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. The LCD 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 visible ASCII characters Dec 32-127, and in addition you may define up
to eight of your own custom characters to display anywhere on the LCD.
NOTE: If your Serial LCD Display does not have a speaker on the back, use the specifications
and information in the Product Change Notice: Revision E and Earlier section on page 11.
