Hi all
I`ve just migrated a program over from a 16F648A to a 16F877 and it now refuses to serial in on porta.0. I`m sure this has to be a register not set, I know on the 648A is CMCON=7 for all digital on port A but for the life of me I cant find the relevent info for this device. Does anyone know this offhand?
Cheers Pete
Do you have
ADCON1 = 7
someplace in your code. ( I think that is correct for your chip, might be ANSEL )
Hi Dave
I think its still cmcon = 7 which I`m sure is wrong, I`ll try ACCON1 = 1 and see. Its certainly that because the setup works if I apply the serial to portb and recode.

What I was getting at is the 877A has analog also.

Hi Dave
Thanks ADCON1 did it, I had a feeling it was coming up in Analog mode I just couldnt find the correct register to set.
Many thanks, Pete
