ELECHOUSE_CC1101.cpp - CC1101 module library
Copyright (c) 2010 Michael.
Author: Michael, <www.elechouse.com>
Version: November 12, 2010
This library is designed to use CC1101/CC1100 module on Arduino platform.
CC1101/CC1100 module is an useful wireless module.Using the functions of the
library, you can easily send and receive data by the CC1101/CC1100 module.
Just have fun!
For the details, please refer to the datasheet of CC1100/CC1101.
