    Default Re: LED Matrix display

    BTW, feel free to tell me if you think I'm nuts.



    You can turn either LED on, or both LEDs off with combination of toggling TRIS for the pin, and the value on the pin.
    You just can't turn both of them on at the same time, because the pin can't source and sink current at the same time.
    We can fail to source or sink current to achieve the state of both LEDs off.

    A matrix display only has to light a line at a time.
    Why can't that be extended out to an entire matrix display?
