A parallel display can take up too many pins for the application.
Most serial display are much more expensive.
A good compromise is to use the PH Anderail serial driver kit for
LCD's. These kits start at $5 and included a dedicated PIC acting as
a serial to parallel LCD controller.
The PIC takes care of all the overhead and has a built in command
structure for display commands and works great!
These guys
http://www.wulfden.org/k107/index.shtml have just
introduced a pcb to go along with PH Anderson's kit. It worth taking
a look at.
