/****************************************************
 * APC220 config
 * A small arduino by Jens Dalsgaard Nielsen, AAU
 * Studentspace  @ Aalborg University
 * http://es.aau.dk/staff/jdn
 * 
 * Find this code at github.com/jdn-aau/div
 * 
 * This program is for setting frequency and baudrate on the
 * apc220 radio using an arduino.
 * 
 * I is not able to setup the advanced features like network ID etc
 * In that case you need the apc220 config program (windows)
 * 
 * HOW TO USE IT ...........................
 * 
 * Upload this program to your Arduino UNO
 * (not to be used with DUE and other non AVR architectures)
 * 
 * 1) Attach radio to dig pin 8-13:

 * Program will search for teh radio and if find you will get a menu
 * for programming and reading radio
