* STM32 EEPROM Emulation
- Added EEPROM emulation libaries from libmaple and Arduino_STM32. https://github.com/rogerclarkmelbourne/Arduino_STM32 and https://github.com/leaflabs/libmaple.
- Renamed teensy EEPROM library and added conditional selection of library.
- Remapped EEPROM memory map for 16 byte blocks (as is with STM32f3xx MCUs).
- Added EEPROM initialization in main.c of Chibios.
- Added EEPROM format to clear the emulated pages when EEPROM is marked as invalid.
* Fixed ifdef
Updated MiniDox split_util.h and eeprom files to reflect this change.
I recommend adding this to any split board that used these files, my changes will not effect them currently.
This protocol breaks out "duplicate" keys into their own entry in the packet so that more complicated logic can be done on the software side, including support for additional languages and alternative theories.
