sen-14001: yaw is slow to update#198617

Hi,

I have all three sensors calibrated, so I am getting very little jitter, drift, or other error. Roll and pitch are great, but yaw updates very slowly. Is there a way to speed this up?

Did you write your own code for this? If so, it is lacking. If not, what's on it?

No, I am using [1] which is based on [2], but adapted for the SEN-14001. I went through the calibration routine outlined on [3], including the extended magnetometer calibration procedure.

I think I remember reading somewhere some time ago about some older board that it had a setting for slower updates because that was desirable for flight sim applications? Maybe that is related? Am I way off?

Can you show how the yaw values are slow to update? What does the output look like? Do the values change slowly? Or do you just get less yaw values as opposed to rol and pitch?

In [1] Murphy did state that he added running filters in his code. Maybe the filter parameters are such that it introduces more lag or sluggish responses in yaw only. (for his benefit) I think that the Github Issues tab of [1] is the appropriate place to get an answer to your problem.
