说明：  介绍了一种用加速度传感器测量振动位移信号的方法。 该方法采用频谱转换法，首先将加速度谱转换成位移谱，再计算出位移谱中每个频率分量对应的幅值 、圆频率和初相角，最后对各位移分量进行叠加得到振动位移的时间历程。 验证试验结果表 明该方法 可行 ， 精度可满足工程 实践的需要 。(A method of measuring vibration displacement signal with acceleration sensor is introduced. In this method, the acceleration spectrum is first converted into displacement spectrum, and then the corresponding amplitude, circular frequency and initial phase angle of each frequency component in the displacement spectrum are calculated. Finally, the time history of the vibration displacement is obtained by superimposing each frequency component. The test results show that the method is feasible and the accuracy can meet the needs of Engineering practice.)

单片机虚拟串口仿真图，里面有虚拟串口软件和串口调试助手，还有用proteus进行的仿真图，不用开发板一样进行仿真，只能说proteus太强大了。只要你想不到的，没有他做不到的！(Virtual serial port emulation chip chart, which has a virtual serial port software and serial debugging assistant, as well as performed with proteus simulation map, not the same simulation development board can only say proteus too strong. As long as you think, no he can not do!)

IIC驱动,改变宏定义管脚即可直接使用，非常方便！！！(IIC Driver, Change the macro definition pin can be directly used, very convenient!!!)
