I have an ILI9488 3.5in TFT LCD from eBay. I found the code to get it working, sorted out the touchscreen coordinates and other stuff. Now I’m trying to figure out why it fills rectangles weird. They have diagonal miscoloured lines smeared across them? But I can draw text absolutely perfect, so I doubt the LCD is defective. Are some pins mismatched or something? Can anyone point me in the right direction?
