In #18631 some IN notification callbacks that were doing nothing were removed, which should be a valid thing to do (ChibiOS HAL checks the `in_cb` and `out_cb` pointers for being non-NULL before invoking those optional callbacks). However, it turned out that some less popular USB LLDs (KINETIS and MIMXRT1062) have their own checks for those pointers, and (incorrectly) skip the ChibiOS callback handling when those pointers are NULL, which breaks the code for the `USB_USE_WAIT` configuration option (the waiting thread never gets resumed if the corresponding callback pointer is NULL). Add those dummy callbacks again (but use a single function for all of them instead of individual ones for each endpoint); this restores the KINETIS and MIMXRT1062 boards to the working state while the LLDs are getting fixed.
THIS IS THE DEVELOP BRANCH
Warning- This is the develop branch of QMK Firmware. You may encounter broken code here. Please see Breaking Changes for more information.
Quantum Mechanical Keyboard Firmware
This is a keyboard firmware based on the tmk_keyboard firmware with some useful features for Atmel AVR and ARM controllers, and more specifically, the OLKB product line, the ErgoDox EZ keyboard, and the Clueboard product line.
Documentation
The docs are powered by Docsify and hosted on GitHub. They are also viewable offline; see Previewing the Documentation for more details.
You can request changes by making a fork and opening a pull request, or by clicking the "Edit this page" link at the bottom of any page.
Supported Keyboards
The project also includes community support for lots of other keyboards.
Maintainers
QMK is developed and maintained by Jack Humbert of OLKB with contributions from the community, and of course, Hasu. The OLKB product firmwares are maintained by Jack Humbert, the Ergodox EZ by ZSA Technology Labs, the Clueboard by Zach White, and the Atreus by Phil Hagelberg.
