This library was originally copyright of Michael at elechouse.com but permision was
granted by Wilson Shen on 2016-10-23 for me (Simon Monk) to uodate the code for Arduino 1.0+
and release the code on github under the MIT license.

To: Simon Monk <[email protected]>
Thanks for your email.
You are free to put it in github and to do and change.

Hi,
I'm Simon Monk, I'm currently writing the Electronics Cookbook for O'Reilly. I use your
ELECHOUSE_CC1101 library in a 'recipe'. Your library is by far the easiest to use of
the libraries for this device, but the .h and .cpp file both reference WProgram.h which
as replaced by Arduino.h in Arduino 1.0.
Rather than have to talk my readers through applying a fix to your library, I'd like
your permission to put the modified lib into Github and add an example from the book.
I would of course provide a link to your website in the book and mention that you can buy
the modules there. If its ok, I'd give the code an MIT OS license, to clarify its use.
Thanks for a great library,
Kind Regards,
Simon Monk.
