/*************************************************************************
|
||||
* This demo uses only the built-in libraries provided with the Arudino |
||||
* Teensy libraries.
|
||||
*
|
||||
* IT IS STRONGLY RECOMMENDED to use the BALibrary Library located at |
||||
* https://github.com/Blackaddr/BALibrary
|
||||
* The BALibrary library will made it easier to use the features of your |
||||
* GTA Pro board, as well and configure it correctly to eliminate |
||||
* unneccesary noise. |
||||
*
|
||||
* The built-in support for the WM8731 codec in the Teensy Library is very |
||||
* limited. Without proper configuration, the codec will produce a noisy |
||||
* output. This is caused by the default configuration the WM8731 powers |
||||
* up in. This can easily be corrected by installing the BALibrary library |
||||
*
|
||||
* For instructions on installing additional libraries follow the |
||||
* instructions at https://www.arduino.cc/en/Guide/Libraries after downloading
|
||||
* the BALibrary repo from github as a zip file. |

If you've never used the the library examples before, start with the "Basic" ones. |

Pick the correct one based on how many SPI SRAMs you have. (0, 1 or 2 SRAMs). |

Use BAExpansionCalibrate to test our the Blackaddr Audio Expanson Control Board if |

you purchased one. |
