 * @file main.c
 * @brief eFuse 7 Click Example.
 *
 * # Description
 * This library contains API for the eFuse 7 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 Click module and UART log, then performing default 
 * configuration and setting a current limit to 1 A.
 *
 * ## Application Task
 * This example demonstrates the use of the eFuse 7 Click board.
 * Reading user's input from UART Terminal and using it as an index 
 * for an array of pre-calculated values that define the current limit level.
 * Results are being sent to the UART Terminal, where you can track their changes.
