The Character LCD User Module is a set of library routines that writes text strings and formatted numbers to a common two- or four-line LCD module. Vertical and horizontal bar graphs are supported, using the character graphics feature of these LCD modules. This module was developed specifically for the industry standard Hitachi HD44780 two-line by 16 character LCD display driver chip, but will work for many other four-line displays. This library uses the 4-bit interface mode to limit the number of I/O pins required.
