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/core>


Updates
-------
#### 2017/05/30
Fixed **Modifier/Layer key stuck** problem. See this wiki entry. <https://github.com/tmk/tmk_keyboard/wiki/FAQ-Keymap#modifierlayer-stuck> If you need old keymap behaviour for some reason define `NO_TRACK_KEY_PRESS` in your `config.h`.

This is virtually equivalent to QMK `PREVENT_STUCK_MODIFIERS`. <https://github.com/qmk/qmk_firmware/pull/182>

#### 2017/01/11
Changed action code for `ACTION_LAYER_MODS` and this may cause incompatibility with existent shared URL and downloaded firmwware of keymap editor. If you are using the action you just have to redefine it on keymap editor. Existent keymap code should not suffer.

#### 2016/06/26
Keymap framework was updated. `fn_actions[]` should be defined as `action_t` instead of `uint16_t`. And default code for keymap handling is now included in core you just need define `uint8_t keymaps[][MATRIX_ROWS][MATRIX_COLS]` and `action_t fn_actions[]`.

#### 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`.
