SparkSoftLCD : An Arduino Interface to the Sparkfun Serial LCD
This software is released as open-source under the GPL License version 2.1
SparkSoftLCD is a library that provides all necessary methods to use your Sparkfun Serial-Enabled LCD easily. It is based on the SoftwareSerial library provided with the Arduino core, by David Mellis. This version removes unnecessary functions to save memory, and adds extra methods to access the core functionality of the LCD with a minimum amount of effort.
This library does not require any Serial module to be loaded (including Software or Hardware serial variants), and lets you use any Arduino pin for communicating with the LCD.
