class adafruit_ssd1306.SSD1306_I2C(*args: Any, **kwargs: Any)

I2C class for SSD1306

Parameters:

  • width – the width of the physical screen in pixels,

  • height – the height of the physical screen in pixels,

  • i2c – the I2C peripheral to use,

  • addr – the 8-bit bus address of the device,

  • external_vcc – whether external high-voltage source is connected.

  • reset – if needed, DigitalInOut designating reset pin

write_cmd(cmd: int) → None

Send a command to the I2C device

write_framebuf() → None
