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](protocol/chibios/README.md). Chibios protocol supports Cortex-M such as STM32 and Kinetis.

Features
--------
These features can be used in your keyboard.

* Multi-layer Keymap  - Multiple keyboard layouts with layer switching
* Mouse key           - Mouse control with keyboard
* System Control Key  - Power Down, Sleep, Wake Up and USB Remote Wake up
* Media Control Key   - Volume Down/Up, Mute, Next/Prev track, Play, Stop and etc
* USB NKRO            - 248 keys(+ 8 modifiers) simultaneously
* PS/2 mouse support  - PS/2 mouse(TrackPoint) as composite device
* Keyboard protocols  - PS/2, ADB, M0110, Sun and other old keyboard protocols
* User Function       - Customizable function of key with writing code
* Macro               - Very primitive at this time
* Keyboard Tricks     - Oneshot modifier and modifier with tapping feature
* Debug Console       - Messages for debug and interaction with firmware
* Virtual DIP Switch  - Configurations stored EEPROM(Boot Magic)
* Locking CapsLock    - Mechanical switch support for CapsLock
* Breathing Sleep LED - Sleep indicator with charm during USB suspend
* Backlight           - Control backlight levels

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`.
