Graphical LCD programming

Hello guys,
I have to program a custom made 38X60 graphical LCD using a SITRONIX driver.
I have no idea where to start.
Any suggestions on tutorials or reference programs.
I am using ccs compiler for PIC18F4550.

I have programmed alpahnumeric LCD's (2X16) but have no idea about graphical LCD's.

Thanks

Hi, ,
you can get good source code and info at www.microchipc.com

you might have got a datasheet along with your custom LCD? didnt you?
