In CTE's version of Henning's library you can initialise the library using the command:
//UTFT myGLCD(model);
UTFT myGLCD(CTE70);
Which is basically telling it that you are using a 7" TFT screen on a CTE shield.
With Henning's original library you have to specify the pins used for the control lines so.
//UTFT(model,RS,WR,CS,RST{,SER}); where SER is optional
UTFT(SSD1963_800,25,26,27,28);
But nothing happens. I got the control line numbers:
25 for RS
26 for WR
27 for CS
28 for RST
from CTE's circuit diagram for their shield comparing it against the DUE/MEGA's digital pin numbers.
