 Most displays in this category (16 chars/1 line to 40 chars/4 line, ) use
the Hitachi HD44780 chip, and so program up the same. They even have the
same 14 pin interface (15 for the 40/4 which has 2 chips and so 2 enables).
So take you pick regarding size, backlighting, price etc. The interface is
8 bit parallel (with a 4 bit mode possible - handy if you have only one 8 bit
port), with a R/W line, Register select, Enable line, Power, Ground and Contrast
You'll need a micro to do the serial to parallel for you: If you use an
8051, drop me a line and I'll post you the software I wrote for one of these
things.
