 * \brief Vcpmonitor2 Click example
 * 
 * # Description
 * VCP Monitor 2 Click is a three-channel, high-side current and bus voltage monitor with alert indication 
 * function ensuring the intended application works within desired operating conditions.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initiaizes the driver, and checks the communication by reading the manufacture device ID.
 * After that, performs the device default configuration.
 * 
 * ## Application Task  
 * Displays the voltage, current, and power detected from channel 1 on the USB UART every 2 seconds.
 * It also displays the status of alert indicators.
