It's not clear how X Y Z axis are oriented.
Usually IMU returns accel Z in fractions of G from 0 to 1. In example it is negative 1.
It gets really confusing how to use it with real IMUs.
Some Ard…

Hi Kris, this is the second time I am writing to you, the truth is that your code is great!
Beyond that, I am having problems in the convergence of the data when using the Madgwick and Mahony Filters…

In the [documentation](https://ahrs.readthedocs.io/en/latest/filters/mahony.html) of the Mahony filter it is stated that \dot{\hat{q}} is a function of \hat{b} where \hat{b} results from integrating -…

hello tkj electronics. Well read your good library, it really helped me understand what the kalman filter is.
Anyway, I wanna know how to calibrate mpu6050 accel,gyro offsets using kalman filter. In …

Please tell something over how to use the getattitude 1 and 2 values using your mpu6050 library.

the original Madgwick and Mahony filter are available in 6DoF and 9DoF versions (http://x-io.co.uk/open-source-imu-and-ahrs-algorithms/). It would be great if the project enabled the use of 6DoF as we…

Hello,
Thank you for this very useful code.
I'm facing an issue with the yaw estimation using Madgwick/Mahony filters.
I povide ideal sensors measures in ENU frame :
- aX = [0.0] * n

Both Madgwick and Mahony filter implementations are using a fixed `sample_period`. However in non real-time systems, it is more accurate to directly pass the time delta between two measurements:
``…

The AHRS library appears to incorrectly compute the z-axis of the gravity vector for at least the Madgwick and potentially the Mahony filter.
This issue pertains to the library, not specific hardwa…
