Welcome to the LCD Library for Arduino and Chipkit. It is a derivate of the original LiquidCrystal Library as sourced in the Arduino SDK. It has been developed to be compatible with the current LiquidCrystal library, its performance is almost 5 times faster and fully extendable if need be.
It supports most
Hitachi HD44780 based LCDs, or compatible, connected to any project using: 4, 8
wire parallel interface, I2C IO port expander (native I2C and bit bang) and Shift Register.
It currently supports 4 types of connections:
4 bit parallel LCD interface
8 bit parallel LCD interface
I2C IO bus expansion board with the PCF8574* I2C IO expander ASIC such as I2C LCD extra IO.
ShiftRegister adaptor board as described Shift Register project home or in the HW configuration described below, 2 and 3 wire configurations supported.
ShiftRegister 3 wire latch adaptor board as described ShiftRegister 3 Wire Home
Support for 1 wire shift register ShiftRegister 1 Wire
I2C bus expansion using general purpose IO lines.

The library has had the invaluable contribution of:
piccaso - Florian Fida - Flo, thanks for testing and improving the SR library, initial version of the 1 wire interface and speed improvements.
Perry - firstname.lastname@example.org, with his thoughtful contribution, speed improvements and development support for the SR2W library.
Adrian Piccioli, with his contribution to the i2c GPIO support.
