Keybon - Adaptive Macro Keyboard

Keybon is a macro keyboard with configurable layouts and functions. Integrated into each of its nine tactile buttons is a 0.66” OLED screen. Depending on which app is active on the connected computer, Keybon switches to the suitable key layout thanks to its companion software.

Instructions

1. Download the USB bootloader: https://github.com/rogerclarkmelbourne/STM32duino-bootloader

   Connect a USB-to-Serial adapter to the TX/RX pins of your board. Close the BOOT0 jumper before applying power.

   Flash the USB bootloader to the STM32 via the STM32 flasher: https://www.st.com/en/development-tools/flasher-stm32.html

2. Install the required Arduino libraries listed in the keybon.ino file

   Important: Adafruit_GFX_Library version 1.7.5 must be installed (dependencies for newer versions are incompatible with the STM32)

   Add the following lines to the Adafruit_SSD1306 library (in Arduino\libraries\Adafruit_SSD1306\Adafruit_SSD1306.cpp)

   else if ((WIDTH == 128) && (HEIGHT == 48)) {
   comPins = 0x12;
     contrast = (vccstate == SSD1306_EXTERNALVCC) ? 0x9F : 0xCF;
   }

3. Install STM32 support for the Arduino IDE: https://github.com/rogerclarkmelbourne/Arduino_STM32

   Install the corresponding drivers: https://github.com/rogerclarkmelbourne/Arduino_STM32/tree/master/drivers

4. Compile and upload the Arduino sketch:
