|
The ``xpt2046`` touchscreen platform allows using the touch screen controllers
|
|
based on the XPT2046 chip
|
|
(`datasheet <https://datasheetspdf.com/pdf-file/746665/XPTEK/XPT2046/1>`__,
|
|
`AZ-Delivery`_) with ESPHome. Many cheap LCD displays contain this controller.
|
|
The :ref:`SPI <spi>` is required to be set up in your configuration for this sensor to work.

Configuration variables:
|
|
------------------------
|
|
The configuration is made up of two parts: The touch screen component, and optional individual binary sensors.
|
|
|
|
Base Configuration:
|
|
|
|
- **id** (*Optional*, :ref:`config-id`): Set the ID of this sensor.
|
|
|
|
- **cs_pin** (*Optional*, :ref:`Pin Schema <config-pin_schema>`): The chip select pin.
|
|
Often marked ``T_CS`` on the board.
|
|
|
|
- **interrupt_pin** (*Optional*, :ref:`Pin Schema <config-pin_schema>`): The touch detection pin.
|
|
Often marked ``T_IRQ`` on the board. If not specified the component will use polling
|
|
via SPI. This key is renamed from **irq_pin**
|
|
|
|
- **update_interval** (*Optional*, :ref:`config-time`): The interval to check the
|
|
sensor. If ``interrupt_pin`` is specified the touch will be detected nearly instantaneously and this setting
|
|
will be used only for the release detection. Defaults to ``50ms``.
|
|
|
|
- **threshold** (*Optional*, int): The value to detect the touch or release. Defaults to ``400``.
|
|
|
|
|
|
- **calibration_x_min** (*Depricated*): This value is moved to the ``calibration`` values
|
|
|
|
- **calibration_x_max** (*Depricated*): This value is moved to the ``calibration`` values.
|
|
|
|
- **calibration_y_min** (*Depricated*): This value is moved to the ``calibration`` values.
|
|
|
|
- **calibration_y_max** (*Depricated*): This value is moved to the ``calibration`` values.
|
|
|
|
- **swap_x_y** (*Depricated*): This value is moved to the ``transform`` values as ``swap_xy`` see :ref:`config-touchscreen`.
|
|
|
|
- **report_interval** (*Depricated*): This interval is removed in favor of the ``update_interval``.
|
|
|
|
- All other options from :ref:`config-touchscreen`.
