 * @brief UT-S 7-SEG B 2 Click example
 *
 * # Description
 * This example demonstrates the use of the UT-S 7-SEG B 2 Click board
 * by writing and displaying the desired numbers on the screen.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initialization of SPI module and log UART.
 * After driver initialization, the app executes a default configuration.
 *
 * ## Application Task
 * The demo application draws numbers, in hexadecimal format, 
 * from 0h to FFFh on the top segment group and from FFFh to 0h on the bottom segment group.
 * Results are being sent to the UART Terminal, where you can track their changes.
