:description: Instructions for setting up SSD1306 OLED display drivers.
:image: ssd1306.jpg
.. _ssd1306-i2c:
Over I²C
--------
The ``ssd1306_i2c`` display platform allows you to use
SSD1306 (`datasheet <https://cdn-shop.adafruit.com/datasheets/SSD1306.pdf>`__,
`Adafruit <https://www.adafruit.com/product/326>`__), SSD1305 (`datasheet <https://cdn-shop.adafruit.com/datasheets/SSD1305.pdf>`__),
SH1107 (`datasheet <https://cdn-learn.adafruit.com/assets/assets/000/094/580/original/SH1107_datasheet.pdf>`__,
`Adafruit <https://www.adafruit.com/product/4650>`__)
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 ESPHome. Note that this component is for displays that are connected via the :ref:`I²C Bus <i2c>`.
If your SSD1306/SSD1305 or SH1106 is connected via the 4-Wire :ref:`SPI bus <spi>`, see :ref:`ssd1306-spi`.

SSD1306 OLED Display
Connect D2 to the SCL pin you chose for the :ref:`I²C Bus <i2c>`, and connect D1 to the SDA pin. 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.
.. code-block:: yaml
# Example configuration entry
i2c:
sda: D1
scl: D2
display:
- platform: ssd1306_i2c
model: "SSD1306 128x64"
reset_pin: D0
address: 0x3C
lambda: |-
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 72x40``
- ``SSD1306 64x48``
- ``SH1106 128x32``
- ``SH1106 128x64``
- ``SH1106 96x16``
- ``SH1106 64x48``
- ``SH1107 128x64``

- ``SSD1305 128x32``
- ``SSD1305 128x64``
- **reset_pin** (*Optional*, :ref:`Pin Schema <config-pin_schema>`): The RESET pin. Defaults to not connected.
- **address** (*Optional*, int): Manually specify the :ref:`I²C <i2c>` address of the display. Defaults to 0x3C.
- **rotation** (*Optional*): Set the rotation of the display. Everything you draw in ``lambda:`` will be rotated
by this option. One of ``0°`` (default), ``90°``, ``180°``, ``270°``.
- **contrast** (*Optional*, percentage): Set display contrast in %. Defaults to ``100%``.
- **brightness** (*Optional*, percentage): Set display brightness in %. Only can be used with SSD1305. Defaults to ``100%``.
- **external_vcc** (*Optional*, boolean): Set this to true if you have the VCC pin connected to an external power supply.
Defaults to ``false``.
- **flip_x** (*Optional*, boolean): Flip the horizontal axis on the screen. Defaults to ``true``.
- **flip_y** (*Optional*, boolean): Flip the vertical axis on the screen. Defaults to ``true``.
- **offset_x** (*Optional*, int): Set this option if some horizontal pixel is missing. Numbers are only allowed between ``0~128``. Defaults to ``0``.
- **offset_y** (*Optional*, int): Set this option if some vertical pixel is missing. Numbers are only allowed between ``0~128``. Defaults to ``0``.
- **invert** (*Optional*, boolean): Invert all pixel state on the display. Defaults to ``false``.
- **lambda** (*Optional*, :ref:`lambda <config-lambda>`): The lambda to use for rendering the content on the display.
See :ref:`display-engine` for more information.
- **update_interval** (*Optional*, :ref:`config-time`): The interval to re-draw the screen. Defaults to ``1s``.
- **pages** (*Optional*, list): Show pages instead of a single lambda. See :ref:`display-pages`.
- **id** (*Optional*, :ref:`config-id`): Manually specify the ID used for code generation.
.. note::
To speed up the display update process you can select higher I²C frequencies.
.. _ssd1306-spi:
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 ESPHome. 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 :ref:`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.
