Say goodbye to complex motor control with DRV8889A and ATmega328P

/*!
 * @file main.c
 * @brief Stepper15 Click example
 *
 * # Description
 * This library contains API for the Stepper 15 Click driver.
 * The library contains drivers for work control of the Stepper Motor.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes I2C and SPI driver and set default configuration,
 * enable the device and enable outputs mode.
 *
 * ## Application Task
 * The application task represents an example that demonstrates 
 * the use of the Stepper 15 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 85/100%, 
 * all the way to the last sequence of the same movement routine of 360-degree angle
 * with a step speed of 85/100%. 
 * Results are sent to the USART Terminal, where you can track their changes.
