使用 DRV8452 和 STM32F103RB 实现平稳精准的步进电机控制

/*!
 * @file main.c
 * @brief Stepper 25 Click example
 *
 * # Description
 * This example demonstrates the operation of the Stepper 25 Click board, 
 * which is used to control a bipolar stepper motor. The application initializes 
 * the board and executes different step modes, directions, and speeds to 
 * showcase precise motor control.
 *
 * The demo application is composed of two sections:
 *
 * ## Application Init
 * Initializes the logger and Stepper 25 Click board. Configures the motor driver 
 * with default settings, preparing it for stepper motor control.
 *
 * ## Application Task
 * Moves the stepper motor in different step modes and directions at varying speeds. 
 * The motor completes a predefined number of steps in each mode, switching between 
 * clockwise (CW) and counterclockwise (CCW) directions with different step resolutions.
 *
 * @note
 * Ensure proper power supply and motor connections before running the example.
