 * @brief PROFET 10A Click Example.
 *
 * # Description
 * This example showcases the ability of the PROFET 10A Click board.
 * It configures Host MCU for communication and then enables 
 * and disables output channel. Besides that, it reads the voltage 
 * of IS pin and calculates current on output.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of the communication modules(ADC and UART) 
 * and additional pins for controlling the device.
 *
 * ## Application Task
 * On every iteration of the task device switches between 
 * DIAGNOSTIC and OFF mode while it reads the voltage of IS pin 
 * and with that calculates current on output.
 * 
 * @note
 * Formula for calculating current on load: 
 * I_load = voltage(IS) x kILIS / 1.2 kΩ
 *
 * Click board won't work properly on the PIC18F97J94 MCU card.
