Experience motion sensing excellence with RPI-1035 and STM32F407VGT6

/*!
 * \file
 * \brief Tilt Click example
 *
 * # Description
 * This is a example which demonstrates the use of Tilt Click board.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Configuring Clicks and log objects.
 *
 * ## Application Task
 * Detect the movement's direction
 * of RPI-1035 Surface Mount Type 4-Direction Detector on Tilt Click board.
 * Results are being sent to the Usart Terminal where you can track their changes.
 * All data logs on usb uart when the movement's direction is changed.
