使用 VN9D5D20FN 和 STM32F446RE 实现电阻性与感性高端负载的开关控制

 * @file main.c
 * @brief SolidSwitch 9 Click example
 *
 * # Description
 * This example demonstrates the use of the SolidSwitch 9 Click board by 
 * gradually increasing and decreasing the output duty cycle of each output channel one by one. 
 * After each update, the output is enabled and the diagnostic status is cleared.
 *
 * The demo application is composed of two sections:
 *
 * ## Application Init
 * Initializes the logger and the Click board driver, and applies the default configuration.
 *
 * ## Application Task
 * Adjusts the output duty cycle from 0% to 100% and back to 0% for each channel sequentially 
 * and clears the diagnostic status after each duty cycle update. The currently active output
 * channel number is logged on the USB UART.
