    WooHoo! Somebody's paying attention.

    Hi Mike,

    That's a VERY interesting idea!
    Not sure at this point how I can let the user assign the pins at random, in any order, and any number of them, on any chip. But this sounds good enough to see if I can find a way.

    For combining the smallest periods ... I already add the lsb from each side of the "mirror" into a single period to double the minimum interrupt time. Not sure where your 3rd one comes from. That would make the lsb worth 1.5.

    I had also tried combining the 2 lsb's on both sides, but that reduced the resolution to 7-bit instead of 8, so the results weren't very good.

    I'll see what I can do with the "Full PORT Press".

    Thanks for the great idea.

    Add: Hmmm, that would help minimze R-M-W issues too.
