/*************************************************************************
|
||||||
|
* This demo uses only the built-in libraries provided with the Arudino |
||||||
|
* Teensy libraries.
|
||||||
|
*
|
||||||
|
* IT IS STRONGLY RECOMMENDED to use the BAGuitar Library located at |
||||||
|
* https://github.com/Blackaddr/BAGuitar
|
||||||
|
* The BAGuitar 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 BAGuitar library |
||||||
|
*
|
||||||
|
* For instructions on installing additional libraries follow the |
||||||
|
* instructions at https://www.arduino.cc/en/Guide/Libraries after downloading
|
||||||
|
* the BAGuitar repo from github as a zip file. |
