The Parallax Serial LCDs are very functional, low-cost liquid
crystal displays that can be easily interfaced to and controlled
by a microcontroller using a I/O pin. Code examples are
included for the BASIC Stamp
displays provide basic text wrapping so that your text looks
correct on the display. Full control over all of their advanced
LCD features allows you to move the cursor anywhere on the
display with a single instruction and turn the display on and off
in any configuration. They support the same visible characters
as the BASIC Stamp Editor's Debug Terminal (ASCII Dec 32-
127). In addition, you may define up to eight of your own
custom characters to display anywhere on the LCD.
