Hello all,

I am working with graphic lcd CFAF240320K-T-TS and trying to implement the software demonstration software provide with it using AVR Atmega324p.

Currently I have:

1) IM3 + IM0 tied to GND to use the 16 bit interface mode, as indicated by CFAF240320K-T-TS datasheet

2) Using PORTA as lower byte(DB7-DB0),

PORTC as higher byte(B17-D10)

PORTD as control where, PD7= CD/RS PD6 =WR PD5=RD PD4=CS PD3=0 PD2=RES PD1= 0 PD0 = 0

3) am not sure what to do with X+,Y+,X-,Y-

Problem is, the lcd does not display anything after code is compiled and download with avrdude. Please help! any help is very much appreciated
