Edit, ok I think I have a "debounce" strategy, for dealing with this. I have to change it so it looks for X number of milliseconds in a given state before deciding to increment the vss pulse counter. Only tricky bit is the timing of the pulses should be done on the leading edge, and not whenever the pulse settles down. I think it is doable with the event scheduler though, instead of just disabling the pin interrupt for a given amount of time I will schedule an "increment the counter" event that will get overridden with each junk pulse.
