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>

|
-------
|
|
#### 2016/02/10
|
|
flabbergast's Chibios protocol was merged from <https://github.com/flabbergast/tmk_keyboard/tree/chibios>. See [protocol/chibios/README.md](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`.
