Support for JC4827W543C (successor of Sunton 4827S043C)

[ohlolol]

Hi Folks,

i just got my new Display i think its a new revision of the 4827S043C.

details of the board in my other post:
HASwitchPlate/openHASP#713

Arduino_DataBus bus = new Arduino_ESP32QSPI( 45 / cs /, 47 / sck /, 21 / d0 /, 48 / d1 /, 40 / d2 /, 39 / d3 */);

would be nice

I am also waiting for support. This screens are essentially like a CYD and i want to use one set of libraries.
Unfortunately I was unable to understand the configuration parameters.

Board examples: https://github.com/profi-max/JC4827W543_4.3inch_ESP32S3_board

Hi,

I made a quick attempt, as I do not own this board, so this might also be a goog starting point for you..

The changes are in the branch nv3041a of https://github.com/rzeldent/esp32-smartdisplay and https://github.com/rzeldent/platformio-espressif32-sunton.

Maybe this works?

Hi @rzeldent , thanks.
I try build this version.

1. Wrong declared variables: NV3401A_ => NV3041A_
   

2. Class for other lvgl version?

Fixed these issues. Am/Was having some issues with PlatformIO handing and unable to compile locally....

The firmware is loaded, but the display is empty (although the backlight works). COM monitor - also empty and does not even show the DEBUG information.

Been trying to get any of the demos that board came with to function. Sigh...seemingly did everything in the PDF it came with, but the Arduino IDE still has sadly shown many errors when trying to compile anything. And yes, did put the lv_config.h into the main dir of the libraries dir. Is it necessary to copy paste that lv_config file from a specific demo folder to main Arduino lib folder when compiling a specific demo's .ino?

Thanks in advance for answering soon and posting any relevant links about how to use that board.
