The LCD interface is a hybrid affair consisting of driving some segments
directly (MSD one, minus sign, decimal point and colon) and a
clock/direction interface for the main count. The LCD module outputs a
45 Hz square wave to facilitate driving the direct segments.
To make a segment visible, this square wave is inverted and applied to
the segment line.
I hope to receive a working LCD module this week and do some more
investigation. I have what I think is a complete schematic, but
I don't understand all of it yet so I consider it still a work in
progress. What I have so far is on the github site above.
