class adafruit_ssd1306.SSD1306_I2C(width, height, i2c, *, addr=60, external_vcc=False, reset=None, page_addressing=False)

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)

Send a command to the I2C device

write_framebuf()

Blast out the frame buffer using a single I2C transaction to support hardware I2C interfaces.

class adafruit_ssd1306.SSD1306_SPI(width, height, spi, dc, reset, cs, *, external_vcc=False, baudrate=8000000, polarity=0, phase=0, page_addressing=False)

SPI class for SSD1306

Parameters:

• width – the width of the physical screen in pixels,
• height – the height of the physical screen in pixels,
• spi – the SPI peripheral to use,
• dc – the data/command pin to use (often labeled “D/C”),
• reset – the reset pin to use,
• cs – the chip-select pin to use (sometimes labeled “SS”).
