 * @file main.c
 * @brief MUX 5 Click example
 *
 * # Description
 * This example demonstrates the use of MUX 5 Click board by mapping the common connection
 * A and B to different channels every 5 seconds.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the Click default configuration.
 *
 * ## Application Task
 * Maps the common connection A and B to different channels every 5 seconds, and displays
 * the channels state on the USB UART.
