 * @file main.c
 * @brief Inclinometer Click example
 *
 * # Description
 * This example showcases ability of device to configure it for 
 * resolution and read Axis/Angle/Temperature data.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of the Host communication modules(UART, SPI). 
 * Sets default configuration where powe-up sequence is done with 
 * selecting MODE1 and enabling output on Angle channels. 
 * Read status and checks WhoAmI register. In the end example type
 * is selected( for reading Axes, Angles or Temperature data ).
 *
 * ## Application Task
 * Depending on the example type selected task is reading different data.
 * If EXAMPLE_AXIS selected it reads 3 axes values in range of -1<->1g. 
 * If EXAMPLE_ANGLE is slected it reads 3 angle values in range of 
 * -90<->90deg. EXAMPLE_TEMP reads temperature data from device in degC.
 *
 * @note
 * For Click board to work on ARM boards you need to pull-up MISO line.
