UTFT library not working with Due

I am trying to use the UTFT library given on the henningkarlsen page but it is not working with my Arduino Due. The link for library is
http://henningkarlsen.com/electronics/library.php?id=52
When i am using the same library with mega it works with the same code..... Also with Due i am successful in uploading the code but nothing turns up on the screen

Are you using an adapter board ? where the LCD plugs into the adapter and the adapter plugs into the Mega / Due ?

If so, that is the reason it will work on the Mega but not the Due.... the Mega is 5v... to the adapter board has resistors on it (100 ohm) to bring the voltage down.... the Due is 3.3v.... so if you use the adapter board, those resistors bring the 3.3v down... to a voltage too low to send signals to the LCD

Wire the Due up directly and it will work.
