AN4/C1INB/RPB2/RB4.
The processor pin associated with the data sent to the HEADPHONES connector is pin #13 –
AN3/C2INA/RPB3/RB3.
6.3.7 Display
The board has a 128x64 pixels OLED display which uses SSD1306 driver. The I2C slave address of
the display is 0111100b.
The SSD1306 embeds with contrast control, display RAM and oscillator, which reduces the number
of external components and power consumption. It has 256-step brightness control.
Data/Commands are sent from general MCU through the hardware selectable 6800/8000 series
compatible Parallel Interface, I2C interface or Serial Peripheral Interface. It is suitable for many
