 * \brief VCPmonitor Click example
 * 
 * # Description
 * The VCP Monitor Click is add-on board power monitor system. This Click board is 
 * based on precision digital current and power monitor with low-drift, integrated 
 * precision shunt resistor. 
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initiaizes the driver, and checks the communication by reading the device and manufacture IDs.
 * After that, performs the device default configuration.
 * 
 * ## Application Task  
 * Displays the voltage, current, and power measured by the sensor on the USB UART every 2 seconds.
