That works, so it must be the crystal. I've used these crystals with my 18f2620 and they've worked fine. I'll get the proper crystals. Do you have any part recommendations?

Thanks again!

1. The pic is running +5 volts from a computer's usb.

2. The 47k resistor on masterclear goes to 5v.

3. I'm using this crystal on pins 11 & 12:

The version is 4.088. This is not a proteus project. I'm just using a breadboard.

Weird. I tried this simpler program and now the light doesn't blink. I tested different timings to be sure that I wasn't missing it. Other ideas?

Thanks. I've changed the fuse. (I had it this way earlier and thought it might be the problem):

#FUSES HS

I also commented out the second #use delay. The light still blinks about 50 times too ...

This is a problem that I've encountered before, but I've never solved it. My pic chip is running about 50 times too slow. I'm trying to blink an led 100 times a second, but it blinks about 2.7 times ...

I've added the capacitors to both of the chips running this code, and that has solved the booting problem. However, one now has serious timing problems. It is running about 20 times too slow. Any i ...

Thanks for the advice. I commented out the interrupts, and the problem still happens, so I think it must be in the board.

I designed the board, and had it fabricated by pcbfabexpress. I've taken ...

When I don't have serial plugged into my board, my pic chip boots great everytime. When I do have serial plugged in, the chip boots correctly about 2/3 of the time. If I plug the serial in after boo ...
