If you need to work with the project files locally, you can create a Python virtual environment:
python -m venv venv
source venv/bin/activate
python -m pip install -r requirements.txt
This package uses the following packages as dependencies:
- https://github.com/CoreElectronics/CE-PiicoDev-Unified/blob/main/PiicoDev_Unified.py
- https://github.com/CoreElectronics/CE-PiicoDev-VEML6030-MicroPython-Module/blob/main/PiicoDev_VEML6030.py
- https://github.com/joeky888/awesome-micropython-lib.git
- https://github.com/danjperron/PicoAudioPWM.git
Prerequisites: MicroPython must already be installed on your Raspberry Pi Pico. Installation instructions can be found at https://micropython.org/download/RPI_PICO/
Note: Connecting to Raspberry Pi Pico on Linux may sometimes be challenging. Check linux.md for troubleshooting tips.
mpremote documentation: https://docs.micropython.org/en/latest/reference/mpremote.html
Install dependencies to Pico:
mpremote mip install github:CoreElectronics/CE-PiicoDev-Unified/PiicoDev_Unified.py
mpremote mip install github:CoreElectronics/CE-PiicoDev-VEML6030-MicroPython-Module/PiicoDev_VEML6030.py
mpremote mip install github:joeky888/awesome-micropython-lib/Audio/chunk.py
mpremote mip install github:joeky888/awesome-micropython-lib/Audio/wave.py
mpremote mip install github:danjperron/PicoAudioPWM/myDMA.py
mpremote mip install github:danjperron/PicoAudioPWM/myPWM.py
mpremote mip install github:danjperron/PicoAudioPWM/wavePlayer.pyCopy sources to Pico:
mpremote fs cp -r src/* :Verify installation:
- Run
mpremote lsto make sure everything is copied over (you may need to restart the Pico to pick up changes) - Run
mpremote dfto check available space on the Pico
When using your own sounds, make sure they are 16-bit WAV files with a 16000 Hz sample rate. You can use Kwave (open source audio editor) to convert files.
Recovery: If you copied a corrupted file and your Pico seems to be bricked, you can flash it with the official Raspberry Pi memory reset: flash_nuke.uf2
