I know the back light works because if I set jumpers on LCD module to TEST and apply 5v the back light comes on and PARALLAX INC, etc is spelled outon the module. Rests jumpers to 2400 Baud rate and nothing with program I described in note. All examples for PIC Basic Pro use LCD modules designed for Hitachi 44780 controller or equivalent which I believe use parallel input. I thought for serial input this LCD controller would work. SO question does PBP software support serial input ?? Hope this makes sense .. getting to limit of my understanding ........ thanks for any input.
