使用 LTC3337 和 STM32L073RZ 保持电池在最佳状态

 * @file main.c
 * @brief BATTMON4 Click example
 *
 * # 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.
