Please explain how serial access to an LCD reduces the code size compared to
full parallel access? I know it reduces the number of pins (though I would
go for a three pin interface with a normal shift register, and not Myke's
two pin interface... I never had much luck with that) but in my experience,
it increases the code size: instead of a simple "move data to port, toggle
enable" you now have to shift each bit separately and then toggle enable.

In Brent's case it doesn't really help either, as it would still result in a
redesign of his PCB, which is the thing he is trying to avoid.

I do appreciate seeing the old example from Myke Predko coming back, though
(I liked his book a lot).

Maarten Hofman.
