Keychron keyboards on Linux + Bluetooth fixes

Here is the best setup (I think so :D) for K-series Keychron keyboards on Linux.

Most of these commands have been tested on Ubuntu 20.04 and should also work on most Debian-based distributions. If a command happens not to work for you, take a look in the comment section.

Make Fn + F-keys work

Keychron Keyboards on Linux use the hid_apple driver (even in Windows/Android mode), both in Bluetooth and Wired modes. By default, this driver uses the F-keys as multimedia shortcuts and you have to press Fn + the key to get the usual F1 through F12 keys.

Sample 3 leds misc device

Description:

  • Write 1 to character device files to enable blinky
  • Write 0 to character device files to disable blinky
  • Read from character device files to get status led ON or OFF
  • Using led_config to setup and collect time inteval on each led

Sample is tested on:

  • OpenSTLinux Development package, kernel version 5.10.10
  • STM32MP157C-DK2 board
  • Using 2 built-in leds LD6 (GPIOA13) + LD7 (GPIOH7) and an external led connected to GPIOF3

STM8s - SDCC patch
Not finished - 20 Jan 2002 - checkpoint (Steve Kenton)
This is a sorted (ignoring leading '_') list of the SDCC library.
Sources are in ~sdcc/device/lib/*.c and ~sdcc/device/include/*.h.
Except where denoted with MACRO these are implemented as functions.
Internal function calls are generated by the compiler to implement
IEEE floating point, etc. They are not normally called directly.
isalnum - character classification - #include <ctype.h> - all ports
char isalnum (unsigned char c); MACRO
