/*************************************************************************
|

* This demo does high speed testing of the Serial1 hardware port. On |
||||
* The TGA Pro, this is used for MIDI. MIDI is essentially a Serial protocol |
||||
* running 31250 baud with port configuration 8N1. |
||||
*
|
||||
* Despite there being MIDI physical circuitry on the TGA Pro, we can still |
||||
* run a serial protocol at different rates to ensure a robust design. |
||||
*
|
||||
* CONNECT A MIDI CABLE FROM MIDI_INPUT TO MIDI_OUTPUT AS A LOOPBACK. |
