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.
