This Parallax LCD is a bare-bones, back-lit serial module for simple display applications in a 4 line, 40 character mode! But it doesn't actually have bones. That'd be gross and creepy.


Description [Hide]

The Parallax Serial LCDs are very functional, low-cost liquid crystal displays that can be easily interfaced to and controlled by a microcontroller using an I/O pin. Code examples are included for the BASIC Stamp® and Propeller™ chip. 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 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.

Update: 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 dollars of parts.

Features:

  • Clear 2x16 character display
  • Turn backlighting on or off with a single command
  • Directly supports ASCII DEC characters 32-127
  • Eight user-definable custom characters
  • Move the cursor anywhere on the display with a single command
  • Baud mode selector and adjustable contrast on the back of the display

Application Ideas:

  • Professional-looking text user interface on any microcontroller application
  • Easy serial debugging without a PC
  • Real-time sensor data output on autonomous robot

Key Specifications:

  • Power requirements: +5 VDC, 10 mA (light off), 50 mA (light on)
  • Selectable asynchronous serial baud rates: 2400, 9600, 19200
