> Selected OSC to XT for ceramic resonator, F84 chip and LPT1. This is irrelevant when trying to program the chip. The crystal oscilator doesn't start up until the chips programmmed anyway so this is a red herring. You don't need any crystal to program it. > Clicked the > burn button and received following error message > "Failed at 0x0: Expecting 0x3000, found 0x3FFF." This is indicating a fault with the hardware, probably just timing or something silly like power suppliers. Check you have power to the chip and that you have the correct power supply for the programmer. Remember you need a 13V supply on MCLR for programming and thus your power supply input must be at least 13V or more. Check the details of your hardware. > What did I do wrong?

It doesn't. Sorry but I use the P16PRO programmer and haven't experience using anything else. Regards Pete -- http://www.piclist.com#nomail Going offline?
