Adding a new 7" blue EA7013 7inch ESP32 display with 16-bit parallel RGB interface

[eagl1]

Hi,

I just received this 7" blue EA7013 7inch ESP32 display with 16-bit parallel RGB interface. It came with the LVGL demo.

This is the display schematic file: EA7013.pdf

I tried to modify the pin arrangement in the object definition to this in this Arduino_GFX_dev_device.h file in the demo code:

Arduino_RGB_Display *gfx = new Arduino_RGB_Display(
    800 /* width */, 480 /* height */, rgbpanel, 0 /* rotation */, true /* auto_flush */);

I set the pin mapping according to the schematic diagram. It didn't work, only the backlight worked:

What I'm missing here ?
