使用DRV8834和STM32L496AG控制两个直流电机或一个双极步进电机的运动

 * @file main.c
 * @brief H-Bridge 15 Click example
 *
 * # Description
 * This example demonstrates the use of the H-Bridge 15 Click board by
 * driving the motor in both directions with braking and freewheeling. 
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the Click default configuration.
 *
 * ## Application Task
 * This example is driving a motor in both directions with 
 * motor braking and freewheeling in between.
