 * @brief DIGI IO Click example
 *
 * # Description
 * This example demonstrates the use of DIGI IO Click board by setting and reading 
 * the DOI channels state.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the Click default configuration which sets 
 * the DOI1 and DOI2 as output and the DOI3 and DOI4 as inputs.
 *
 * ## Application Task
 * Toggles the DOI1 and DOI2 pins state and then reads the status of all four DOI pins
 * and displays the results on the USB UART approximately once per second.
