IMU calibration - vincenthure - 2023-02-20
My setup is
- Raspi 4B 8G
- IMU mpu 9250/6500
- Open plotter 3.5.0
- Pypilot 3.2.11
Everything is working fine, thank's to the community.
I have done compass, accel and level calibration in the Calibration window of pypilot.
that's work well pitch and roll are Ok.
To have the right Heading I have to enter a offset of 30.
When I do that pitch and roll do not work well :
rolling the IMU make now moving both roll and pitch data!
It make no sense for me because the offset of the heading should not affect roll and pitch.
How is it working for you?

It's a known feature of pypilot; see https://forum.openmarine.net/showthread.php?tid=2946&pid=17922#pid17911

Offset of the heading changes the axis relative to which you measure pitch and roll.
So pitch and roll would change if you modify offset. Only at level zeros would match.
