Greetings. I have the 480 x 272 TFT with capacitive touch screen version of this board. AKA ESP32-4827S043.
It’s been a bit of a bear to get the lvgl demo’s running but just managed to do so, except, the touch screen isn’t yet working. One thing at a time.
Attached is a zip file containing the code and config file used.
Note, you will have to replace the Arduino_ESP32RGBPanel* rgbpanel = new Arduino_ESP32RGBPanel( configuration with the correct one for your 800 *480 panel.
Also, copying the demo and examples folder as given here and following the README.md file here was needed.
Note that I did have to explicitly include the path to lv_demos.h as seen in the sketch.
File touch.h will also have to be edited to select the correct driver for your touch panel (and possibly install the needed library).
My environment:
DUT: Sunton ESP32-4827S043C (capacitive touch screen, ESP32-S3-N16R8).
Arduino IDE: Version: 2.1.1, Date: 2023-06-30T16:00:43.829Z, CLI Version: 0.32.3

Hope this helps.
If anyone knows how to modify the sketch to get the touch screen working, I’d appreciate the info! On this version of the board it uses the GT911 driver.
