Precisely tracks an object's movement and orientation in three-dimensional space with ICM-42605 and ATmega328P

 * @file main.c
 * @brief 6DOF IMU 18 Click example
 *
 * # Description
 * This library contains API for 6DOF IMU 18 Click driver. 
 * The library initializes and defines the I2C and SPI bus drivers to 
 * write and read data from registers, as well as the default 
 * configuration for reading gyroscope and accelerator data, and temperature.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver after that resets the device and 
 * performs default configuration and reads the device id.
 *
 * ## Application Task
 * This example demonstrates the use of the 6DOF IMU 18 Click board by 
 * measuring and displaying acceleration and gyroscope data for X-axis, 
 * Y-axis, and Z-axis as well as temperature in degrees Celsius.
