Hi all. I'm using a 16F877 with an LCD connected through a 4-bit bus to the upper 4 pins of port A.

I have made a PCB for this circuit and only just realised that the ports I have chosen for the LCD might be a problem. Port A only has 6 bits, so I would need to define the LCD starting port as a.2, but PBP only allows you do define it as port 0 or 4. Is there any way around this without using assembly to write my own LCD routine?

Thanks again.

Matthew

Not in PBP... change your circuit or write your own LCD routines.
