TMK Keyboard Firmware Core Library

This is a keyboard firmware library with some useful features for Atmel AVR and Cortex-M.

Source code is available here: https://github.com/tmk/tmk_keyboard/tree/master/tmk_core

Updates

2016/02/10

flabbergast's Chibios protocol was merged from https://github.com/flabbergast/tmk_keyboard/tree/chibios. See protocol/chibios/README.md. Chibios protocol supports Cortex-M such as STM32 and Kinetis.

Debugging

Use PJRC's hid_listen to see debug messages. You can use the tool for debug even if firmware use LUFA stack.

You can use xprintf() to display debug info on hid_listen, see common/xprintf.h.
