History

Sascha bf67abb046 Fixed usb read loops not reading until timeout (#16827 ) * the size variable was redeclared (hiding the variable of the outside scope) and therefore the while check was always false, so the compiler just removed the do while loop, but it would be better to read all data and only exit the task, after this is done		2022-04-10 00:27:02 +02:00

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. 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.
