I was wondering a couple things about this SX/B example as well.   I happen to have a bunch of common anode displays, but those look like they will hook up to the example well with inverting the data output logic and maybe putting a transistor on the common anodes so that shouldn't be a problem.   The part I'm not so sure of is this:


1) What's the maximum # of 7-segment displays that can be multiplexed without excessive flickering or dimness?

2) If I want a 4-6 digit LED display that accepts serial data, can I just use an interrupt and still have things be reliable?
