Good evening,
I have recently bought a el-cheapo (mcufriend) 2,8 inch tft touch screen on ebay.
After a couple of hours of reading and trying (and some cursing too 
) I finaly got the LCD a bit working.
Im using the ST7783 library as posted in this topic and I got some images on the screen.
But the problem is that there are a couple of white/rainbow lines on the left side of the screen.
The other problem is that when I use the tftpaint demo and I draw a line from left to right, the lcd is painting from right to left. So the screen is mirrored I gues.
Anyone have ideas to fix this problem, because Im out of options.
Thanks in advance!
Regards,
Theo
