使用 MXC6655XA 和 PIC18F57Q43 测量三轴加速度

 * @file main.c
 * @brief Accel 24 Click example
 *
 * # Description
 * This example demonstrates the use of Accel 24 Click board by reading and displaying 
 * accel data (X, Y, and Z axis) as well as temperature 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 measurements
 * on the USB UART every 100ms approximately.
