Hello, everybody.
I have repeated problems with my IMU. After I have calibrated the magnetic course does not match the real course. Some differences are more than 100°.
I am looking for the cause. Is it because of the IMU or has it other reasons.
To possible culprits.
I make mistakes in handling.
The IMU is about 30cm away from the rest of the system and there are no power cables nearby.
I drive in Germany on channels which are bordered with steel walls. (Do you know that or do you need a picture?)
I am using a mpu9255 bought cheaply from China. (Could it be that there are different qualities? Where do you get your parts from?)
Greetings Jürgen
