 * @file main.c
 * @brief Inclinometer 3 Click example
 *
 * # Description
 * This library contains API for the Inclinometer 3 Click driver.
 * The library initializes and defines the SPI drivers to 
 * write and read data from registers, as well as the default configuration 
 * for the reading accelerator and temperature data.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * The initialization of the SPI module, log UART, and additional pins.
 * After the driver init, the app executes a default configuration.
 *
 * ## Application Task
 * This example demonstrates the use of the Inclinometer 3 Click board.
 * Measures and displays acceleration data for the XY-axis [mg] 
 * and temperature [degree Celsius] data.
 * Results are being sent to the UART Terminal, where you can track their changes.
