  • Wii Remote Yaw Calibration

    Hello everyone!

    I am having issues regarding calibration of my yaw on my WiiPlus remote. Essentially, it seems that every time that the remote calibrates, my 0 to 1 range is in a different place. What I mean is that sometimes 1 is right in front of me, sometimes it's to my left, and sometimes it's behind me. This is difficult as it's inconsistent data.

    I am working with PD, and I want to simply program it so that if I hold the Wii remote in the middle, it is at .5, left is 0 and right is at 1. Does anybody have any suggestions regarding this? Is there a right and wrong way to calibrate your Wii remote? I tried to look for key words in the manual and couldn't find the answer.

    Thank you so much!

    Are you using the accelerometers or motion-plus based value of yaw?
    With proper calibration, the yaw direction should always be the same.

      Thanks for the reply.

      I am using the motion-plus based value of yaw. I decided to set a reset calibration button, and that has been working relatively consistently. Once in a while, it seems like the yaw gets off track really easily, and at times it's pretty steady. I've been messing around with it, and I feel like it works much better now.

        When you use motion-plus based value, yaw is the only value (as opposed to roll and pitch) that is not influenced by the accelerometers and is just a integrated value of the raw gyros. Because of this integration process and the specifications of the gyros, yaw is subject to drifting, hence the "reset calibration" event.

        I am surprised though that yaw has such different values right after calibration.

        If it occurs again, and you can kind of isolate a way to reproduce the problem, please let me know!

          I restarted Osculator and it actually seems to be far more responsive than before. Using the reset button seems to have helped quite a bit as well. I think I also figured out that I'll basically have to have a reset button just in case. If I move the controller to far left and then try to come back, the data shifts. So I have to keep resetting every time that the remote is in the front position.
