Pimoroni PGA Boilerplate
This repository is intended to provide a baseline MicroPython build for PGA2040 and PGA2350, in addition to being a minimal example of how you might set up your own custom MicroPython flavour to support your PGA-based project.
Use this repository as a boilerplate to set up your own project, and GitHub actions should automatically handle building MicroPython for you.
Contents
- pga2040 - MicroPython and Pico SDK board definitions for PGA2040
- pga2350 - MicroPython and Pico SDK board definitions for PGA2350, with PSRAM variant
- modules/c/example - An example MicroPython C++ module, demonstrating C class bindings
- modules/py_frozen - Python files intended to be frozen into the firmware
- modules/py_littlefs - Python files intended to be visible/editable in the LittleFS user filesystem
- modules/default.py - The MicroPython manifest file, for specifying frozen libs
- modules/default.txt - The dir2uf2 LittleFS manifest file, for specifying included files
- modules/default.cmake - The MicroPython USER_C_MODULES file, for specifying included C/C++ modules
