+ 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.
