使用PI4IOE5V96248和ATmega328P改变数据采集管理和控制方式

 * @file main.c
 * @brief Expand13 Click example
 *
 * # Description
 * This example demonstrates the use of Expand 13 click board, 
 * by writing data to all six ports and then reading back the status of the ports. 
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and enables the click board.
 *
 * ## Application Task
 * Sets the pins of all ports and then reads and displays their status on the 
 * USB UART approximately once per second.
