Models
|
|
------
|
|
This display driver supports AMOLED displays with quad SPI interfaces.
|
|
|
|
This driver has been tested with the following displays:
|
|
|
|
- Lilygo T4-S3
|
|
- Lilygo T-Display S3 AMOLED
|
|
|
|
Usage
|
|
-----
|
|
This component requires an ESP32 and the use of
|
|
ESP-IDF. PSRAM is a requirement due to the size of the display buffer. A :ref:`quad SPI bus <spi>` interface must be configured.

Configuration variables:
|
|
************************
|
|
|
|
- **model** (**Required**): One of ``RM67162`` or ``RM690B0``.
|
|
- **cs_pin** (**Required**, :ref:`Pin Schema <config-pin_schema>`): The chip select pin.
|
|
- **reset_pin** (*Optional*, :ref:`Pin Schema <config-pin_schema>`): The RESET pin.
|
|
- **enable_pin** (*Optional*, :ref:`Pin Schema <config-pin_schema>`): The display enable pin.
|
|
- **brightness** (*Optional*, int): A brightness value in the range 0-255
|
|
- **update_interval** (*Optional*, :ref:`config-time`): The interval to re-draw the screen. Defaults to ``5s``.
|
|
- **auto_clear_enabled** (*Optional*, boolean): Whether to automatically clear the display in each loop (''true'', default),
|
|
or to keep the existing display content (must overwrite explicitly, e.g., only on data change).
|
|
- **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.
|
|
- **color_order** (*Optional*): Should be one of ``rgb`` (default) or ``bgr``.
|
|
- **dimensions** (**Required**): Dimensions of the screen, specified either as *width* **x** *height* (e.g ``320x240``) or with separate config keys.
|
|
- **height** (**Required**, int): Specifies height of display in pixels.
|
|
- **width** (**Required**, int): Specifies width of display.
|
|
- **offset_width** (*Optional*, int): Specify an offset for the x-direction of the display, typically used when a display is smaller than the maximum supported by the driver chip. Default is 0
|
|
- **offset_height** (*Optional*, int): Specify an offset for the y-direction of the display. Default is 0.
|
|
|
|
- **rotation** (*Optional*): Rotate the display presentation in software. Choose one of ``0°``, ``90°``, ``180°``, or ``270°``.
|
|
- **transform** (*Optional*): Transform the display presentation using hardware. All defaults are ``false``. This option cannot be used with ``rotation``.
|
|
|
|
- **swap_xy** (*Optional*, boolean): If true, exchange the x and y axes.
|
|
- **mirror_x** (*Optional*, boolean): If true, mirror the x axis.
|
|
- **mirror_y** (*Optional*, boolean): If true, mirror the y axis.
|
|
- **data_rate** (*Optional*): Set the data rate of the SPI interface to the display. One of ``80MHz``, ``40MHz``, ``20MHz``, ``10MHz`` (default), ``5MHz``, ``2MHz`` or ``1MHz``.
|
|
- **spi_mode** (*Optional*): Set the mode for the SPI interface to the display. Default is ``MODE0``.
|
|
- **invert_colors** (*Optional*): With this boolean option you can invert the display colors.
|
|
- **lambda** (*Optional*, :ref:`lambda <config-lambda>`): The lambda to use for rendering the content on the display.
|
|
See :ref:`display-engine` for more information.
