hi i am trying to work on an lcd. I' m using avr studio 4. i have attached lcd.h and lcd.c in my project from peter fluffy. it displays a simple text in proteus. i connected the circuit accordingly. i burnt it in my atmega32. but it doesn't show text. when i connect the usbasp programmers ground with the ground of mcu, it works and displays the text. when i remove programmers ground, the text is gone. this is like a problem to me( don't mind, no offense).
i'm very much tired . can't get any solution . please help
