This project provides MicroPython board definition and support modules for the Adafruit RP2040-based MacroPad board.
- OLED Display - SH1106 driver using FrameBuffer class over SPI
- Neopixel - RP2040 version of the ESP32 NeoPixel class using the PIO SM
- I2C, SPI and Pin definitions for (reasonable) defaults based on schematic
- Half-baked key debouncing
- Quadrature Encoding for the rotary encoder switch
Interim USB HID support comes from this RPi forum post
Follow the README in the micropython/ports/rp2 directory to get build fundamentals working.
Once you can build the GENERIC board successfully, you can build the MacroPad version here either from the ports/rp2 directory or this directory.
You will need to apply a patch to the ports/rp2/Makefile to support out-of-tree board definitions (like this one).

After flashing the MicroPython UF2 file, you can run a simple demo/example that illustrates basic functionality:
