 *  BlankDecoderNMRAv1
 *  
 *  Based on the NmraDccAccessory_Decoder_1 example in the NMRA library examples.
 * 
 * Blank decoder that has switch statemnt set up for Accessory
 * Notice when the decoder is triggered mutliple calls are made to the decoder
 * This is not a fault, All codes are sent mutiple times very quickly
 * as if it was a loco it could be on a dirty bit of track


 Commands to send to DCC++ EX base station for testing
 <1>  = power on
 < a 25 0 > = accessory number 25 direction 0
 < a 25 1 > = accessory number 25 direction 1


 Pins used

 2 = interrupt pin for decoder messages/circuit
