I seen many advertisements for serial LCD's in magazines like
Circuit Cellar etc, and presume these are just ordinary parallel
LCD's with a dedicated microcontroller like a PIC to turn it into a serial
device. This looks like quite a good idea, especially in
applications like my current one where free I/O pins and code space
are rather restricted. However, I'm not quite sure if these serial
LCD's can do everything that I want to do with it. Do anybody know
where I can get hold of a datasheet on one of these serial LCD
devices? Better yet.... is there perhaps someone out there that
has implemented such a serial LCD driver in C and is willing to make
that source code available to me?

I believe that there was a full description, including code, for Scott
Edwards' "serial backpack LCD display" (one of the first such devices)
published in Nuts&Volts. Try their web page. (I don't think it was
written in C, though!)

Werner,
If I remember rightly, Todd Peterson (E-Lab Engineering) and Noguiera
both sell PICs that will do what you want, but no source code.
