Control any common DC motor using Discovery kit with STM32F407VG MCU and STM32F407VGT6

/*!
 * @file main.c
 * @brief DC Motor 12 Click example
 *
 * # Description
 * This example demonstrates the use of DC Motor 12 click board by controlling the speed
 * of DC motor over PWM duty cycle as well as displaying the motor current consumption.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the click default configuration.
 *
 * ## Application Task
 * Changes the operation mode and motor speed by setting the PWM duty cycle and then calculates
 * the motor current consumption for that speed. All data is being logged on the USB UART
 * where you can track changes.
 *
 * @note
 * The click board swiches should be set as follows: SW 1-2-3-4 : H-H-L-L
 * This sets the click board as a SPI controlled single-channel device so 
 * the motor should be connected to OUT1/2 and OUT3/4.
