Hey Kris,
Thank you for your code. I'm trying to implement it on my IMU. However, I have some questions about the magnetometer calibration and NED reference.
I read through the code for the cali…

In the sample code, MPU9250BasicAHRS_t3.ino, it appears the sensor is read about 200 times a second, but the filter is updated on every loop, or about 10-15 times as fast. Those extra filter updates a…

Hello Kris, first of all congratulations on all your work, it is simply amazing.
I am trying to synchronize two MPU-9250 in order that at any time I can know what is the difference in angles betwee…

Hello Kris -
Many thanks for your excellent code for the Teensy and MPU9250.
I am trying to use this as the basis of an antenna rotator controller, but am running into a few problems with compass …

Hello,
I might be missing something basic. When I run visual odometry only, it works Ok, even though it is a bit unstable.
So I implemented wheel encoder odometry, which also works Ok with rtabm…
