ESP32-8048S050C

Implementation with FreeRTOS OSAL and LVGL 9.2

Sunton ESP32-S3 800x480 Capacitive touch display

Example using esp-idf 5.2 and the esp_lcd_touch_gt911 and lvgl components.

In gt911_touch_init, a callback is registered to map the measured touch coordinates to display coordinates, see header file for information.

  • Set esp-idf target to ESP32S3, other versions might lack rgb panel support.
  • The supplied sdkconfig.defaults configures SPIRAM, regenerate your sdkconfig if needed.

idf.py set-target esp32s3 idf.py build flash monitor
