/*************************************************************************
|
||
|
|
* 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)
|
||
|
|
