使用 TB62269 和 STM32L073RZ 释放双极步进电机的全部潜力

/*!
 * @file main.c
 * @brief MultiStepperTB62269 Click example
 *
 * # Description
 * This example demonstrates the use of the Multi Stepper TB62269 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 200 steps and then counter-clockiwse for 100 steps with
 * 2 seconds delay before changing the direction.
 * Each step will be logged on the USB UART where you can track the program flow.
