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.
