Color Displays based on ST7701
The DisplayST7701Element enables using ST7701 based TFT color displays in HomeDing based devices.
The ST7701 chip supports the 16-bit graphics display bus from the esp32-s3 processor to transfer in-memory graphics data to the display and uses the SPI bus for configuration.
It is used in the Panel ESP32-4848S040.
Display Brightness Control
TFT displays need a background lightning that is controlled by a GPIO pin configured in
the parameter lightpin
.
The brightness
can be adjusted from 0 to 100.
Rotating the Display
The Display driver may be used in different scenarios with different rotations. The rotation 0
is defined by the default
implementation of the display hardware and may be portrait or landscape. The rotation can be changed to 0, 90, 180 or 270.
