In other words, the sketch does not see the board inverted. After +-90 degrees, if I continue the movement (roll or pitch), the reading starts moving back to zero.\r\n\r\nIs there a parameter that controls this so roll and pitch are properly followed? If not, would you be able to suggest a spot where the code could be modified to do so? \r\n\r\nThanks in advance"},"comment":{"url":"https://api.github.com/repos/mjs513/FreeIMU-Updates/issues/comments/91088943","html_url":"https://github.com/mjs513/FreeIMU-Updates/issues/27#issuecomment-91088943","issue_url":"https://api.github.com/repos/mjs513/FreeIMU-Updates/issues/27","id":91088943,"user":{"login":"mjs513","id":5366213,"avatar_url":"https://avatars.githubusercontent.com/u/5366213?v=3","gravatar_id":"","url":"https://api.github.com/users/mjs513","html_url":"https://github.com/mjs513","followers_url":"https://api.github.com/users/mjs513/followers","following_url":"https://api.github.com/users/mjs513/following{/other_user}","gists_url":"https://api.github.com/users/mjs513/gists{/gist_id}","starred_url":"https://api.github.com/users/mjs513/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/mjs513/subscriptions","organizations_url":"https://api.github.com/users/mjs513/orgs","repos_url":"https://api.github.com/users/mjs513/repos","events_url":"https://api.github.com/users/mjs513/events{/privacy}","received_events_url":"https://api.github.com/users/mjs513/received_events","type":"User","site_admin":false},"created_at":"2015-04-09T01:54:35Z","updated_at":"2015-04-09T01:54:35Z","body":"To be honest I forgot that I added that function and uploaded it.  It was added for a comparison against a kalman filter implementation I was testing. When you rummage around the web you find that there are different axis ranges depending on the coordinate system. Had a good site that explained it been trying to find it to send to u.  Anyway give it a shot it should work"}}
