Stefan Kerkmann c68e4dec10 [Core] suspend: suppress wake up keypress (#23389)
* suspend: suppress wake up keypress

Waking the host from suspend is done by pressing any key on the
keyboard, the regular key codes assigned to the keys are not important
and must not be sent - otherwise they usually end up in password prompts
as ghost characters that have to be deleted again. This commit adds
suppression for all keys pressed at the time of wake up. Once a key is
released it functions as a regular key again.

* suspend: update wake up matrix after wake up delay

If USB_SUSPEND_WAKEUP_DELAY is set, the keyboard sleeps during wake up -
which can be up to multiple seconds. To handle key presses and releases
in that time frame we have to handle the following cases:

1. Key not pressed before suspend, and not pressed after wakeup → do
   nothing (normal case).
2. Key not pressed before suspend, but pressed after wakeup → set the
   wakeup_matrix bit to 1 (so that the press and release events would be
   suppressed).
3. Key pressed before suspend, but not pressed after wakeup → do nothing
   (the release event will be generated on the first matrix_task() call
   after the wakeup).
4. Key pressed before suspend, and still pressed after wakeup → do
   nothing (the release event will be generated some time later).

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

Current Version 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 VitePress. 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.

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.
