 * \brief c2x20WAmp Click example
 * 
 * # Description
 * This application changes the volume level.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization driver enable's - I2C,
 * start write log and enable amplifire of 2x20W Amp Click board.
 * 
 * ## Application Task  
 * This is a example which demonstrates the use of 2x20W Amp Click board.
 * This examples first activates operation mode PLAY and set volume lvl 32,
 * after that, we increase the volume level one level ten times for 5 seconds
 * and  we decrease the volume level one level ten times for 5 seconds.
 * And finally, we set MUTE mode for next 5 seconds.
 * Results are being sent to the Usart Terminal 
 * where you can track their changes.
