> A pulldown resistor will hold that pin low, during the interval > before the processor gets started I seem to be out-suggested pull-down vs pull-up 3:1, but if the resistor is a pulldown and the LED is Vcc to pin, surely the blip will still occur ? It will come on at power-up and go off only when the pin is driven high -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
