使用A3967和STM32G474RE使控制双极步进电机更轻松、更高效

 * @file main.c
 * @brief Stepper Click Example.
 *
 * # Description
 * This example demonstrates the use of the Stepper 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 performs the Click default configuration.
 *
 * ## Application Task
 * Drives the motor clockwise for 64 full steps and then counter-clockiwse for 128 half
 * steps with 2 seconds delay before changing the direction. All data is being logged on
 * the USB UART where you can track the program flow.
 *
 * @note
 * Step Motor 5v [MIKROE-1530] is a fully compatible stepper motor for this Click board:
