    ds,
    Do your switch readings need to be checked often, rearly, only once ?

    they will either be polled at the top of the main loop or in response to a button push, haven't started the program yet

    it looks like i will be using the 7 pin diode matrix approach after all since it seems to offer the best set of tradeoffs given other considerations in the design, i just really don't like stuffing the 12 diodes due to insertion cost
    oh well
