Control both industrial and consumer-grade stepper motors with DRV8424 and ATmega328P

/*!
 * @file main.c
 * @brief Stepper 19 Click example
 *
 * # Description
 * This example demonstrates the use of Stepper 19 Click board 
 * by driving the motor in both directions for a desired rotation angle.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * The initialization of I2C module and log UART.
 * After driver initialization, the app sets the default configuration.
 *
 * ## Application Task
 * The application task represents an example that demonstrates 
 * the use of the Stepper 19 Click board with which the user can sequentially move the motor. 
 * The first part of the sequence executes the clockwise/counterclockwise motor movement 
 * for an angle of 90 degrees with a step speed of 50%, 
 * all the way to the last sequence of the same movement routine 
 * of 360 degree angle with a step speed of 90%. 
 * Results are being sent to the UART Terminal, where you can track their changes.
