you have multiple processes opening the same serial port for reading, it can be unpredictable which of them gets the output at any particular time

Quick question: I'm currently using some Arduino Nanos and the RadioHead library ReliableDatagram manager with Adafruit RFM69HCW modules. I'd like to replace that hardware with Arduino Megas and RFM96W LoRa modules and use RHMesh instead of ReliableDatagram. My expectation is that I'll include and use a different driver and manager from the library and otherwise everything will work just the same - right?

The Mega shouldn't have any memory issues in particular?

You could make the app take care of it but with a physical switch, you'd read it in a loop, keep track of the previous state, and toggle when the state has changed from "not pressed " to "pressed "

I'm looking for a working example of Arduino code that wakes a MagTag from ESP32 deep sleep with a press on any of the onboard buttons. Per https://learn.adafruit.com/adafruit-magtag/pinouts, there are no pullups for these pins and go LOW when pressed. I've used the ESP32 ExternalWakeUp example (it appears in almost every online tutorial with minor modifications) with odd results. Using esp_sleep_enable_ext0_wakeup, I can wake from sleep on GPIO14 properly, but not GPIO15 or GPIO12 . Reviewing the MagTag pinout diagram, it's not clear what difference between GPIO14 and GPIO12 would be to cause this. Using esp_sleep_enable_ext1_wakeup doesn't work at all, regardless of what pins I set in the bitmask. ext1 has the disadvantage of its second parameter being any pin in the bitmask HIGH or all pins in the bitmask LOW. I added an rtc_gpio_pulldown_en() for one pin and modified the bitmask to use only that pin, but that didn't work either. I'm stumped and hope someone in the community figured this out. I've also got a Adafruit Feather ESP32S2 with the 2.9" epd Featherwing attached (three buttons, D11,12,13) that has the same problem with ext1. I haven't tested ext0 with it, as I really need the solution to respond to any of the buttons, not one specific button.

Cool, that sounds correct. Is it using a breadboard or soldered connections? (Read: are the connections solid or maybe somewhat loose?)

Do you happen to have a multimeter to check some voltages? The SCL and SDA pins should idle high at 3.0-3.3V, and the "3vo" pin on the breadboard should also be at 3.0V if it's getting power on Vin.

Hmmm, this is getting to the "well, it should just work, then" stage, heh heh. The next step would probably be trying an I2C scanner sketch to see if anything is detected on the bus at all.

Great! The 0x60 is the standard address of the sensor, so it's being seen. I'm not sure what the 0x6A one is, but probably some other chip on the Nano board.

#

Hmmm, although I am seeing some references to the Nano detecting those addresses by itself, too. You might try disconnecting the MPL and scanning again... it's possible there may be an address conflict with something already built in to the Nano board.

languid quartz
cedar mountain
#

The 0x6A seems to be the IMU on the board.

languid quartz
cedar mountain
#

I can't find what the WiFi radio's address is, but it has an I2C connection in the schematic too, so I suspect it's the 0x60 address conflict. 😢

#

So, unfortunately you're probably going to need to wire up the pressure sensor to a second I2C bus instead.

#

I'm not quite sure how CircuitPython handles this sort of thing, though.

I'm using the adafruit lvgl glue library, and it conflicts with one of the adafruit touch IC libraries (FT6206), because both STMPE610 included by lvgl glue and the ft6206 include the TP_Point class. The other thing is the Lvgl glue Begin() overloads require the STMPE610 which maybe could be rethought rather than adding the FT6206 overload and others too. I've gone down the route of using the Begin overload without touch, then I'll manually add touch.
So firstly thanks to the maintainers for latest fixes over the last few months, they've meant I can get lvgl going on the esp32s3 on wokwi (online or vscode arduino+esp32+pico simulator).
https://wokwi.com/projects/359264266487565313
How am I best proceeding if I don't want to include STMP610 which is brought in by lvgl-glue, should I create my own header file of matching name and include that first (with a define guard and recreate the class but without the TP_Point structure/class)

# north stream Enumeration is the first step of connecting a USB device. If that succeeds, then...

Right, that sounds great. But the thing is I have no clue how any of this works... I know that when a device would like to a communicate to a host it brings either D+/D- high based on what speed it would like to communicate. Then the host sends some data packages to ask for descriptors and configuration and then communication effectively happens. I don't know how to check any of this. I know this in theory from some youtube videos but I've never actually done any of this. I've tried using C/C++ and the pico-sdk to make my keyboard, but there is something wrong with the descriptors, I spent so much time trying to understand what is wrong but I don't have the tools to figure out what's going on. So I thought that using arduino + adafruit_tinyUSB would be a simpler option and I just followed the example, but it's either missing something or I am. Here is the example I was effectively copying: https://github.com/adafruit/Adafruit_TinyUSB_Arduino/blob/master/examples/HID/hid_boot_keyboard/hid_boot_keyboard.ino
and other than the fact that I'm not using neo-pixel I don't think there is much of a difference in the setup

Hello, everyone, I have a question about displaying images on a Adafruit 2.9" E-Ink Display - Displaying 1-bit image

I am able to display a black & white image to the display using the display.drawBitmap() function. The successful image draw uses const unsigned char data stored in PROGMEM (see below):

const unsigned char epd_bitmap_small_logo [] PROGMEM = {0x00, 0x00, 0x06....ect};

However, I want to display image data sent over from a Python program that I wrote, that program converts an image into black & white pixels & stores the data in a byte array.

Then the byte array is sent over Serial to an Arduino MEGA 2560 in hex format so I can use it to write the image to the display. I have also verified the hex data that is being sent over is correct. But the no matter what I try the image is garbled.

Has anyone successfully displayed an image to one of these displays using data that came from Serial & is not stored in PROGMEM?

cedar mountain
glacial viper
#

I think that is were I am going wrong & it seems like you know more about this than I do, despite reading everything I can find. I am almost certain I have two bytes of "1" and "0". I am stripping off the 0x from the ASCII hexadecimal, then I have a function that uses strtok to grab each hex value & store it into an unsigned char array which is then used with the drawBitmap function. An image is displayed, but its garbage.

#

char *sSample = "00 00 00 00 00 00 00 00 00 00 00 06..ect";
unsigned char Words[MAX_WORD_COUNT];
int word_count;

void setup() {
display.begin(THINKINK_TRICOLOR);
display.clearBuffer();
word_count = split_message(sSample);
display.drawBitmap(0,30,Words,62,60, COLOR1);
display.display();
}

#

byte split_message(char* str) {
int word_count = 0; //number of words
char * item = strtok (str, " "); //getting first word (uses space as delimeter)

while (item != NULL) {
   if (word_count >= MAX_WORD_COUNT) {
   break;
}
Words[word_count] = item;
item = strtok (NULL, " "); //getting subsequence word
word_count++;

}
return word_count;
}

#

Based on your suggestion, I think I got it partially figured out.
I needed to change Words[word_count] = item to:
Words[word_count] = 16*(item -'0')+((item+1)-'0');

still having a really weird issue with some Cpp code I'm writing thats meant to mimic the arduino IDEs serial monitor/plotter. basically I've got arduino code that monitors some sensors on its analog inputs and sends the values over the COM port every cycle. my Cpp code can successfully detect and open the port, and send instructions to the arduino. and it can read the data from the arduino, in a very specific circumstance. my code right now can only read from the COM port if I first (best guess here) "initialize" the connection by opening the serial monitor inside the arduino IDE. if I unplug the arduino, plug it back in and run my code without opening the serial monitor in the IDE, I read absolutely nothing, i can still send to the arduino just fine, but no data can be read. my best guess is the arduino IDE does something whenever I open the serial monitor that tells the arduino to start sending characters into the COM port, but im not entirely sure what it's doing.

cedar mountain
rugged mirage
#

does the serial monitor use a different COM port than what I'm uploading to? using a pro micro, so I assume I only have the one COM port, I didn't wire up a secondary COM port.

#

my app can't read from the arduino WHILE the serial monitor is open. but it can if i open the serial monitor, close it, and then run my app

#

but not if i unplug, plug it back in, then run my app wihtout first opening the same COM port in the arduino IDE with the monitor

cedar mountain
#

Hmmm. Is there some sort of boot message printed by the Arduino, which your code is getting confused by but it works correctly if the serial monitor eats that initial data first?

rugged mirage
#

shouldn't be the case because I'm erasing everything in the buffer before I read

#

and i should at least be able to read the boot message

#

the only writing I'm doing in my code to the serial monitor is in one serial.println() call that writes the entire string containing all the sensor values

cedar mountain
#

The only other thing which comes to mind is maybe there's some sort of a delay, like the Arduino has to spend a little time between when the serial port is opened and when it's ready to receive a command, whereas your code is opening the port and sending something immediately.

rugged mirage
#

might be the case. i can replicate my success with another app called realterm

#

so maybe im making some kind of mistake while im opening the port

solemn cliff
#

does your code use flow control ? dts/cts ? I don't know if it's necessary, but I know that C# serial for example doesn't do it by default and it can cause issues in some cases

#

does ther arduino serial monitor use flow control?

cedar mountain
#

Gotcha, yeah, I'm kind of grasping at possible straws at this point, short of just blaming Windows for weird COM port management. It's a puzzling problem.

rugged mirage
#

plus it can recieve just fine. i just cant read anything from it

#

should i try a different computer

#

hmmm

cedar mountain
#

How are you determining that the Arduino is receiving?

rugged mirage
#

im able to send instructions over the COM port to redefine some variables. i have LEDs that light up when a specific analog threshold is met. I can redefine what the threshold is by sending over a string with the values

cedar mountain
#

That's super-weird, then, to have a working connection but only in one direction.

rugged mirage
#

im also able to save the new values to the eeprom with a string command, and i can test that thats working by unplugging and plugging back in

#

the only possible explanation i can think of is that the arduino is waiting for some kind of signal before it starts talking over the com port

cedar mountain
#

Any chance it's something like CR versus CR-LF line termination in your command format, where the terminal is doing it one way but your app is doing it another?

rugged mirage
#

using println so the strings should be terminated with \r\n

#

i dont see how opening the monitor would change that

#

and thats what i see when i use realterm

zinc mortar
#

This sounds like you’re not setting COM port settings correctly- they’ll stick to the port after each application changes settings

rugged mirage
#

but id be able to send data with incorrect settings?

zinc mortar
#

If you omit one, then yeah

#

For example, if the port defaults to hardware flow control and you’re not explicitly setting it to software flow control, but the Arduino serial monitor does set it, then opening the Arduino one first would let yours work

rugged mirage
#

i got baudrate 9600, bytesize 8 bits, no parity, one stop bit, no flow control. that matches what i open the port up with realterm with.

#

hmmm

#

i can also change all the realterm settings and still see the data coming through

#

thats crazy

#

why would i be able to read whats coming from the arduino if im telling realterm that theres only 7 databits and 2 stop bits?

zinc mortar
#

Depends on the data, that’s still 9 bits

rugged mirage
#

okay so maybe realterm overrites the port settings? and the port settings arent on the arduino? but in windows? so maybe my app isnt writing the port settings correctly?

zinc mortar
#

Yeah, that’s what it sounds like

#

It’s always really finicky/annoying dealing with UARTs in Windows/Linux/MacOS

#

Sometimes you can check the current settings of a port using Device Manager too, BTW

#

I don’t know if you can inspect the settings (without changing them) using Realterm

rugged mirage
#

okay so I've directly mentioned all the terms in my constructor in my cpp code, i was letting them stay as default before, as they were still correct. that didn't seem to help

#

i can monitor the port settings in device manager

#

and opening the serial monitor in the IDE does not change them

#

but it still "fixes" my code

zinc mortar
#

Have you tried testing this with either a hardware loopback connection (like a USB UART with Tx and Rx connected) or a simple sketch that just loops back the data you read on the Arduino?

rugged mirage
#

not exactly sure what you mean by loopback.

you're saying i should write a sketch that reads data from the serial port and just prints it back out

zinc mortar
#

Exactly!

rugged mirage
#

still doesnt seem to work hmmm

#

but it still works on the monitor

#

wow

#

i can use my app to send some text to the loopback

#

try to read in my app, get nothing, open the monitor in the IDE and see the message i sent from the app being looped back

#

theres gotta be something im missing, some kind of command thats normal to send to serial devices but not necessary

zinc mortar
#

Wait, you see the text you sent in the serial monitor? If you were actually reading it, then you shouldn't see it in the serial monitor

#

It sounds like the text is still in the UART buffer, so perhaps your read() call isn't working like it should

rugged mirage
#

oh hold on

zinc mortar
rugged mirage
#

so when im calling read in my app im getting nothing.

#

but when i open the serial monitor i see it

#

so when im calling read in my app for some reason the data isnt coming out of the buffer

zinc mortar
#

Are you using a blocking read call?

rugged mirage
#

not sure

zinc mortar
#

Did you specifically set it to "nonblocking" mode anywhere?

rugged mirage
#

no

zinc mortar
#

So then when you call read(), your application should literally hang there until there's data available

#

If that read() call is returning and there's no data, that usually indicates an error. I think you then need to get the last error and then figure out what the error code means

rugged mirage
#

okay i think i can do that

zinc mortar
#

I think it's like GetLastError() or something in the Win32 API (it's been a few years since I've done C++ in Windows)

rugged mirage
#

last error is 0? x.x

#

I gotta call it a night. thank you for your help!

zinc mortar
#

Good luck!

I have these two snippets of code (from the USBHost library for the Arduino Due, plus the "CUSTOM PRINT"s)```cpp
TRACE_USBHOST(printf("CUSTOM PRINT (section 10) - Pre poll loop\r\n");)
// Poll connected devices (if required)
for (uint32_t i = 0; i < USB_NUMDEVICES; ++i)
if (devConfig[i])
{
TRACE_USBHOST(printf("CUSTOM PRINT (section 10) - Pre poll call\r\n");)
rcode = devConfig[i]->Poll();
TRACE_USBHOST(printf("CUSTOM PRINT (section 10) - Post poll call\r\n");)
}``````cpp
template <const uint8_t BOOT_SUBCLASS, const uint8_t BOOT_PROTOCOL>
uint32_t HIDBoot<BOOT_SUBCLASS, BOOT_PROTOCOL>::Poll()
{
TRACE_USBHOST(printf("CUSTOM PRINT (section 8) - Polling\r\n");)
uint32_t rcode = 0;

if (!bPollEnable)
    return 0;

if (qNextPollTime <= millis())
{
    qNextPollTime = millis() + 10;

    const uint32_t const_buff_len = 16;
    uint8_t buf[const_buff_len];
    uint32_t read = epInfo[epInterruptInIndex].maxPktSize;

    rcode = pUsb->inTransfer(bAddress, epInfo[epInterruptInIndex].deviceEpNum, &read, buf);

    if (rcode)
    {
        return rcode;
    }

    TRACE_USBHOST(printf("CUSTOM PRINT (section 8) - Post time check w/ pRptParser = %d\r\n", pRptParser);)

    if (pRptParser)
    {
        TRACE_USBHOST(printf("CUSTOM PRINT (section 8) - pRptParser check passed\r\n");)
        pRptParser->Parse((HID*)this, 0, (uint32_t)read, buf);
        TRACE_USBHOST(printf("CUSTOM PRINT (section 8) - Post parse\r\n");)
    }
}

TRACE_USBHOST(printf("CUSTOM PRINT (section 8) - Polling end w/ rcode = %lu\r\n", rcode);)

return rcode;

}The program gives the following output

HIDBoot::Init : HID device configured successfully
USBHost::Configuring : found device class!

The fact that it printed "Polling end" didn't print "Post poll call" seems to imply that it failed on the return... Any idea what's happening?
cedar mountain
#

One possibility is that you might be seeing some time-delay distortions... like the next print statement is still in a buffer somewhere, but the code crashes immediately after that in such a way that it prevents the trace message from being sent. You might consider including a delay after the missing "post poll call" statement to let it be fully output before proceeding. (No idea if this is the real problem, but I've sometimes run into this sort of thing with printf debugging in general.)

blazing crane
#

👍

#

I'll give it a shot

obsidian geyser
blazing crane
#

Nor did returning a hardcoded 0 from Poll instead of the rcode

cedar mountain
#

Bummer. It's so frustrating when the debugging techniques themselves are behaving weirdly...

blazing crane
#

Any ideas? I don't think a function return can cause a hang, and I don't believe there's any asynchronous/threading/anything else happening at that moment in time that would cause it to break at that point...

#

I will also note that it works perfectly fine when connected to a mouse, it's only the DualShock4 that breaks this. I had a USB cable I'd hacked together that I could use to view the USB packets between the Due and DS4, but the cable broke and I'm still waiting on the supplies to make one "properly"

#

Gonna try printing the contents of some buffers to see if there's an issue there

cedar mountain
#

The only thing I can think of is that somehow the stack frame has been corrupted so that the return doesn't have a valid pointer to use.

blazing crane
#

Any way to check that?

zinc mortar
#

Usually you'd use a hardware debugger for that- the Due has the standard 10-pin Cortex debug header on it

blazing crane
#

Yeah, there's the little 10 pin JTAG port and a bigger (2.54mm) 4 pin "debug"

#

I'll see if there's a hardware debugger around, though I doubt it

#

Unless I can use another Arduino/Pi or my DSLogic Plus (logic analyzer), then probably not

zinc mortar
#

There could be a port of Blackmagic Probe for Due? I haven't checked

blazing crane
#

Ok, so the code has a buffer of length 16 for storing the incoming report data. The DS4's reports are 64 bytes long. I'm trying increasing the buffer 64 to see if that fixes anything ¯_(ツ)_/¯

#

that might have done it!

zinc mortar
#

Woo!

blazing crane
#

Think it overflowed (overflew?) and messed up the stack?

zinc mortar
#

Certainly plausible

blazing crane
#

It's still just a stream of unparsed bytes, but it finally works!

The ESP32 has built-in WiFi, so you can get a network connection for that sort of thing. Not sure of the Ethernet options off the top of my head, but it's likely possible with some boards.

I don't know where to ask this but I have an ItsyBitsy nrf52840 sketch written in the Arduino IDE that works fine on a Mac but Serial.begin() never returns true when the device is plugged into a Windows 10 machine. Strangely a COM port appears as soon as the device is plugged in and if you double click the reset Windows opens a folder to the disk drive on the ItsyBitsy. But if you do nothing it spins forever in while(!Serial.begin()); I have tried this on two different Windows machines.

Thanks Cater. I do include <Adafruit_TinyUSB.h> because it is needed for the BLE stuff however I am not having a problem with loading becuase I loaded the Sketch when the device was connected to the Mac. The code only makes it a couple of lines Serial.begin(57600); // Initialize serial port I/O. while (!Serial) // Wait for serial port to connect. Required for native USB! { digitalWrite(PIN_LED1,!digitalRead(PIN_LED1)); // Blink while waiting delay(20); }

leaden walrus
#

this code snippet:

Serial.begin(57600);
while (!Serial);

will loop until something opens a connection to the serial port - like the Arduino Serial Monitor. just plugging in and seeing a COM port show up is not enough.

Any tips for trying to learn C++ for Arduino?

pine bramble
dry quiver
#

Try simple projects with it. I ended up dipping into Arduino's flavor of C++ because I was forced into it with a project that I couldn't do as fast with Python and I needed the speed. So I tried rebuilding the same concept in C++ and pretty much built off from there.

gilded swift
#

Blinking some LEDs is a great way to start and build confidence 🙂

dry quiver
#

Yup. Start by figuring out how digital/analog inputs and outputs work since you'll be interfacing with something one way or the other using those.

Add heat-vision to your project with an Adafruit AMG8833 Grid-EYE Breakout! This sensor from Panasonic is an 8x8 array of IR thermal sensors. When connected to your microcontroller (or raspberry Pi) it will return an array of 64 individual infrared temperature readings over I2C. It's like those fancy thermal cameras, but compact and simple enough for easy integration.

#

so 8x8?

Hi all, I'm trying to read the battery level from a LiPo connected to an Adafruit Feather nRF52 Bluefruit in software. I've found several references to the BLEBas battery helper, but all example uses show it simply being set to 100% at the top of a program, then not being touched again.

Can this helper be used to read the battery level of a LiPo as a percentage relative to the total capacity of the battery, or is this only meant to read the battery discharge over time relative to its capacity at the time it was set to 100% in software?

Hello everyone!
I posted a question on help-with-projects and it was suggested to repost it here.

#

First of all I'm new to this.
So in the context of BLE communication and working with nrf52s... I've been looking at the Adafruit examples and when a peripheral device advertises itself to the world, they always include the device name to ScanResponse. From my understanding and from what I read, in a scan event there are 31 data bytes sent first, and eventually with the right configurations a second 31 data bytes can be sent by the peripheral to the central device. The ScanResponse goes in the second one. This is what I could understand.
In order to get the second 31 data bytes the scanner (in central) should have useActiveScan set to true, and then in setRxCallback a scan_callback where we handle the event.
The scan_callback has a parameter ble_gap_evt_adv_report_t* report from where we can actually can get some information about the peripheral device. Unfortunatelly so far I couldn't get successfully the device name if the device name is add to the ScanResponse. I can successfully get it if and only if I add it to the first 31 data bytes:

  uint8_t buffer[10];
  memset(buffer, 0, sizeof(buffer));

  uint8_t res = Bluefruit.Scanner.parseReportByType(report, BLE_GAP_AD_TYPE_COMPLETE_LOCAL_NAME, buffer, sizeof(buffer) - 1);
  Serial.printf("Got successfully device name? %u \n", res);

I spent some time exploring... I also print in the scan_callback the following:
Serial.printf("scan_response is: %u\n", report->type.scan_response);

And the value is always zero, from my understanding I was guessing this value could change to "1" if it was a scan response.

So what I am trying to achieve is getting the device name from a ScanResponse without connecting with the device, at scan (GAP) level, not at connect (GATT) level.
Note: I used the smartphone apps Bluefruit LE Connect and nRF Connect (from Nordic) and in both I can with a scan get the device name, so the device name goes for sure in the advertisement.

Anyone can help me?
Thank you in advance!

pine bramble
# pine bramble Hello everyone! I posted a question on help-with-projects and it was suggested ...

Also I want to include that in meanwhile I've been exploring and trying to understand what's going on.
I notice something strange, if I do only Bluefruit.setName the nRF Connect (Nordic app) can't see the device name, but the Bluefruit LE Connect can! Notice no name added to the advertising or scanresponse! And the raw data is: "02 01 06 02 0A 04 03 03 0F 18 11 07 4C 40 60 FC 9D D5 CA 92 FB 48 AB 11 89 65 FE 2F", is already full, it contains the BLE_GAP_AD_TYPE_FLAGS (01), BLE_GAP_AD_TYPE_TX_POWER_LEVEL (0A), BLE_GAP_AD_TYPE_16BIT_SERVICE_UUID_COMPLETE (03) and BLE_GAP_AD_TYPE_128BIT_SERVICE_UUID_COMPLETE (07). Filling in total 28 bytes of the 31 available. It is needed 5 bytes to include the string "T01" (what I need to include), so no room for it.
But for me this is a mystery. How Bluefruit LE Connect can see it?
I don't have a sniffer, so this is what I can tell from observation.

I also saw a related post in the forum (with no answers). The person was using this example: https://github.com/adafruit/Adafruit_nRF52_Arduino/blob/master/libraries/Bluefruit52Lib/examples/Central/central_scan_advanced/central_scan_advanced.ino
I tried the same, and got nothing, apparently nRF52 is unable to read the ScanResponse from the one that is advertising.
Note: I still look at the Bluefruit LE Connect and nRF Connect and both can read the device name from scan response like it was nothing.

okay I've changed languages and now im not using any third party weird libraries but im still having trouble opening my serial port. looks like its pretty much confirmed that I don't know what the Port settings are supposed to be, but things like the arduino IDE serial monitor, PuTTy, RealTerm, and the MVS serial monitor can all open the portand read the data coming in. so they have to be able to detect the correct settings. does anyone know of some kind of program I can run that will output the correct Serial Port settings?

#

@random zealot you'll need to link to the pieces or upload them (use the "+" to the left to upload a file)

random zealot
safe shell
#

generally, Arduino code has one-time set-up code, then a loop that runs forever. each of your pieces is probably already structured like this. you'll need to put the set-up pieces sequentially, then put the loop pieces sequentially within your main loop

#

there should only be one setup() and one loop() when you're done

#

(theoretically, you could have three different setup functions, each named differently

#

e.g., setup_rtc(), setup_neppixel(), etc.

#

but you have to call them somewhere before the main loop

and did you do make BOARD=... flash-sd and then make BOARD=... flash. The first will get the SoftDevice onto the flash, the second will flash the bootloader. Then double-click reset to get the BOOT drive.

perhaps worth trying the process with a PCA10056 or PCA10059 dev board to vet the recipe

Does anyone have a deep knowledge of the Adafruit DotStar Library? I'm having big issues between Serial.out(); and Adafruit_DotStar Strip1(dotStarCount, dotStarDataPin, dotStarClockPin, DOTSTAR_BGR); where either I can serial out information or communicate with the DotStar but not both. Super confusing. Strand test works fine. Happy to pay for help. Thanks! https://github.com/matteblackrobotics/CalendarRingGit/tree/main/Wyzant/Test2

Good Morning, I have an arduino Zero with a pin 7 wired as output. Instead of using variables for known state of output I used digitalRead(7
) == HIGH This is always return false. I am looking at pin 7 and I am toggling it High and Low and it is changing state. If a pin is defined as output, how can I know the state of the pin?

Hi. I'm trying to discover the remote control button codes in arduino IDE but i don't get any message in the Serial Monitor. The IR Receiver blinks when i press the remote control button but i don't receive the code of the button in the Serial Monitor. What could it be? Thanks!

Could be a serial monitor problem, could be an IR receiver/decode problem, could be a data format problem

That's what I'd do: break the problem into pieces and test each piece individually. Divide and conquer.

Wanted to show what I came up with thru trial/error (gloat gloat). May not be new to youse guys... On a TFT display ST7735 (Adafruit_GFX lib), instead of having to clear/redraw the whole display, I have one line showing data frequently updated. So, use fillRect to clear a small rectangle of the previous value - set color to whatever backgound is (black for me), then show the new text. Very fast and works well for my use... Code:
tft.fillRect(40, 84, 72, 22, ST77XX_BLACK);
tft.setCursor(42, 98);
tft.print(mins); tft.print("m:"); tft.print(secs); tft.print("s");
Took some tweaking to get the coordinates right...

@dim tree generally you give some context, post your code (use the "+" to the left, or for small snippets you can format it in a message - see the #welcome channel for how to format), and the specific question or issue you're having

okay all look that up

# faint gulch does anyone know?

Initialize a value to be false, and if the height is exceeded, set to true. Then, have your buzzer start only if the value is true.

safe shell
#

@faint gulch you'll need some if statement with the thresshold value, triggering the output. The BMP is good at relative altitude, but absolute is challenging, you'd need to frequently adjust MSL

Hi. I'm having troubles getting EEPROM to work on my ESP8266. I can save stuff to the EEPROM and also read it, but when i save a other value in a other spot (address) the first value sometimes gets 0 or something else.
In my code im setting 3 different presets for RGB Values, so Preset 1 is (Red on address 1, Green on 2, Blue on 3) and the same for the other colors (with other addresses). But when reading them sometimes it works, and sometimes i get a random color or none at all.

Trying my first time to right out a format to explain my question and problem with this Arudino and Python code that I am trying to figure out.
Problem
It is trying to customize a eye with python code using a code that is from Adafruit website called “Electronic Animated Eyes for ARM Microcontrollers” by Phillip Burgess
There is info on this how to customize but me being brand new to python I can’t figure out the missing steps.
They say you need Python and Python Imaging Library installed and I have them both Python 3.10.10
The python script is located in the convert folders from there Github repository -tablegen.py- which I have in the folder on my computer C:\Users\NAME\Uncanny_Eyes-master\convert and I have python install folder in this same folder because I was reading that you might need to do this.
So they say to recreate the deafultEye.h file which Is in the Uncanny_Eyes-master folder you go to the “CONVERT” directory and enter this command (as a single line) python tablegen.py defaultEye/sclera.png defaultEye/iris.png defaultEye/lid-upper-symmetrical.png defaultEye/lid-lower-symmetrical.png defaultEye/lid-upper.png defaultEye/lid-lower.png 80 > defaultEye.h
Now after that I open up my cmd prompt on my windows 10 computer and use this code and get this error
C:\Users\NAME>python tablegen.py defaultEye/sclera.png defaultEye/iris.png defaultEye/lid-upper-symmetrical.png defaultEye/lid-lower-symmetrical.png defaultEye/lid-upper.png defaultEye/lid-lower.png 80 > defaultEye.h
python: can't open file 'C:\Users\PHOENIX REBORN\tablegen.py': [Errno 2] No such file or directory

Now I am unsure how what that means I did read its because it can’t the file in the directory because its looking for it someplace else but I am not sure how to redirect that file to be found?
This adafruit site has just that one page talking about how to customizing but doesn’t show how to problem solve if u have errors so if I could get some guidance on this it be most appreciated.

ah they are in convert

so you want to:

@faint gulch do you have a meter (or even an LED) to check that the pin 6 level is as you expect?

tbh i don't really care what it does as long as i can hear a loud beeping, so tone() would be fine i think

using the buzzer so that i can hear where it is

@faint gulch do you have a link to the buzzer product? double-check wiring, maybe put your buzzer high-low test code in the setup to confirm on startup that's it's working like when you tested it

#

I don't know, since both commands use the same "python" (which is why I use python -m pip instead of calling pip.exe) that should not happen, maybe it's missing some configuration with python on windows, but that's beyond my knowledge

#

I'm also surprised with the path it took you to when you entered the example directory, maybe check that the zip is properly decompressed and not like a shortcut ?

dim tree
solemn cliff
#

ah that might be why it took you to system32

dim tree
#

so i think it works now

solemn cliff
#

🎉

dim tree
faint gulch
#

so i guess the buzzer works, but now it needs to be only triggered when the height value has been above a certain level. then stay on

safe shell
#

what is the value of height?

faint gulch
#

euh

#

idk tbh, but the value i need is the value it prints here:

safe shell
#

if you print it there, you'll know the value, and know that you're reaching that part of the code

#

ah, ok

faint gulch
#

this works. i see it print

#

however, the normal reading shows, for example, 0.88. "Height" shows 0.
When it reaches, for example, 2.32, "height" shows 2. Not a problem to me because i will be using a rough number like 100 anyway

#

but now i'm stuck on how to continue from here

# solemn cliff 🎉

hmm i got to work once but now getting that same error about the No Module named "PIL"

solemn cliff
#

make sure it is run in the same environment as before, check you are not in admin mode or... something ?

dim tree
solemn cliff
#

try the pip install again in that prompt maybe ? restart a new prompt ? It would be weird if the script itself broke the environment, but 🤷

#

@faint gulch you declared height as an int, so it will truncate

I don't know why the comparison to -3 wouldn't work

probaly some syntax thing like no semicolon or no closed-curly brace

#

so, i assume that i need to add that -3 script thingy over here: is there any thing i should look out for?

#

note: if beepheight is not big enough, the script under it still needs to be ran

#

(Yeah I changed height to beepheight so it’s more easy to remember what is does)

Oh wait I found something online which might make it work

faint gulch
#

Okay. It doesn't give an error anymore, but it doesn't work either

#

anyone know why?

zinc mortar
#

Does bmp.readAltitude() return an integer or a floating-point number?

faint gulch
#

it prints for example when bmp.readAltitude is 1.34, 1 for beepheight

#

but truncated to an int it will not be strictly greater than

faint gulch
#

i'm not a native enlish speaker and a bit of a noob

safe shell
#

how about: if (beepheight >= 0) just for test

faint gulch
#

okay

#

yeah doesn't work

putting a float (bmp.readAltitude) into an int will truncate it as you posted earlier (.88 becomes 0)

does it work without the if () in loop()?

#

I don't think you can call millis() inside an interrupt

#

And possibly Serial.println() is not allowed either

#

Also if you're modifying values like that in an interrupt, you should declare them as volatile

#

But if you're really looking to measure pulse widths like that, you'll probably need to set up a timer for it. The Arduino "irremote" library is a decent example of how to do it

cerulean urchin
#

I just used millis() so it wouldn't count to fast

cerulean urchin
zinc mortar
#

Also, "rst cause 2" is a watchdog reset, which usually means you spent too much CPU time and the WiFi stuff didn't get a chance to run

livid osprey
# cerulean urchin I just used millis() so it wouldn't count to fast

Most interrupt functions are designed to be as minimal as possible to prevent it from blocking regularly scheduled cpu tasks. Usually it’s just increment some global byte or switch a Boolean to true, then your loop function does the heavier processing outside the interrupt as it reads the values at its regular intervals.

Hi guys, probably a stupid question but I am rusty and this will be my first time using the WS2812 neopixel 5050 sticks.

neopixels in general are just one long chain

Hello everyone! I am using a Raspberry Pi Pico and a BNO055 and I am trying to get the 12C pins of the BNO055 to communicate with pins 21 and 22 of the pico (GP16 and GP17 respectively). When I do Wire.begin(21, 22); I get the following error :

   Wire.begin(21, 22);

What does this mean and how can I resolve it?

#

Hello. I'm using interrupts on my SAMD21 (48 MHz) to perform analog sampling at 30 kHz (actually 31.25 kHz, as I am using a prescaler of 256). The interrupt routine call intervals are very precise. Does anyone know how I can implement direct DMA data buffering to an SD card? I need to continuously read the analog pin by the processor and the time it takes to write the buffer to the SD card executed by the processor is significant and causes a loss of signal timing.

cedar mountain
#

You generally wouldn't be able to do a "direct" DMA to the SD Card, but the general pattern would probably be to have the sampling interrupt fill up a larger circular buffer, and when you've accumulated enough samples, you'd perform a SD write in a non-interrupt context. That could be processed either by DMA or by FIFO-filling interrupts depending on how your SPI driver handles things.

thorny cedar
cedar mountain
#

I'm not familiar with the SAMD21's DMA capabilities, but generally I'd expect there to be a way to set up a "memory to peripheral" transfer where the SPI would tell the DMA controller when it's ready for another byte.

I'm trying something like:

// Initialize SPI
    SPI.begin();
    SPI.setClockDivider(SPI_CLOCK_DIV8); // Set SPI clock to 1.5 MHz

    // Initialize DMA
    ADC_DMA.setTrigger(SERCOM4_DMAC_ID_TX); // Use SERCOM4 TX as DMA trigger
    ADC_DMA.setAction(DMA_TRIGGER_ACTON_BEAT);
    stat = ADC_DMA.allocate();
    ADC_DMA.printStatus(stat);

    // Configure DMA descriptor
    ADC_DMA.addDescriptor(T2, (void *)(&SPI.), BUFFER_SIZE / 4,
                          DMA_BEAT_SIZE_BYTE, true, false);

    // Set DMA transfer callback
    ADC_DMA.setCallback(dma_callback);
cedar mountain
#

I'd generally advise you not to try to go directly from the ADC to SPI with one DMA transfer, since the SD Card driver is going to want to do other SPI writes to manage the filesystem as well. You probably would want to buffer up samples in memory somewhere first.

Gotcha, I was confused about what you're doing from the use of the SPI TX as the DMA trigger.

@leaden walrus Can I load the Philhower core through a clone of the repository? I think I remember how to do it, but I've only ever done it for ESP, I think, and I am not sure that concept applies to everything or not.

leaden walrus
#

sounds like a manual BSP install? if so...should be nominally same process as ESP

pallid grail
#

OK, I'll try to find those instructions. I think I found where it goes, but I'm not certain what determines the directory structure that contains the clone

#

I figured it out. And it worked.

#

Thanks!

I have done this:

Wire.setSDA(21);
Wire.setSCL(22);

And I still get this following error:

Hey guys, I have an l298N h bridge and I have my Arduino d4 and d5 hooked up to IN1 and IN2 on the power input the hbridge im reading 12.5 volts but no matter what I do with the code the outs aren't measuring anything. When I meaasure d4 and d5 its going between 0 and 4.5 which makes sense. Any help would be very much appreciated. Thanks

int IN1 = 4;
int IN2 = 5;
// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(IN1, OUTPUT);
pinMode(IN2, OUTPUT);
pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
digitalWrite(IN1, HIGH);
digitalWrite(IN2, LOW);
delay(1000); // wait for a second
digitalWrite(IN1, HIGH);
digitalWrite(IN2, HIGH);
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(1000); // wait for a second
}

Note that the L298 has two power inputs, one for the logic (which should get 5V) and a separate one for the motors. Note that it also has current sense and enable pins which also need to be connected correctly.

Just starting to play with Tasmota. Before I pony up for an actual device like a bulb or switch, what's the likelihood that I can at least test basic functionality on an esp8266 feather? This means getting wifi working, at least establishing a connection to an MQTT broker, and maybe poking at the web UI, and seeing if I can flash using the OTA upgrade workflow.

Hello, has anyone had issues with connecting the datalogger shield to their arduino? The RTC works fine, but I cannot seem to connect the chipset 10 SD card.

I think that's the shield I used in my water heater logger, and it seemed to work well for me.

Bugger. @leaden walrus Are you idle-idle or not-looking-at-Discord-idle?

#

I'm in a hurry and having issues I don't know how to troubleshoot.

leaden walrus
#

@pallid grail whats up?

pallid grail
#

So I installed the Philhower core locally.

#

and tried to load the blink sketch

#

I'm getting this: ```In file included from /Users/kattni/AdafruitDev/Arduino-1x/hardware/earlephilhower/arduino-pico/cores/rp2040/Arduino.h:28,

#

And I got all that Invalid library found stuff on every sketch I had open after installing it, repeatedly.

#

So when I wasn't even trying to compile anything.

#

Wait, did I need to do a git submodule --init --update or something on the Philhower clone?

#

update --init oops.

leaden walrus
#

that's my guess. based on quick look at the repo

pallid grail
#

OK, trying that now.

leaden walrus
#

it has some submodules

pallid grail
#

.... It says it's not a git repository.

#

Wait I used the zip. Ugh. Ok, deleting and actually cloning

#

That worked.

#

Well, I mean it's running now.

#

Time will tell if it works.

pallid grail
#

reloading Arduino.

@leaden walrus Now I'm getting this.

leaden walrus
#

did you do the submodule thing? looks like probably also needs the pico-sdk

pallid grail
#

I did.

#

I can try it again. Says pico-sdk checked out though

#

In the list of things it did

#

Running it again did nothing.

leaden walrus
#

./pico-sdk/lib/lwip/src/include/lwip/init.h

#

is that showing up in your local copy?

pallid grail
#

There's nothing in the lwip directory. It's empty.

#

Trying something

#

Nope.

leaden walrus
#

what was your submodule command?

pallid grail
#

git submodule update --init

#

wait

#

do I need a recursive or something

leaden walrus
#

try --recursive

pallid grail
#

Uff. Trying that.

leaden walrus
#

git submodule update --init --recursive

pallid grail
#

That looks like it might fix this issue.

#

It is doing more, and I see lwip going by.

#

Uff this is like running that in CircuitPython, lol.

#

Not nearly as bad, I'm sure, but this is a lot happening.

#

If it works, I don't care.

leaden walrus
#

the submodules probably have submodules that use submodules that depend on submodules, etc.

pallid grail
#

Exactly what this looks like.

#

Yo dawg. I heard you like submodules.....

#

Done

#

Trying again.

I didn't even look there for it.

OK, redoing.

i think you've done most of that

maybe that last bit?

yah, try that

Ok, yeah. Got it.

Reloading Arduino.

#

Sigh. It's crashing.

#

Trying again.

#

@leaden walrus Ok, it's crashing when I click on the Tools menu now on a fresh load. The only sketch pulled up is the Blink sketch built into the IDE.

#

Trying to start it without the board plugged in

leaden walrus
#

the arduino ide is crashing?

pallid grail
#

Yes

#

Even without the board.

#

Open the app, let it load, Blink sketch is there, click Tools, rainbow wheel-crash.

#

leaden walrus
#

have you used that core before? installed thru the arduino ide?

pallid grail
#

Yes. It's there from the board manager as well. But that doesn't have this board, so here we are.

leaden walrus
#

did the get.py install things ok?

pallid grail
#

Looked like it. It ran and then went back to my command line.

leaden walrus
#

what's in the tools folder now?

pallid grail
leaden walrus
#

oops. sry. meant the system folder

#

/Users/kattni/AdafruitDev/Arduino-1x/hardware/earlephilhower/arduino-pico/system

pallid grail
leaden walrus
#

hmm. ok. it installed stuff.

#

sudo arduino?

pallid grail
#

llol

#

I was thinking moving the whole directory, loading Arduino, picking a different board, then moving it back to see if it is stuck in some weird state from not having everything the first time I opened Arduino.

leaden walrus
#

maybe. let me run through the manual install also.

pallid grail
#

Thank you

#

I did delete all I had and go through their exact steps

#

So, we'll be in the same place if you do too

#

Ok defaulted to Flora. One more time.

#

No crashing this time.

#

Trying Blink again

#

Hooray!!

#

No errors at all!

#

@leaden walrus That did it

#

So I guess, pro tip: Don't open the IDE until you follow all the instructions. 😄

leaden walrus
#

cool. working now?

pallid grail
#

Yes! Thank you so much!

leaden walrus
#

yay! np

Whew! Now I can actually get the last pages in this guide done to try to get it in before show deadline.

Has anyone with some SAMD21 experience had any success writing to SD without CPU usage?

I'd tend to recommend you get it working without DMA first, just to familiarize yourself with how to write files at all, etc. And then go back to optimize things if you have to.

Huzzah output charging current?

Apologies in advance if I've posted this to the wrong list. Does anyone know the output charging current for the Huzzah ESP8226. It seems to be taking forever to charge my 4400mA battery.
The battery wasn't dead, and powers the Huzzah fine. These batteries are new and haven't been used, so I thought its best to fully charge them so they don't discharge while being stored.
I was just performing a full charge on the battery.
It been already been over 12 hrs charging and the charge indicator hasn't gone out.
I know the charging is working because I also charged 2 other 2000mA batteries with it, although it took sevearl hours each to fully charge them.

20230405_133407.jpg 20230405_133547.jpg
leaden walrus
#

oooo..yah...i think the default charge rate is tiny

# 
We don't recommend setting the charge rate below 100mA or above 500mA but as long as its well documented why you chose it, its fine.
#

looks like it's about 200ma

#

which maths out to be about a ~22 hour charge time 😦

#

for the 4400mAh battery

#

the reasoning for such a small default charge rate is to support the small lipos that are also in the shop - like the 150mAh one

Hey can someone help me out? 😅 Im trying to use DMA to read multiple pins and store it in a struct so when all pins have been read the loop is allowed to print this data. Reading 1 pin works just fine but anything greater then like 2 doesnt work properly. The data gets associated to the wrong pin.


// Define the pins to read from
const uint8_t ANALOG_PINS[] = {A0, A1, A2, A3, A6, A7};
const uint8_t NUM_ANALOG_PINS = 6;

Adafruit_ZeroDMA ADC_DMA;
DmacDescriptor *dmac_descriptor_1;
DmacDescriptor *dmac_descriptor_2;

uint16_t adc_buffer[SAMPLE_BLOCK_LENGTH * 2];
uint16_t adc_sample_block[SAMPLE_BLOCK_LENGTH];
volatile bool filling_first_half = true;
volatile uint16_t *active_adc_buffer;
volatile bool adc_buffer_filled = false;


//volatile int pins_read = 0;
std::atomic<int> pins_read(0);

struct ADC_Data {
  uint8_t pin;
  uint16_t value;
};

ADC_Data adc_data[NUM_ANALOG_PINS];

void dma_callback(Adafruit_ZeroDMA *dma) {
  (void) dma;
  // Double buffering prevents when the DMA transfer is ongoing and the buffer is being filled with new samples, the microcontroller may not have enough time to process the data before the next round of ADC sampling begins.
  if (filling_first_half) {
    // DMA is filling the first half of the buffer, use data from the second half
    active_adc_buffer = &adc_buffer[SAMPLE_BLOCK_LENGTH];
    filling_first_half = false;
  } else {
    // DMA is filling the second half of the buffer, use data from the first half
    active_adc_buffer = &adc_buffer[0];
    filling_first_half = true;
  }
  adc_buffer_filled = true;
  
  uint8_t pin = ANALOG_PINS[pins_read];
  uint16_t value = active_adc_buffer[0]; // Store only one value for simplicity

  adc_data[pins_read].pin = pin;
  adc_data[pins_read].value = value;

  pins_read = pins_read+1; 
  if (pins_read >= NUM_ANALOG_PINS) {
    pins_read = 0;
  }

does anyone know how to use the SoftWire library with the Adafruit_BME680 library?

north stream
#

It looks like the BME680 constructor accepts an argument of an I2C object, so presumably you'd just hand it the SoftWire object.

awesome, would that be in the .begin part or before the void setup part

awesome thanks!

#

when i tried that i got an error that it couldn’t convert SoftWire to TwoWire

north stream
#

Unfortunately, I'm unfamiliar with the SoftWire library, I was hoping it exposed a TwoWire interface. Since it doesn't, you would either need to find a different I2C library that does, or get into some software modification.

#

You can't use the existing I2C port for some reason?

lament dune
#

yeah, the i2c bus overlaps some analog pins and i need those for sensors
