使用 A4989SLD 和 STM32G071RB 实现高功率两相双极步进电机控制

/*!
 * @file main.c
 * @brief Power Step Click Example.
 *
 * # Description
 * This example demonstrates the use of the Power Step Click board by driving the 
 * motor in both directions for a desired number of steps.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and resets the device.
 *
 * ## Application Task
 * Drives the motor clockwise for 100 slow steps and 300 medium speed steps and
 * then counter-clockwise for 400 fast steps with a 1 second delay on driving mode change. 
 * All data is being logged on the USB UART where you can track the program flow.
