    How to output Euler angle by BSXLite?

    Dear All

    BSX Lite is very handy because it can outputs Quaternion. Although Euler angle is much less accurate than a Quaternion, and there is a problem with the Gimbal lock, there are still many Apps in reality who want to read the Euler angle directly. Of course, I also know that the BNO050 may be able to export Euler directly, but it lacks other features.
    I wonder who has tried to convert the Quaternion into Euler angle, or even calculate the Euler angle directly with 9DOF? Can someone share the code?
    The conversion of the Quaternion into the Attitude angle (absolute Euler angle) needs to solve a matrix, then, the solution of the Attitude angle should attach a credible range of value (Gimbal lock problem)?

    I am using  BSX Lite at BMX160, C# program.

    Thanks!

    Andy

    Hi Andy,

    You should call the bsx_get_orientdata_euler_rad function for Euler Angles directly from BSX.

    If you are using floating point, then the gimbal lock becomes less of an issue.

    Hi 

    Yes, I tried calling the bsx_get_orientdata_euler_rad, but the output data doesn't change, seems it jammed. The code is so simple, what exactly did I do wrong?  please see follows code. Andy
