The Parallax Serial LCDs (liquid crystal displays) can be easily connected to and controlled by a microcontroller using a simple serial protocol sent from a single 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). In addition, you may define up to eight of your own custom characters to display anywhere on the LCD. An onboard piezospeaker provides audible output, with full control over tone note, scale and duration using ASCII characters Dec 208–232.
The LCDs currently for sale are updated to Revision F. Basic functionality remains the same, but power requirements and the layout of the backpack have changed. Please see the documentation for information on your model.
This device can be connected to a PC serial port using a MAX232 line driver. The circuit isn’t supported by Parallax, but it’s possible to make this connection with a few extra parts.
