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. 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.
