Quad SPI AMOLED Displays¶
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 quad SPI bus interface must be configured.

Configuration variables:¶
model (Required): One of
RM67162
orRM690B0
.cs_pin (Required, Pin Schema): The chip select pin.
reset_pin (Optional, Pin Schema): The RESET pin.
enable_pin (Optional, Pin Schema): The display enable pin.
brightness (Optional, int): A brightness value in the range 0-255
update_interval (Optional, 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 Display Pages.
id (Optional, ID): Manually specify the ID used for code generation.
color_order (Optional): Should be one of
rgb
(default) orbgr
.- 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.
- dimensions (Required): Dimensions of the screen, specified either as width x height (e.g
rotation (Optional): Rotate the display presentation in software. Choose one of
0°
,90°
,180°
, or270°
.transform (Optional): Transform the display presentation using hardware. All defaults are
false
. This option cannot be used withrotation
.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
or1MHz
.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, lambda): The lambda to use for rendering the content on the display. See Display Rendering Engine for more information.
