Big thanks to members hooked up and to bliptronics for help working out the input from my iphone.
/* Code to read the Spectrum Analyzer chip from bliptronics.com
* http://www.bliptronics.com/item.aspx?ItemID=116
*
* Important: Connect a wire from the 3.3v to the ahref on the shield to work with netduino.
*
* * Based on code from bliptronics.com and arduino community assistance.
* Port by: Joseph Francis
