I have been lurking for a long time now and I finally bought a PICit 2 and am excited to get past the first step...flash a LED. I decided to use a 16F628A partly because I did not have the parts available to add a clock (I am looking for a good place to buy low quantity ceramic resonators hopefully with the caps built in). I used the 'simple' sample program changing only the processor type. I put the chip on a solderless bread board and ran power to pins 5 and 14 I also ran a wire from pin 8 to one side of an LED and from the other side back to the power rail. I was able to program the chip successfully (the PICit recognized the chip, uploaded the program, and verified it.) but the LED does not light (on the bb, the ones on the PICkit work just fine). I tried switching the wires going to the LED in case I have the polarity wrong (unfortunately I removed this from an old CDROM and there is no flat side or longer lead) I know it works though since I can quickly put it to the power supply and it lights (This would tell me the polarity if I had thought to pay attention). I also tried switching which rail I take the other side of the LED to (positive or negative)..and then swapping the wires to the LED again. All to no avail. Now for where I imagine the problem is coming in (let me know what you think). 1) I have not tied any of the other pins to anything. Can I tie them all (selected pins?) to a resister and then that to the negative rail or do I need enough resistors for every unused pin? 2) The power supply is an old Motorola cell phone wall wart charger. It gives me about 4.6V @ up to 1.5 A but I have not put any caps anywhere. I have read the FAQ's and searched online but am not sure where to head next.
