 * \brief Audio Amp 5 Click example
 * 
 * # Description
 * This example consist of sending special commands for audio output control, 
 * selecting different output modes and turning on/off the audio output.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes GPIO interface on the desired mikrobus selection,
 * and performs a device init configuration.
 * 
 * ## Application Task  
 * Checks the entered command and, if the command is valid,
 * performs a device configuration which the entered command determines.
