The firmware is written in C++ and uses the PlatformIO build system. It is recommended to use the VSCode extension for PlatformIO, but you can also use the command line interface. To select your target (V1 or V2), press Ctrl+Shift+P (View -> Command Palette) in VSCode, search for "PlatformIO: Pick project environment" and select either v1 or v2. You can then build and upload the firmware using the buttons in the bottom bar of VSCode (you can also assign shortcuts).
You may find some options from the platformio.ini file useful for debugging and development, such as the blackbox or debug print statements.
This project is still in the early stages of making the source available. If you feel like something is missing in order to make this repo accessible, please open an issue or ask in the discussion forum.
