Following my issues described here, I made some test with the quad standing still on the bench and pre-arm logging enabled.
I’m seeing strange behaviors for IMU.GyrX and IMU.GyrY that manifest into huge HUD drifts. IMU.GyrZ, IMU2.GyrX, IMU2.GyrY and IMU2.GyrZ look good.
Here is what I see at random times. This are pre-arm data with the quad standing still on the table:
When this happens, the HUD drift a lot (up to more than 45°) and I think that flighting in these situations will not be a good idea.
Sometimes, there is no suddenly changes in the values but a (fast?) regular drift of the values:
In this case, the HUD drift only a bit (few degrees) and I think in this case the software is able to adapt to the bias.
Do you also see this kind of drift in IMU.Gyr? Is this normal? Do I have bad hardware (it’s an ebay clone)? Thank you
My logs are available here.
