 * 
 * # Description
 *  The demo application displays the volume change using AudioAmp 6 Click.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Configuring Clicks and log objects.
 * Select mode and sets output on the enable state.
 * 
 * ## Application Task  
 * Changes the gain settings ( 20dB - 26dB )
 * 
 * *note:* 
 * Sets the input voltage from 3.5V to 14.4V.
