 * @brief CurrentLimit7 Click example
 *
 * # Description
 * This library contains API for the Current Limit 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 I2C module and log UART.
 * After driver initialization, default settings turn on the device.
 *
 * ## Application Task
 * This example demonstrates the use of the Current Limit 7 Click board™.
 * Reading user's input from Usart 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 Usart Terminal, where you can track their changes.
 *
 * ## Additional Function
 * - static void display_selection ( void )
 *
