Problems in Magnetometer Calibration #6
Description
Hello,
I have just bought the servo and cut the wood to calibrate my IMUs.
My calibration went fine with the accelerometer and gyroscope (I hope so), at least I could visualize the colored lines and dots move as I moved my IMU. The problem was when I started calibrating the magnetometer. I had it all set up with the servo but when I ran the processing sketch the green dot didn't leave the center of the sphere. And I tried to upload this only-dotted-calibration-data to my motioner IMU and it failed with this message:
It seems like a bug in the sketch.
Can someone help me?
