Ok, I got around to trying the example in this thread. I had to change a piece or two because I'm using a PIC12F683. The main changes were to change TRISB to use TRISIO (since there is only one GPx PORT), and of course the SHIFTOUT command to use the correct pins on that port as well.

I'm getting no results, and it doesn't seem that the CCP module is working correctly. Is there a way I can test this individually?
