体验使用ADXL367和TM4C1294NCPDT的精确可靠的运动感应

 * @file main.c
 * @brief Accel22 Click example
 *
 * # Description
 * This example demonstrates the use of Accel 22 Click board by reading and displaying 
 * Accel data (X, Y, and Z axis) as well as temperature and ADC measurements on the USB UART.
 *
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes the driver and performs the Click default configuration.
 *
 * ## Application Task
 * Reads and displays the Accel data (X, Y, and Z axis) as well as temperature and ADC measurements 
 * on the USB UART every 100ms approximately.
