Quad SPI AMOLED Displays
========================

:description: Instructions for setting up quad SPI AMOLED displays.
:image: t4-s3.jpg
.. _qspi_amoled:
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.

# Example minimal configuration entry
display:
- platform: qspi_amoled
model: RM690B0
data_rate: 80MHz
spi_mode: mode0
dimensions:
width: 450
height: 600
offset_width: 16
color_order: rgb
invert_colors: false
brightness: 255
cs_pin: GPIOXX
reset_pin: GPIOXX
enable_pin: GPIOXX
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 ````, ``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.
