The ``gt911`` touchscreen platform allows using the touch screen controllers based on the gt911 chip with ESPHome.
|
|
The :ref:`I²C <i2c>` is required to be set up in your configuration for this touchscreen to work.
|
|
|
|
This controller is used in the Espressif ESP32-S3-BOX-3 and the m5paper;

Base Touchscreen Configuration
|
|
------------------------------
|
|
|
|
.. code-block:: yaml
|
|
|
|
# Example configuration entry
|
|
touchscreen:
|
|
platform: gt911
|
|
id: my_touchscreen
|
|
interrupt_pin: GPIOXX
|
|
|
|
Configuration variables:
|
|
************************
|
|
|
|
- **id** (*Optional*, :ref:`config-id`): Manually set the ID of this touchscreen.
|
|
- **interrupt_pin** (**Required**, :ref:`Pin Schema <config-pin_schema>`): The touch detection pin.
|
|
- **rotation** (*Optional*): Set the rotation of the touchscreen. By default this will be set to match the display associated with the touchscreen, but this allows more control. Choices are ``0``, ``90``, ``180`` and ``270``.
|
|
|
|
- All other options from :ref:`Touchscreen <config-touchscreen>`.
|
|
|
|
Binary Sensor
|
|
-------------
|
|
|
|
In addition to touch areas on the screen configured through the :ref:`Touchscreen <config-touchscreen>` component,
|
|
the gt911 supports up to four buttons located outside of the normal touchscreen area.
|
|
On the ESP32-S3-BOX-3 the red circle below the display is such a button.
|
|
A binary sensor can be configured to react to touching these buttons.
|
|
|
|
.. code-block:: yaml
|
|
|
|
# Example configuration entry
|
|
binary_sensor:
|
|
- platform: gt911
|
|
name: "Home"
|
|
index: 0
|
|
|
|
Configuration variables:
|
|
************************
|
|
|
|
- **gt911_id** (*Optional*, :ref:`config-id`): Manually specify the ID of the touchscreen.
|
|
- **index** (*Optional*, int): Internal index of the touch button, between 0 and 3. The default is 0.
|
|
|
|
- All other options from :ref:`Binary Sensor <config-binary_sensor>`.
