After banging on this thing for a few hours I'm beginning to think this device is really chewing gum with metal legs. This is kindof' an odd device; its like a "PIC12Fxxx" but with a "PIC16Fxxx" designation, with built-in opamps (which is why I'm using it).

I'm simply trying to blink an LED. The outputs, across the board, seem to be set as inputs. The first question I have is, how does one set the TRISA on 12 bit devices? If I give it a TRISA command I get an error. Data sheet isn't much help; it refers to "TRISA, TRISB, TRISC". Despite that, I don't think that's the problem given that my LED is on PORTC.0...

As you can see in the code, PORTC.0 is an output, and I believe all the appropriate configuration bits are set properly. Comparators are off, A/D is off, OPAMPS are "on", ANSEL is configured. I know the part is running; I can see the clock out on the clock out pin (DIV/4). MCLR works as well. Just no output from anything. Can someone give this an eyeball and tell me what I've over-looked? Never had so much trouble with any device blinking an led...

BTW: I'm using the latest PBPX 3.0.7.4 with a U2 programmer running meProg v.4.51.

Thanks in advance,

Mike T.
