Microcontroller › PIC › PIC18F4550
How to interface LCD with PIC18F4550 Microcontroller is a very good tutorial.
I try it in Proteus 8.1 and works fine. But, when I build protoboard
with LCD JHD162A and PIC18F4550 doesn't works. What can go wrong?
does you connect potentiometer with LCD for contrast purpose?
