ADDAC_Ntof.h

/*
 * ADDAC_Ntof
 * 
 * Developer's blank page Class example
 *
 * in Arduino environment simply add at the very top:
 
 #include <ADDAC_Ntof.h> // This loads the Class when compiling
 ADDAC_Ntof Empty; // This Instantiates 1 Class with the name "Empty"
 
 *
 *
 * then in BEHAVIOUR() add at a position of your choice:
 
 unsigned int CV = Empty.update(random(0, 65535));
 
 or if you want to write it straight out at channel 1 for ex.:
 VCC.WriteChannel(1, Empty.update(random(0, 65535)) );
 
 *
 *
 * or to simply get the current value back use:
