使用LC709204V和STM32F446RE提供精确的剩余电池电量估算

 * @brief BATT-MON 5 Click example
 *
 * # Description
 * This example demonstrates the use of BATT-MON 5 Click board by reading
 * the battery cell voltage and the relative state of charge (RSOC).
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the Click default configuration.
 *
 * ## Application Task
 * Reads the battery cell voltage and the relative state of charge (RSOC) and
 * displays the results on the USB UART approximately once per second.
 *
 * @note
 * For the communication with the Click board to work, the battery needs to be connected.
 * The Click board is configured by default for a 2000 mAh battery pack capacity.
