Hi again,

Its not my first program but its just i never used multiple files or drivers thats all.
I tried all what i said and its working fine on Proteus but when i connect it in real, the LCD is displaying nothing. I used 20Mhz xtal as its the only available. Now does it have anything to do with that.
Sorry for bothering but i really wanna it to work :(

First get rid of Proteus as it does NOT simulate the real world, as you've found out !

Second, have you got a simple 1Hz blinking LED program to run ? This would confirm correct hardware as well as basic programming.

Third, use the flex_LCD driver as pointed out it works fine and should run the LCD you have.

4th, post your complete test program and a schematic of what your hardware really is. The more info the better we can diagnose what could be wrong.
