 * This application reads the voltage measurement and displays the results on the USB UART.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization the driver and logger.
 * 
 * ## Application Task  
 * Reads the raw ADC measurement once per second and converts it to the proportional voltage level.
 * All data are being displayed on the USB UART where you can track their changes.
