使用 MAX77751 和 STM32F410RB 实现单节锂离子/聚合物电池的快速 USB-C 充电

/*!
 * @file main.c
 * @brief Charger 24 Click example
 *
 * # Description
 * This example demonstrates the use of the Charger 24 Click board. The application 
 * initializes the device, enables battery charging, and continuously monitors the 
 * charging and USB power status. It displays whether the battery is currently 
 * charging, fully charged, or if no input is detected, as well as whether the USB 
 * power is valid.
 *
 * The demo application is composed of two sections:
 *
 * ## Application Init
 * Initializes the logger and the Charger 24 Click driver and enables charging while disabling boost mode.
 *
 * ## Application Task
 * Periodically reads and logs the charging and USB power status.
 *
 * @note
 * Ensure a valid USB input source and battery are connected to observe status transitions.
