Hello,
I am trying to interface graphic LCD 240x128 (part: T240128 v1.1) with PIC16F877A. I used MicroC compiler's example coding & also simulated on proteus. On Proteus simulation, LCD worked alright, but when i set up the hardware, LCD is showing only a bar of line (Sometimes on top, or middle or bottom (after resetting)). I have adjusted the "V0" (contrast) to -15V, & have checked all the grounds & VCCs. And have set configuration byte as = 7FA3. I tested the PIC16F877A by LED Blinking Program. I also have attached the project, code, hex (Note: coding done in MikroC Compiler).
Please, Help me, what could be the problem?
