Quaternion transformation to Roll-Pitch-Yaw angles

See original GitHub issue

When you see the gyroscope integration, you can see that the Y-axis spins 1 negative turn then 1 positive turn. When you see the estimated and reference orientation, the Yaw simply doesn’t follow that. I agree reference Yaw and reconstructed Yaw are similar because their quaternions are very very close. the problem isn’t about ±2pi. The problem comes that the to_angles()conversion doesn’t get you the real movement.

Taking code sample from the documentation

attitude = ahrs.filters.Madgwick(acc=acc_data, gyr=gyro_data)

No, I switched to a different approach due to the approaching deadlines. This is still unsolved.

do we have any update on this weirdness?
