ST7262 support?

[DevAnyKR]

I have ESP32-8048S043C.
It works perfectly with Arduino GFX 1.5.x, LVGL 9.x, ESP32 Core 3.x, up to 30FPS.
Lovyan GFX has not been successful yet.
Is ST7262 support possible? its RGB565 panel

Hi,
I'll try to see the specs of this module, maybe it's possible works.

nice~

Here's what I tried:

GPS connect
DevAnyKR/ESP32_8048S043C#2

I want to use Lovyan GFX, but I don't know how to use it with ST7262+LVGL9. I don't know C++ verywell. 😢

The ESP32-8048S043C is identical to the ESP32-4827S043C (except for the resolution) but there are several manufacturers, and not all use the ST7262. Some use the undocumented ILI 9485 chip and I believe there might be another.

This is a hard screen to get working - the documentation on the ST7262 specifies a minimum frequency of 23MHz for the 24 bit RGB (of which only 16 bits are wired) to the ESP32 with a 5 red, 6 green and 5 blue parallel configuration. However, if you operate at that frequency the screen loses VGA sync because the ESP cannot keep up meaning that the maximum frequency for a 16 bit RGB on this module is about 16MHz.
