  7.     This library is designed to use CC1101/CC1100 module on Arduino platform.
  8.     CC1101/CC1100 module is an useful wireless module.Using the functions of the
  9.     library, you can easily send and receive data by the CC1101/CC1100 module.
  10.     Just have fun!
  11.     For the details, please refer to the datasheet of CC1100/CC1101.
