/* this code is here to test the waveforwe generator and reveal the issues involved in programming track operations.
*
* It tests the Waveform genartor and demonstrates how a DCC API function can be simply written
* to transmit and receive DCC data on the programming track.
*
* Important... DCCWaveform.h contains hardware specific confioguration settings
* that you will need to check.
*
* Notes: the waveform generator sends reset packets on progTrack when it has nothing better to do, this means that
* the decoder does not step out of service mode. (The main track sends idles).
* It also means that the API functions dont have to mess with reset packets.
