Handlebar Controller (Software)

Software development steps

  1. Install Arduino IDE and ESP32 library from scratch
  2. Bluetooth Keyboard 
  3. Rotary encoder connexion
  4. Configuration file with Inifile on SDCard
  5. Display with OLED shield

Step 1 – Install Arduino IDE and ESP32 library from scratch

S1.1 Download Arduino IDE from https://www.arduino.cc/en/software

  • Install the current upstream Arduino IDE at the 1.8 level or later. 

S1.2 Install “Expressif ESP32” library https://github.com/espressif/arduino-esp32

as described in https://github.com/espressif/arduino-esp32/blob/master/README.md and https://github.com/espressif/arduino-esp32/blob/master/docs/arduino-ide/boards_manager.md
