Features and Overview

  • Uses the industry standard Hitachi HD44780 LCD display driver chip protocol
  • Requires only seven I/O pins
  • Routines provided to print RAM or ROM strings
  • Routines provided to print numbers
  • Routines provided to display horizontal and vertical bar graphs
  • Uses a single I/O port
     

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 works for many other fourline displays. This library uses the 4-bit interface mode to limit the number of I/O pins required.
