MPU9250 heading is slowly drifting
#96
I've been watching the values over the last few days. They drifted a little, about 0.2 to 0.4 degrees in heel and ~0.5 degrees in pitch, but looks like it's oscillating around these values. Right now it's at heel 0.4° to port and pitch 3.1° nose up (started at 0.2 and 2.4 last time I leveled, which was just before writing the post above).

The raspberry Pi (and the sensor on the HAT) have remained static on my desk pretty much the whole time; I picked it up once, and when I put it back the values came back to what they were before I picked it up.

The variation at this point is probably less than what I'd expect to happen naturally in a boat at the dock.

I'll try leveling it again, just to see if I can get it to 0. (Actually, I just tried it while I was writing this, and it did come down to 0.)

To any other user reading this: after calibrating the accelerometer, if clicking "boat is level" doesn't quite set the values to 0, try it again after a little while.

Note: I'm not complaining here, I just want to add some more data points.
