Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

I am having trouble finding 8 consecutive pins for a 8 bit port .
Should I be looking at the P numbers on the attached ?
There seems ( and my brain is burnt    ) that there is a ground
pin interrupting any 8 consecutive pins ?

Why do you think consecutive is good or required? Quazee's new PCB design shows the allocation of the pins very clearly: Expansion Pinout

All of the pins don't have to be consecutive. Use the pin numbers as shown on page 10 of the manual. EG:

PORT(2,4,7,2,10,2)

IE: pins 2,3,4,5,7,8,10 and 11

Translate to
