Support using a timer for wait_us() on ChibiOS-based boards (#12211)
* Support using a timer for wait_us() on ChibiOS-based boards (#12198)

There are spare GPT timers that can be used to get a more accurate
wait_ms() time. This is required for the matrix scan unselect delay (30µs)
to be shorter than the system tick rate of 100µs.

This is limited to the maximum GPT duration of 65535 so values above that
will automatically use the previous implementation based on the system
tick.

Using a specific timer means it can't be shared by another thread at the
same time so when wait_us() is called from anything other than the main
thread it will use the system tick implementation too.

Quantum Mechanical Keyboard Firmware

Current Version Build Status Discord Docs Status GitHub contributors GitHub forks

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.

Official Website

qmk.fm is the official website of QMK, where you can find links to this page, the documentation, and the keyboards supported by QMK.
