parallax lcd display for sale

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.

Custom characters and other features are available for this LCD. When developing your sketch, print things to the LCD screen only once if they do not change. For example, the text in this sketch is printed once in setup(), while the variables are printed repeatedly in loop(). void setup() { Serial.begin(9600); // use a baud rate of 9600 bps pinMode(1,OUTPUT); // set pin1 as an output (pin1=TX) Serial.write(12); // clear screen & move to top left position Serial.write(131); // move cursor to row 0, position 3 Serial.write("Louisiana Tech"); // print a text string starting at (0,3) Serial.write(153); // move cursor to row 1, position 5 Serial.write("University"); // print a text string starting at (1,5) Serial.write(190); // move cursor to row 3, position 2 Serial.write("i= x="); // print text string at (3,2) Serial.write(22); // turn cursor off to keep screen clean } void loop() { float x=0.0; for (int i=1;i<=10;i++) { x=x ; // add to variable x Serial.write(192); // move cursor to row 3, position 4 Serial.print(i); // print i at the current cursor position Serial.write(" "); // print blanks to cover previous printing Serial.write(200); // move cursor to row 3, position 12 Serial.print(x,4); // print x to 4 decimal places delay(1000); // delay 1 second between printing numbers

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® 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.This device can be connected to a PC serial port using a MAX232 line driver.
