I got a problem with the 3.2" TFT. I connect the TFT module with Arduino MEGA 2560. Then I followed the instruction from http://forum.arduino.cc/index.php?topic=101029.0, downloaded UTFT library, used UTFT_demo 320x240 and changed the display model to SSD1289. It can show the demo, but with many thin white lines. The lines moves when the image moves.
I have checked the wiring and it still happens. Any one knows why is that? Thanks for the help.
