Ok, I think I understand the method to the madness, but...

One thing I don't understand and haven't been able to get any info about on the net is which pins on the PIC the GPIO pins are - are they the RA or the RB pins, and is the numbering the same?

My other question is... why is the oscilator not connected to pins 15 & 16? I though that since those were the "OSC" inputs on a PIC, that they were the only pins that you could attach a Xtal to. And to recap quickly, it's supposed to be running @ 4.000Mhz, right?

Thanks again,

James.
