SSD1306 OLED Display over SPI

The ssd1306_spi display platform allows you to use SSD1306 (datasheet, Adafruit) and SH1106 (datasheet, electrodragon) displays with esphomelib. Note that this component is for displays that are connected via the 4-Wire SPI bus. If your SSD1306 or SH1106 is connected via the I²C Bus, see SSD1306 OLED Display over I²C.

Connect D0 to the CLK pin you chose for the SPI bus, connect D1 to the MOSI pin and DC and CS to some GPIO pins on the ESP. For power, connect VCC to 3.3V and GND to GND. Optionally you can also connect the RESET pin to a pin on the ESP which may improve reliability.

# Example configuration entry

      it.print(0, 0, id(font), "Hello World!");

Configuration variables:

  • model (Required): The model of the display. Options are:
    • SSD1306 128x32 (SSD1306 with 128 columns and 32 rows)
    • SSD1306 128x64
    • SSD1306 96x16
    • SSD1306 64x48
    • SH1106 128x32
    • SH1106 128x64
    • SH1106 96x16
    • SH1106 64x48
  • cs_pin (Required, Pin Schema): The Chip Select (CS) pin.
  • dc_pin (Required, Pin Schema): The DC pin.
  • reset_pin (Optional, Pin Schema): The RESET pin. Defaults to not connected.
  • rotation (Optional): Set the rotation of the display. Everything you draw in lambda: will be rotated by this option. One of (default), 90°, 180°, 270°.
  • external_vcc (Optional, boolean): Set this to true if you have the VCC pin connected to an external power supply. Defaults to false.
  • lambda (Optional, lambda): The lambda to use for rendering the content on the display. See Display Rendering Engine for more information.
  • update_interval (Optional, Time): The interval to re-draw the screen. Defaults to 5s.
  • spi_id (Optional, ID): Manually specify the ID of the SPI Component if you want to use multiple SPI buses.
  • id (Optional, ID): Manually specify the ID used for code generation.
