 * @file main.c
 * @brief MagAccel Click example
 *
 * # Description
 * This library contains API for the MagAccel Click driver.
 * The library initializes and defines the I2C drivers to 
 * write and read data from registers, as well as the default 
 * configuration for reading accelerator data.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * The initialization of the I2C 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 MagAccel Click board.
 * Measures and displays acceleration data for the X-axis, Y-axis, and Z-axis 
 * and the presence of a magnetic field. 
 * Results are being sent to the UART Terminal, where you can track their changes.
