MicroPython Board Support for Adafruit MacroPad

This project provides MicroPython board definition and support modules for the Adafruit RP2040-based MacroPad board.

Support

• 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

Missing

• Quadrature Encoding for the rotary encoder switch

USB HID

Interim USB HID support comes from this RPi forum post

Build

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).

 ifdef USER_C_MODULES
 CMAKE_ARGS += -DUSER_C_MODULES=${USER_C_MODULES}
 endif

+ifdef BOARD_DIR
+CMAKE_ARGS += -DMICROPY_BOARD_DIR=${BOARD_DIR} -DPICO_BOARD_HEADER_DIRS=${BOARD_DIR}
+endif

Demo

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