IMU Not behaving correctly.
#1
Hi,

I have a MacArthur HAT with the recommended IMU ... so far, so good.  It is recognised by PyPilot and I can see the "calibration" stuff ... I did the "6 sides of a box" thing and the boat is "levelled".

I've been told to leave the compass calibration "unlocked" ... and I've tried sailing around in circles, but its not working right. sailing a circle I see heading between aroud 320 degrees through 0 to 60 degrees ... looking at the calibration screens (which mean very little to me)  I can see a green circle of dots, but it is vertical, not horizontal.

Photos attached, perhaps someone could shed some light?

I don't really nderstand the need for all this calibration complexity ... mobile phones seem to be able to manage this without difficulty straight out of the box. Is it not possible to just copy whatever algorithm Android uses?
