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
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 - 120 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.
