[Keyboard] Added support for ErgoDox with STM32 Microcontroller (#5398)
* Began Work On STM32 Ergodox
Changes to be committed:
new file: keyboards/ergodox_stm32/config.h
new file: keyboards/ergodox_stm32/rules.mk
* test
* Now it compile. Not linking thou
* Screw this Linker. It links now!
* Blinkly Keyboard
* bootloader test code
* Working on matrix / i2c stuff
* Progress (LED Blink)
* Progress on MCP_23017 Status Flag
* [WIP]
* update
* Works! Remeber to change back the bootloader address when the new bootloadrer is ready.
* Time to go debug the i2c
* Finally, it now works with PCB Rev 1.0.2
* updated for rev.2 pcb
* minor compilation fix
* Why when debugger is enabled then everything works.
* Remeber to call init functions.
* Update arm i2c driver to support STM32F103 series device.
* fix include once header. Replaced with #pragma once.
* complication test
