 * @file main.c
 * @brief eFuse Click Example.
 *
 * # Description
 * This library contains API for the eFuse Click driver.
 * This demo application shows use of a eFuse Click board™.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of GPIO module and log UART.
 * After driver initialization the app set default settings.
 *
 * ## Application Task
 * This is an example that shows the use of an eFuse Click board™.
 * The Electronic Fuse is an electrical safety device that operates to 
 * provide overcurrent protection of an electrical circuit.
 * The intervention threshold is programmed by the Rs resistor.
 * The device disconnects the load if the power overcomes the pre-set threshold, 
 * for example if Vset = 3.9 kOhm, Vin = 12 V, 
 * the intervention threshold is set approximately to 875 mA.
 * Results are being sent to the Usart Terminal where you can track their changes.
