Add support for Waveshare ESP32-S3-Touch-LCD-4

[gavzzorz]

i see you have support for the 7" version that is similar so should be a quick add.

i tried adding a board conf for it but i might have missed something as i just have a black screen where previously i got a display with the same project with board ESP32-2432S032C.

Thanks for a great project that really helps with these ESP32 Displays :)

I got my LVGL project to work on the ESP32-S3-Touch-LCD-4.3B device. I just copied the Touch-LCD-7 JSON file and modified the extra_flags to match the pins and values for the 4.3" version (based on the values from the esp_panel_board_custom_conf.h file in the 09_lvgl_Porting Arduino example from the demo files). I'm still trying to work out issues with screen jitter and such, which is probably due to needing double buffering or something

Nice, if you found the right pins/plclk I can put it into the definitions so it will work out of the box!

@xBurningGiraffe I should have linked it, but I made a conversation im here too. I got the touch driver working last night so its all working but it really needs ironed out still! Colors are wrong and the touch driver isnt fully implemented nicely, its a modified version of one of the already existing drivers with a modified read function based on what I saw in the example files

@gopro2027 What do you mean specifically by "the colors are wrong"

[gopro2027]

@xBurningGiraffe They are inverted. FF0000 shows 00FFFF.

@gopro2027 Could you link your modified versions of the files you're using?

[gopro2027]

you're
