If the correct signals are reaching the display, then it has to be a display issue. I suspect the issue is with the micro, not the display. Try making the simplest routine you can to use the display, and if it still doesn't work, post it here. Someone will probably be able to pic the problem out for you. -Adam TOM THERON wrote: > > Hi everyone > > I have a LCD (8 x 1 line) routine, that works fine with my PIC16C63-04.
