Hi Scott,

Does the programmer verify what was programmed into the chip?

What clock source are you using for the PIC, RC, crystal, resonator ??

Is the OSC FUSE set accordingly?

For example, if you have a 4MHz crystal with 2 18p caps, then use HS
mode.

Is MCLR tied to 5V?

Is the WDT disabled?

In the PIC circuit, are there series resistors with each LED and IO pin?

Best regards

Tony
