 * @brief SmartMic Click example
 *
 * # Description
 * This example demonstrates the use of Smart Mic Click board by programming 
 * it with 4 different keywords, and then waiting for a keyword event, 
 * parsing it and displaying on the USB UART.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the Click default configuration 
 * which programs the device with system config, firmware, and 4 keywords 
 * ("Hello VoiceQ","Switch The Light","Next Song","Baidu Yixia") binaries.
 *
 * ## Application Task
 * Waits for a keyword event, parses it and displays on the USB UART 
 * an appropriate message for the detected keyword.
