If you take it off it will do that which is why it is necessary to set up a reset key in the GUI, it's on the left hand side together with setting up a button or key to switch off. Hope that helps. Also following the calibration procedure takes a bit of getting use to. It took me 5 or 6 attempts to get it right.

Thanks. I'm investigating because the gyro MUST keep values of any position of the MPU9250 and not return to horizontal values when my sensor isn't in that position. if needed you can reset values, but here there is an unknown issue with my code i think.

The coding bit is a bit beyond me to be honest. There are Edtrack videos out there that mention the drift problem. Unfortunately due to a system crash and resultant OS clean install I lost most of my stuff. I saved it all to my D drive thinking as the OS was on the C drive it would be fine. It wasn't. Of course even my wife said, why didn't you save it to a flash drive. Guess how that went down.!!!!!!!!!!!!!!!!!!

I'm near the solution, i hope. From my MPU9250 i read angular speeds in fact when i stop it, it returns zero values: i need to convert them in angles.

You'll have to explain that in English. What is your MPU9250

Thank you, read it's PDF, totally beyond me. Interesting on Edtracker if you don't have the vertical axis set in FG Calibration menu there is no drift at all. As I am not bothered about vertical axis it makes my EDT more usable for me.

Finally, things seem to go in the right direction!! i get stable values :wink:

I found the wireless version of Edtracker unreliable and sent it back. It would not stay connected whether it was because of congested 2.4 range, I have no idea and when switched off and on it took forever to connect and sometimes didn't. I got the wired version and that is so much better. You have to remember to activate it prior to launching FG but that's no big deal. Still a great piece of kit and no issues with light as other trackers with cameras do.

I've always loved wired devices mouse too, connect them and you are ready. I searched over internet to get a working code, without success so i decided to write mine. Once get the code you can do everything you want, i need it for flight sim but it is possible to drive servos for a drone. Now i need to work on raw datas.

Finally i have my headtrack with arduino and a MPU9250 working with opentrack and the hatire plugin.

A video:

I have to admit my first thought was that you had a projector dome. :oops: :lol:

:mrgreen: :mrgreen: :mrgreen: A projector dome could be great. Yes, i have already written a guide (i posted a link in the video page) but i could copy it in a wiki page :wink:
