What about the config bits.....are you sure that you have the oscillator set to the correct type? I'd have to go back and read your post again, but the FIRST thing I check if it appears to be non-working is check the power and ground (I think you did that) and then if its an RC or XTAL oscillator (such that the osc/4 pin is not tied to anything) look for the clock coming out that pin. All you need to do is code a little delay loop and flash the LED. I do that almost every time I do a project so that I can immidiatly see if the code is loaded and running. Not only do I do this on micro's but also for FPGA's. _________________________________________________________________ Enjoy MSN 8 patented spam control and more with MSN 8 Dial-up Internet Service.
