Currently the following boards are supported by the library:
* All official Arduino AVR boards (Uno, Duemilanove, Mega, Mega 2560, Mega ADK, Leonardo etc.)
* Teensy (Teensy++ 1.0, Teensy 2.0, Teensy++ 2.0, and Teensy 3.0)
* Note if you are using the Teensy 3.0 you should download this SPI library as well: <https://github.com/xxxajk/spi4teensy3>. You should then add ```#include <spi4teensy3.h>``` to your .ino file.
* If you are using the Arduino Due, then you must include the Arduino SPI library like so: ```#include <SPI.h>``` in your .ino file.

* Teensy (Teensy++ 1.0, Teensy 2.0, Teensy++ 2.0, and Teensy 3.x)
