MK32 - Simple BLE keyboard for ESP32

Note: Currently tested and working on esp-idf v4.0.
MK32 is a BLE keyboard firmware for ESP32 Microcontrollers,designed to be relativley easily customizable.
Please refer to the MK32 Wiki page for information about building your own keyboard. Also note that this repository is not heavily maintained.

Many thanks to:

• Benjamin Aigner for his work on implementing HID over BLE on the ESP32: https://github.com/asterics/esp32_mouse_keyboard.
• Neil Kolban for his great contributions to the ESP32 SW (in particular the Bluetooth support): https://github.com/nkolban
• QMK for their layouts and inspiration for this project: https://github.com/qmk/qmk_firmware/

Features:

• Split Keyboards
• I2C/SPI displays
• Customizable layouts
• Macros
• Rotary Encoders (With customizable encoder commands)
• Battery Monitoring
• Power Management
• Basic plugin support

To-do:

• Refactor some bad coding habits (magic numbers etc, sorry I started this project when I had 0 experience!).
• Update esp-idf version to v4.1.
• Plugin API support(Implemented):
  • Currently only one plugin can run at a time (to modify).
• More than 2 pads with espnow (currently supports 2 pads) - Optional.
• Connection switching.
• Modify keymap via webserver:
  • Functions for storing (and reading) AP data on flash complete.
  • Starting web server from plugin complete.
  • need to create proper web GUI for keymap modifications.
• Wifi manager:
  • Add plugin for adding AP.
  • Functions for storing (and reading) AP from flash done.
  • ESPNOW does not work if wifi AP is not on the same channel (Problematic for ESPNOW Based split boards).
