Just a quick question. I need to use channel 13 on the 16F689 as a comparative reference. What do I use for setting up the port when calling:
setup_adc_ports(sAN0 | VSS_VDD);

Thanks PCM. That makes sense now. I've got the code space to add it in, so I'll give it a shot. If I have any questions I'll hollar. It would be a lot easier if the user would just RTFM! Reading ...

Just want to make sure that my thinking is correct that once the clock and data lines are defined there is no way to swap them. Our product depends on the user to make contact with the correct orient ...
