Step into the future of motor control with NCV70517 and STM32F091RC

/*!
 * @file main.c
 * @brief Stepper16 Click example
 *
 * # Description
 * This example showcases the device's ability to control the motor.
 * It initializes the device for control and moves the motor in two 
 * directions in a variety of speeds and step resolutions for 360 degrees.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes UART and SPI communication modules, and additional  
 * pins for motor control, resets device, set's default configuration,
 * and reads its ID and sets
 *
 * ## Application Task
 * First it move motor clockwise for 360 degrees in medium speed and 
 * full step resolution. Then changes direction and moves motor for 
 * 180 degrees in slow speed and quarter step, and additional 180 degrees
 * in fast speed and 1/16 step resolution.
 *
 * @note
 * Device is powered by externam VM so for communication to work Click 
 * board should be connected on power supply from 6V to 29V. At the start of
 * application user should reset device and read it's Status register 1 to clear it.
 * After that it can communicate with device and control it noramaly.
