Introduction
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 Regiter.
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.
How do I get set up?
- Please refer to the project's wiki
Contributors
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.
- B. Perry - bperrybap@opensource.billsworld.billandterrie.com, with his thoughtful contribution, speed improvements and development support for the SR2W library.
- Adrian Piccioli, with his contribution to the i2c GPIO support.
- todbot Tod E. Kurt for the softwarei2cmaster library.
- felias-fogg - Bernhard for the softwarei2cmaster fast
