If PIC_PROG completed without errors then the bits specified in your HEX file are in the target chip, and the programmer is probably working correctly. PIC_PROG performs two verify passes, one at each Vdd limit, so the chance that the PIC is not programmed as specified in the HEX file is very very small when the program reports no errors. > Also how do I set the frequency using the pic_prog.exe You don't. That is a function of your code and your circuit. The oscillator setup is specified in the configuration bits, and your circuit controls the rest. ****************************************************************** Embed Inc, Littleton Massachusetts, (978) 742-9014. #1 PIC consultant in 2004 program year. http://www.embedinc.com/products -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
