Your posting must have been one of the most incoherent that we have ever
It sounds as if you are using an RC filter on a logic signal being sent
between the two PICs.
This is often more of a hinderance than a help.
Does the circuit work without it? If the circuit doesn't work right without
it, how does it go wrong?
If you have really made such a hash of your wiring that that you can't use a
direct logic connetion between two PIC processors, there are a lot of ways
in which you could set up a situation where an RC filter wouldn't help.
It is more difficult to set up a situation where a
logic-level-to-logic-level opto-isolator wouldn't help, but we've had junior
engineers with that sort of misplaced ingenuity.
Don't even think about trying to use an otpo-isolator with an open-collector
output - there a so many components for which you could choose the wrong
value, or the the wrong place, that your chances of success must be slight.
