I have a pic (16f876) hooked to another pic (16f876) using a single wire. If
PicAPortC grounds the line, PicBPortB will start a program. This connecting
line is only 12 inches long and the fastest this line may turn on and off
would be roughly every 3 seconds. Can I use just a 470k pull-up resistor on
PicB? Will I need to put a resistor in series and/or a .1 cap (between line
and +5volts) so PicB would not get zapped? The fastest this line may turn on
and off would be roughly every 3 seconds.
Thanks Wrong Way Ray (Raymond Choat)
