LSM9DS1 Magnetometer readings make no sense?
Hello!
I am working with the LSM9DS1 and am having trouble with my magnetometer.
I tried following Application Notes in which pitch, yaw and roll are calculated but had no success. I tried tracking down the error and I found the following problem: My magnetometer reads strange values?
Currently I am calculating the norm of the measured magnetic field. I did this in two different towns, in my company and in a forrest, so there are no external magnetic fields disturbing my measurement and the error stays the same. The norm of the measured magnetic field changes significantly whenever I move or rotate the sensor. I expect the vector to have the same value, no mater to what degree my sensor is rotated, the same point in space should lead to the same vector norm.
As I said, the magnetometer is callibrated, there are no external magnetic fields, I followed the design rules for the layout in the datasheet and still I am picking up strange readings. Can someone please tell me what produces this error?
Kind regards,
Robert Reichel
