I've got the 1044_1B here now. Great it does AHRS onboard so I can check with the phidgetInspector what's going on without any of my code involved....
So I've calibrated the magnetometer, testet for metal influences (you are right, they can be severe) did further testing where only wood an plastics were near. Still, there is quite a bit of flipping and snapping going on. Sometimes it's just some tumbling motion (I can reproduce the problem I was facing), for the worst example I could produce please have a look at this video:https://share.icloud.com/photos/0398H5mlcnDfHw-3P2m5D4jyw
I realize the mag gain is cranked up all the way, however this behaviour persists even at 0.01
This way, the algorythm is completely unusable for my applycation. Did I miss something?
The IMU algorythm seems by far more reliable to display the correct motion. Is there any way to make sure the orientation persists even when the device is switched off and on again? Otherwise the installation would have to be recalibrated every morning, maybe more often, will IMU produce drift?... am I out of options?
