    Default Re: 2 LEDs used Bi-directionally

    I feel like a retard. So...

    PIN --- DUAL LEDs --- RESISTOR --- 5VDC

    PIN defined as output:

    HIGH will source, turn on outgoing LED (like we always do)
    LOW will sink, turn on incoming LED


    I don't get how I'm to set ports/TRIS at both ends so neither LED will turn on. I've gone through that thread and a few others all evening but I can't see the forest through the trees apparently.

    Even if my ports are defined as digital?
