SPI/I2C Displays

MK32 supports the use of I2C and SPI displays using Neil Kobaln's u8g2 adaptation.

Enabling an I2C Display:

in keyboard_config.h:
- Uncomment #define OLED_ENABLE.
- Set your display's rotation #define LANDSCAPE\DEG90\DEG180\DEG270.
- Set your OLED_SDA_PIN and OLED_SCL_PIN.
- If you are not using a 128x64 I2C display, in components/u8g2_OLED/oled_tasks.c in function init oled change u8g2_Setup_ssd1306_i2c_128x64_noname_f to the function that fits you your display.
  You might need to modify the display functions themselves to fit your resolution so please refer to the u8g2 reference manual.

Enabling an SPI Display:

**Will be updated soon for easier implementation, for now can you check out Neil Kolban's SPI example (linked in his repository) to adapt.
