Hi all, I am using C18 complier to program PIC18F452 microcontroller to display data on a LCD display module (Hyundai Korea - HB16202-A). The microcontroller is connected with an external oscillator SG531P, and giving it a frequency of 40MHz. The problem that i encounter is that, i am not able to display any information or character. I wonder whether is it the oscillator thats causing ...
