    How do I get my PIC to tell if an input is oscillating/toggling at about 3 Hertz or so?

    depending of what your pic do. You can use TIMER interrupt to calculate pulses/secondes on this pin. if your PIC only monitor this pin you can use PULSIN,COUNT commands.

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.
