 * @brief Hall Current 16 Click example
 *
 * # Description
 * This example demonstrates the use of Hall Current 16 Click board 
 * by reading and displaying the current measurements.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * The initialization of SPI module and log UART.
 * After driver initialization, the app sets the default configuration.
 *
 * ## Application Task
 * The app reads the current measurements [A] and displays the results.
 * Results are being sent to the UART Terminal, where you can track their changes.
