Reimplements WPM feature to be smaller & precise (#13902)
* Reimplements WPM feature.

 - Now calculates exact WPM over the last up to three seconds of typing.
 - WPM_SMOOTHING removed, as it's no longer needed.
 - WPM_SAMPLE_SECONDS added, to specify how long a period to average WPM
   over, set to 5 seconds by default.
 - WPM_SAMPLE_PERIODS added, to specify how many sampling buffers we'll
   use.  Each one uses one extra byte of space.  Having more will lead
   to smoother decay of WPM values.  Defaults to 50 (we're saving so
   many bytes of firmware space I felt like being extravagent, and this
   change is still a big size saving overall)
 - WPM_UNFILTERED option added (defaults to unset), which disables all
   filtering within the WPM feature.  This saves some space in the
   firmware and also reduces latency between typing and the WPM
   calculation measuring it.  (saves 70 bytes in my tests)
 - WPM_LAUNCH_CONTROL added (defaults to unset).  When typing begins
   while the current displayed WPM value is zero, the WPM calculation
   only considers the time elapsed since typing began, not the whole
   WPM_SAMPLE_SECONDS buffer.  The result of this is that the displayed
   WPM value much more rapidly reaches an accurate WPM value, even when
   results are being filtered. (costs 22 bytes in my tests)
 - Updates documentation to reflect changed options.

Saves about 900 bytes, in my tests, compared against the previous implementation,
with default settings.

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 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.
