I don't understand how you expect things to work if you add a random capacitor? A 22pF capacitor can, except for the markings, look identical to a 100nF cap. Put a resistor in the MCLR line, and in the LVP line. Connecting such pins directly to ground or power is bad karma. OK now that you gave an approximate circuit diagram, what code is in the chip? Read it from the chip, and give the resulting .hex file. The one read from the chip, not the one you put into it. -- Wouter van Ooijen -- ------------------------------------------- Van Ooijen Technische Informatica: www.voti.nl consultancy, development, PICmicro products docent Hogeschool van Utrecht: www.voti.nl/hvu -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
