Build your BLDC motor driver with DRV8313 and STM32F407VGT6

/*!
 * @file main.c
 * @brief Brushless 20 Click example
 *
 * # Description
 * This example demonstrates the use of the Brushless 20 Click board by driving the 
 * motor in both directions at different speeds.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the Click default configuration.
 *
 * ## Application Task
 * Drives the motor in both directions and changes the motor speed every 3 seconds approximately.
 * The current driving direction and speed will be displayed on the USB UART.
