/*************************************************************************
 * This demo uses the BALibrary library to provide enhanced control of
 * the TGA Pro board.
 * 
 * The latest copy of the BA Guitar library can be obtained from
 * https://github.com/Blackaddr/BALibrary
 * 
 * This demo provides a very simple pass-through, clean audio example. 
 * This can be used to double checking everything is hooked up and working correctly.
 *
 * This example also demonstrates the bare minimum code necessary to pass audio
 * through the TGA Pro:
 *     - BAAudioControlWM8731 to enable and control the CODEC
 *     - AudioInputI2S to receive input audio from the CODEC (it's ADC)
 *     - AudioOutputI2S to send output audio to the CODEC (it's DAC)
 *
