/* Arduino Si4735 Library
* See the README file for author and licensing information. In case it's
* missing from your distribution, use the one here as the authoritative
* version: https://github.com/csdexter/Si4735/blob/master/README
*
* This library is for use with the SparkFun Si4735 Shield or Breakout Board.
* See the example sketches to learn how to use the library in your code.
*
* This file contains definitions that are only used by the Si4735 class and
* shouldn't be needed by most users.
