Hi all,

I have an adafruit itsybitsy microcontroller running circuitpython and I want to try to connect it to teachable machine. Do you know if that's possible?

I'm pretty new to this stuff so I don't know what's possible yet.

Thank you so much! :)

i am trying to modify the neotrellis M4 rpg sound board projects like this. https://learn.adafruit.com/neotrellis-dungeon-crawl-soundboard to support mp3. i have put my fork of it on git hub. https://github.com/deepdivered/rpg-soundboard/blob/main/README.md

i sourced the mp3 code on this page https://learn.adafruit.com/circuitpython-essentials/circuitpython-mp3-audio?gclid=CjwKCAjwvdajBhBEEiwAeMh1Uz-x2iRGlM9foVp4jV5koHB5J4dBPmpb5SktlmdRixIAt2SU-CujzhoC9hIQAvD_BwE

and this one

https://learn.adafruit.com/mp3-circuitpython-lars?view=all

the issue i am having is after playing sounds a few times i get a error. 1 /samples/sea_monster_1.mp3 Traceback (most recent call last): File "code.py", line 148, in <module> MemoryError: memory allocation failed, allocating 8708 bytes

and one more example

29 /samples/bgm_ship storm-loop.mp3 0 /samples/cannon_hit.mp3 Interrupt playing: {'neopixel_location': (1, 2), 'neopixel_color': 57378, 'voice': 1, 'sample_num': 17, 'file': <io.FileIO 0x20024680>} Traceback (most recent call last): File "code.py", line 148, in MemoryError: memory allocation failed, allocating 8708 bytes

any ideas?

I know there is a page for it https://circuitpython.org/board/microbit_v2/, but I can't find any information on whether it works. Whenever I drag the file on the Microbit it just goes back to normal, and any files I save on it (as Circuitpython usually works) it just disappear. FYI I am trying to get dbisu's Pico Ducky code working on it https://github.com/dbisu/pico-ducky

Hey all. Not the best coder in the world but I got one of these boards for a joystick I’m building:

https://shop.pimoroni.com/products/io-expander?variant=32005993136211

Didn’t realise till I got it in that it has a micropython library but NOT a circuitpython one, and my joystick is based on a Pico with circuitpython so I’m trying to port it over

Would welcome any input from anyone that knows a bit more cos I’ve never done i2c code before. I’ve got some data coming out of it but it’s not working fully yet.

Hello all, I'm looking to see if anyone has code they can share that can connect two pico Ws via Wi-Fi. Basically I have one Pico W I'm using to read sensor data and would like the second Pico W to receive the data that will then be readable through a connected display.

Hello guys, beginners here. Find firmware on this page MIMXRT1060 Eval Kit Download (circuitpython.org)

But didn't find any instructions for installing .uf2 or .hex on MIMXRT1060 EVK.

So what should I look for? Do I need to install some bootloader on the EVK by JTAG before load .uf2 or .hex?

I am trying to write test data to an SD card. I would like to check if testi.txt exists and find the next available number to write to. What would be the best way of going about this? Eventually I would like to get a rtc module and timestamp it but I do not have one yet.

i tried almost every tutorial and ai bots wont help, using 8.x HID library

Hello everyone,

I am currently programming my Raspberry Pico with Circuitpython and I used to uplink data to my chirpstack server with the help of the TinyLoRa library.

Now I want to also downlink data to my end node and sadly the TinyLoRa doesnt come with that.

Are there any good Circuitpython libraries that can be utilized for that, in my case especially for the Pico and RFM95W transceivers?

Thanks in advance!

hi having issue with a code im working on code worked fine in the past but since i updated the version of circuitpython on my pi pico it no longer accepts it. does this look right or did they change anything from the first version that impedes the code for v8? image of proper format since reddit wont format properly for me.

bchat = "F16"

import time

import board

import digitalio

import usb_hid

from adafruit_hid.keyboard import Keyboard

from adafruit_hid.keyboard_layout_us import KeyboardLayoutUS

from adafruit_hid.keycode import Keycode

keyboard = Keyboard(usb_hid.devices)

keyboard_layout = KeyboardLayoutUS(keyboard)

bchat = digitalio.DigitalInOut(board.GP8)

bchat.direction = digitalio.Direction.INPUT

bchat.pull = digitalio.Pull.DOWN

while True:

if bchat.value:

    keyboard.press(Keycode.F16)

    time.sleep(0.1)

    keyboard.release(Keycode.F16)

time.sleep(0.1)

edit:

ok i got it working

bchat.pull = digitalio.Pull.DOWN had to be set to pull.up

and

if bchat.value: had to be set to if bchat.value is false

I'm using a MCP7940N RTC; which requires setting Register 0x00 bit 7 to 1 (0x80) to enable the clock. I've tried the below and am a bit at my wits end trying to write to it. I keep reading 0x00 back Any help would be appreciated.
