Interesting point.. mine only has the 6 digit (7-segment) display, but
I'm sure it's multiplexed (digit/segment)..
But, the mux rate is fairly high, compared to the "transition time" for
the segments. So maybe I can average over some (short) time...
What I want to do is see what the temperature dependence is. (prompted
by leaving the fob in the sun, and having the code rejected, presumably
because it was "slightly ahead")
