LCDi2c Library

This is the home of the i2c character based LCD libraries

Background:
After looking at the display choices I decided I wanted to use a display that ran on the i2c buss. This takes up only two pins and is very fast. As there was no current library I decided to write one, and in turn am making it available to the Arduino community.
API Compliance:
I have also put together a recommended API for use when developing libraries for character based LCD displays.
The character based LCD API documentation can be found here.
Info on using keypads with the library can be found here.

Notes:
The libraries as installed include the extended functions of each display. To disable the extended functions comment the #define _LCDEXPANDED out of the library. This will keep the extended functions from being compiled in, and thus save on available memory.
Every effort has been made to keep the libraries slim on memory usage, and as fast as possible. They have been tested with 0013 and 0015 of the arduino compiler on my mac.
Participation:
There has been much discussion via the forums and e-mail with other Arduino users. I would like to thank Ran Talbott for his advise, and contributions to the library, as well as petersson49 for positing his code for the robot-electronics LCD03.
News:
Initial Library and API created by Dale Wentz
09-14-2009 Mario added support for using a standard HD44780 compatible LCD using the PCF8574 . The new library named “LiquidCrystal_I2C” and can be found here http://www.arduino.cc/playground/Code/LCDAPI
09-13-2010 Brian Brumfield Added support for the Matrix Orbital LK162-12 Display
22.08.2011 Added support for the ST7036 LCD controller driving LCDs such as the Newhaven - NHD‐C0220BiZ, it can be downloaded from https://bitbucket.org/fmalpartida/st7036-display-driver/downloads.
