 * @brief Stepper 21 Click example
 *
 * # Description
 * This example demonstrates the use of the Stepper 21 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 400 quarter
 * steps with 2 seconds delay before changing the direction. All data is being logged on
 * the USB UART where you can track the program flow.
