Control and limit the amount of electrical current with NPS4053 and ATmega328P

/*!
 * @file main.c
 * @brief Current Limit 9 Click example
 *
 * # Description
 * This library contains API for the Current Limit 9 Click driver.
 * This driver provides the functions to set the current limiting conditions 
 * in order to provide the threshold of the fault conditions.
 *
 * 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
 * and sets the current limit threshold of 460 mA.
 *
 * ## Application Task
 * This example demonstrates the use of the Current Limit 9 Click board. 
 * The demo application checks the fault flag for overcurrent conditions.
 * Results are being sent to the UART Terminal, where you can track their changes.
