#Building

You will need to have arm-none-eabi-gcc available on your $PATH, and check out the library submodules with:

git submodule update --init --recursive

Once you've done this, the Makefile in the root of this repo can be used to build the firmware.

make

You can also conveniently flash the built firmware to a mounted UF2 partition by using make flash.

The CFLAGS flag can be set to pass additional build flags to GCC. For example, if you have a mainboard before r9 and therefore require a build that uses the older pinout, you can run make CFLAGS="-DLEGACY_PINOUT".

#Development

  Add: [
    -ferror-limit=0,
