Hello, I have a v.3 development board and I'm using PIC16F88 chip. For some reason, I just simply can't use port RA5-RA7. They somehow always act as if they are inputs but they don't really do anything. Even if I set the port direction to output, they still wouldn't output anything; in fact, they st...

Yes I do. Here's what's written in the err file. Thanks.

I am able to compile the following C-code but keep getting error during the assembly process. What I am trying to do is to run the comparator in mode 011 (two common voltage reference) and generate output based on the comparator out. Thank you in advance. Main Program: // Comparator function try-out...
