/*************************************************************************
|
||
|
|
* This demo uses the BAGuitar 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/BAGuitar
|
||
|
|
*
|
||
|
|
* This demo demonstrates how to override the default AudioEffectDelayExternal
|
||
|
|
* in the Teensy Library with the one in the BAGuitar library. This is necessary
|
||
|
|
* because the SPI pins in AudioEffectDelayExternal are hard-coded and not the
|
||
|
|
* same at the TGA Pro.
|
||
|
|
*
|
||
|
|
* Simply replace AudioEffectDelayExternal with BAAudioEffectDelayExternal
|
||
|
|
* and it should work the same as the default Audio library.
|
||
|
|
*
|
||
|
|
* This demo mixes the original guitar signal with one delayed by 1.45 ms
|
||
|
|
* the the external SRAM MEM0 on the TGA Pro
|
||
