It helps a lot so far.\r\nI met this weird issues, and I tried google it but can't find any answer, I hope you can give me some idea on how to solve this problem.\r\n\r\nSystem setup:\r\nOS: windows 10\r\nIIC lib: i2cdevlib\r\nSensor: SparkFun 9DoF Razor IMU M0\r\n\r\nAfter calibrate the magnetometer (http://diydrones.com/profiles/blogs/advanced-hard-and-soft-iron-magnetometer-calibration-for-dummies), every thing look fine, the output is quite stable. However, when I rotate the sensor alone yaw axis, the output value did change, and then slowly go back to the original value.  \r\nAttached is the out put:\r\n![2017-06-20](https://user-images.githubusercontent.com/15796782/27371701-74660d6c-5694-11e7-96d0-92477ef4ef98.png)\r\nAs you can see, the blue line represents yaw, I stopped rotating (marked in red circle in the picture) but the output value is not stable after that.\r\n\r\n![14001-04](https://user-images.githubusercontent.com/15796782/27372208-5cdd087e-5696-11e7-8dc0-c77e64fac6ac.jpg)\r\nAs for the sensor, I place this side up.\r\n\r\nThanks,\r\nAlex\r\n"},"comment":{"url":"https://api.github.com/repos/kriswiner/MPU9250/issues/comments/390810857","html_url":"https://github.com/kriswiner/MPU9250/issues/153#issuecomment-390810857","issue_url":"https://api.github.com/repos/kriswiner/MPU9250/issues/153","id":390810857,"user":{"login":"Patrickyp","id":6183727,"avatar_url":"https://avatars0.githubusercontent.com/u/6183727?v=4","gravatar_id":"","url":"https://api.github.com/users/Patrickyp","html_url":"https://github.com/Patrickyp","followers_url":"https://api.github.com/users/Patrickyp/followers","following_url":"https://api.github.com/users/Patrickyp/following{/other_user}","gists_url":"https://api.github.com/users/Patrickyp/gists{/gist_id}","starred_url":"https://api.github.com/users/Patrickyp/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/Patrickyp/subscriptions","organizations_url":"https://api.github.com/users/Patrickyp/orgs","repos_url":"https://api.github.com/users/Patrickyp/repos","events_url":"https://api.github.com/users/Patrickyp/events{/privacy}","received_events_url":"https://api.github.com/users/Patrickyp/received_events","type":"User","site_admin":false},"created_at":"2018-05-21T23:16:19Z","updated_at":"2018-05-21T23:16:19Z","author_association":"NONE","body":"HI kRIS,\r\n\r\nIs the fusion rate the number that is printing out in debug mode as \"rate = 1301.90 hz\"?  When I turn the magnetometer 90 degrees it takes 3-5 seconds for the serial monitor to get to the correct value is this delay normal for 1300 hz rate?"}}
