Keyboard report should be checked if its transfer finishs successfully. Otherwise key stroke can be missing when other key event occurs before the last report transfer is done. Boot protocol 10ms interval probably causes this problem in case it receives key events in a row within the period. NKRO protocol suffers less or nothing due to its interval 1ms. |

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
.
