使用 BQ25188 和 STM32F302VC 实现智能单节电池充电

/*!
 * @file main.c
 * @brief Charger 29 Click example
 *
 * # Description
 * This example demonstrates the use of the Charger 29 Click board.
 * The application initializes the device and periodically checks the charging status.
 * The status is displayed over the UART terminal and reflects whether the battery is 
 * charging in constant current (CC) mode, constant voltage (CV) mode, fully charged,
 * or not charging.
 *
 * The demo application is composed of two sections:
 *
 * ## Application Init
 * Initializes the logger and the Charger 29 Click driver and applies default configuration.
 *
 * ## Application Task
 * Periodically reads and logs the charging status once per second.
