Yes that nv3030 is so damn difficult to get going I just gave up. I did look at the wiki, downloaded those files but it seams marrying it up with an S3 is impossible. With the smaller 7789 display, I did notice when I tried 5v supply to the display it stopped working and on 3.3v it worked so that does make a difference. Now trying to get the camera to work and display on the screen is another headache!
