// I2Cdev and MPU6050 must be installed as libraries, or else the .cpp/.h files
// for both classes must be in the include path of your project
#include "I2Cdev.h"

// Arduino Wire library is required if I2Cdev I2CDEV_ARDUINO_WIRE implementation
// is used in I2Cdev.h

测试结果

按照上图接好线,烧录好代码,上电后,通电后,我们可在软件串口监视器中看到相对应数值,如下图。
