使用DRV10964和STM32L496AG体验平滑的电机操作

/*!
 * @file 
 * @brief Brushless2 Click example
 * 
 * # Description
 * This application controlled speed motor.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initialization driver enable's - GPIO, PWM initialization
 * 
 * ## Application Task  
 * This is a example which demonstrates the use of Brushless 2 Click board.
 * Brushless 2 Click communicates with register via PWM interface.
 * Results are being sent to the Usart Terminal where you can track their changes.
