 *
 * # Description
 * This example demonstrates the use of BATT-MON 4 click board by reading
 * the battery voltage and the chip internal temperature.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and logger.
 *
 * ## Application Task
 * Reads the chip DIE temperature and voltage from BATT IN and BATT OUT and displays
 * the results on the USB UART approximately once per second.
