 * @file main.c
 * @brief Current Limit 10 Click example
 *
 * # Description
 * This library contains API for the Current Limit 10 Click driver for the current limiting 
 * to a certain value and displays the sources a current proportional to the load current [A].
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of I2C module and log UART.
 * After driver initialization, the app executes a default configuration.
 *
 * ## Application Task
 * This example demonstrates the use of the Current Limit 10 Click board. 
 * The demo application sets the current limit threshold of 750 mA and 
 * checks the fault flag for overcurrent conditions.
