Librería LiquidCrystal

This library allows an Arduino board to control LiquidCrystal displays (LCDs) based on the Hitachi HD44780 (or a compatible) chipset, which is found on most text-based LCDs. The library works with in either 4- or 8-bit mode (i.e. using 4 or 8 data lines in addition to the rs, enable, and, optionally, the rw control lines).

Esta biblioteca permite a la placa Arduino controlar displays LCD basados en el chipset Hitachi HD44780 (o compatibles), que se encuentra en la mayoría de LCDs de texto. La biblioteca trabaja en modo 4-bit o en 8-bit (es decir, por medio de 4 u 8 líneas de datos, además de RS, ENABLE, y, opcionalmente, las líneas de control RW).

• print()

• clear() - clears the display
• home() - sets the cursor to top left
• noDisplay() - blanks the display but saves the data onscreen
• display() - restores the screen after noDisplay()
• noBlink() - turns off the block-style cursor
• blink() - turns on the block-style cursor
• noCursor() - turns off the underscore-style cursor
• cursor() - turns on the underscore-style cursor
• scrollDisplayLeft() - scrolls the whole display left
• scrollDisplayRight() - scrolls the whole display right
• shiftLeft() - sets direction of text flow to left
• shiftRight() - sets direction of text flow to right
• shiftIncrement() - "left justifies" the text
• shiftDecrement() - "right justifies" the text

NOTE: The LiquidCrystal library has undergone revisions after Arduino version 0016. Thanks to Limor Fried for the rewrite to include 4-bit and 8-bit modes and more functionality.

The documentation re-write is still in progress. In the meantime, enjoy these tutorials showing how to use the library.

If you are running Arduino 0016 or earlier, please download the current version of the LiquidCrystal library and install it in your hardware/libraries folder.
