I want to implement GFX with SPI protocol on the ILI9488 LCD. Since I didn't see clear references on how to do this, I'm working almost by trial and error + reading some references. Now I'm in a situation where a problem has arisen and when I debug the function hal.backPorchExited(); is not executed even though vsync is triggered. I'm working with Adfruit driver and it shows text colors, so the hardware and the driver have no problem but when I want to use them with TouchGFX I have nothing just backlight. And of course, I have also written the functions required for LCD and TouchGFX communication, which don't seem to have any problems, maybe they do, but I'm not sure! But the problem is that now we don't even get to the function related to sending data. 
, does anyone have any experience? I searched a lot but couldn't find a suitable reference, so I went through trial and error.
