SSD1306 OLED Display over SPI
|
|
|
|
|
=============================
|
|
|
|
|
|
|
|
|
|
The ``ssd1306_spi`` display platform allows you to use
|
|
|
|
|
SSD1306 (`datasheet <https://cdn-shop.adafruit.com/datasheets/SSD1306.pdf>`__, `Adafruit <https://www.adafruit.com/product/326>`__)
|
|
|
|
|
and SH1106 (`datasheet <https://www.elecrow.com/download/SH1106%20datasheet.pdf>`__, `electrodragon <https://www.electrodragon.com/product/1-3-12864-blue-oled-display-iicspi/>`__)
|
|
|
|
|
displays with esphomelib. Note that this component is for displays that are connected via the 4-Wire :ref:`SPI bus <spi>`.
|
|
|
|
|
If your SSD1306 or SH1106 is connected via the :ref:`I²C Bus <i2c>`, see :doc:`ssd1306_i2c`.

Connect D0 to the CLK pin you chose for the :ref:`SPI bus <spi>`, 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.
