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:

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

What I'm missing here ?

I did not have this display in hand. In general, try adjust the parameters according to the display data sheet.

I'm trying but it's not working until this moment. Only the backlight worked.

I know it will need more time to get it to work eventually.

[eagl1]

I got it to work in ESP-IDF platform, easy RGB example code, only changed the RGB parameters and worked perfectly.

But I don't know what is the difference between your RGB code and the one in the ESP-IDF plattform ? it's almost the same code.

I have a question, if I wanted to copy Arduino_ESP32RGBPanel library and use it in TFT_eSPI library. What requirements I have to use along with it ?
