我用最新i2cdev下载的6050DMP6代码在328P+6050板上测试，发现loop循环只有50Hz， mpu.getIntStatus(); 和mp ...

那角度准不准？不知道用来做自平衡小车需要多高的控制周期

关于dmp，我的实验结果是数据非常稳定，应该没有其它方法比这个更稳定了，数据可以直接拿来用不用任何滤波。数据也应该是最准确的了。当然稳定和准确是要付出时间代价的。默认输出中断频率是100Hz,对头文件的数组最后一位改为0可输出200Hz(这是最快的了)，对于一般的应用应该是最好的选择，如果做随动方面的设备，延迟非常明显，不过可以用角速度积分来改善（我是昨天才想到的，这几天有时间来验证一下）。希望能成功吧。如果成功，那mpu6050的稳定精确和实时性就能达到随动的要求了。

编译不通过，什么原因呢

为什么我的还是这样的错误提示啊？你是怎么让代码正确运行的啊？

错误提示？库有没有安装正确、arduino ide版本对不对。

对，就是这样。

接线图

请问你MPU6050是在哪儿买的，能给个网址吗？我的MPU6050在调整为最低刷新率后，仍为噪音数据。我看得换一个MPU了。谢谢。

编译一直通不过，怎么回事，库都是从你的地址里下的最新的，IDE用的也是最新的。不知道怎么弄了。

用DMP的话输出来的数据也是有一定偏差的，那怎么修正这个偏差呢？

我在论坛里看到单靠加速度计是等不到航向角的，那么这里的Yaw角是什么意义的角度？跟陀螺仪有关系吗？是不是在dmp中用陀螺仪的数据经过处理得到yaw？

编译不能过，是库问题！（我也遇到这问题）
将整个l2C库( https://github.com/jrowberg/i2cdevlib )下载升级，可解决问题。
