Achieve smoother and more precise control of stepper motors with TMC2240 and STM32F756ZG

/*!
 * @file main.c
 * @brief Silent Step 4 Click example
 *
 * # Description
 * This example demonstrates the use of the Silent Step 4 Click board by driving the 
 * motor in both directions for a desired number of steps.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the Click default configuration.
 *
 * ## Application Task
 * Drives the motor clockwise for 200 full steps and then counter-clockiwse for 200 half
 * steps and 400 quarter steps with 2 seconds delay on driving mode change. All data is
 * being logged on the USB UART where you can track the program flow.
