 * @brief Current Limit 4 Click Example.
 *
 * # Description
 * This library contains API for the Current Limit 4 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 and ADC module and log UART.
 * After driver initialization, the app executes a default configuration 
 * and set the minimum current limit threshold to 1.0 [A].
 *
 * ## Application Task
 * This example demonstrates the use of the Current Limit 4 Click board. 
 * The demo application displays the source current proportional to the load current
 * and an appropriate message when the current reaches the limit.
 * Results are being sent to the UART Terminal, where you can track their changes.
