 * \brief AudioAmp Click example
 * 
 * # Description
 * AudioAmp Click is a stereo audio amplifier which can be controlled by using this
 * click driver.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init
 * Performs driver and log module initialization, enables I2C, turns on the AudioAmp device
 * and sends a message about init status.
 * 
 * ## Application Task
 * This is a example which demonstrates the use and control of the AudioAmp Click board.
