Testers needed for in-flight compass learning


(tridge) #61

thanks to everyone for testing this feature, much appreciated!
It is now merged into master, so it can be tested with the ‘latest’ auto-builds.
@master-of-desaster-8 the Pixhawk4 build should appear on firmware.ardupilot.org in the next couple of hours
@marco3dr I know you suggested some improvements in the buzzer and LED patterns - we can do that as a separate PR after this one
Cheers, Tridge

Don’t forget about the MAVLink message @tridge

:slight_smile:

You can actually do it via MAVLink now, using a param_set_value(“COMPASS_LEARN”, 3), but I agree that a better interface would be nice


(Luís Vale Gonçalves) #64

ok, this should be enough :slight_smile:

Am I the only one having trouble with this with Pixracer? The firmware in your link caused the RC input to quit and the same thing happens when I load master now (3.7-dev from today). Incidentally the Frsky passthrough telemetry stops also. I load beta back on and all good. Seems odd because another user in this thread said he had no problem in this regard with a Pixracer

Hi Dave,

just tested: The firmware works fine on my (original) Pixracer. No problems with the RC input (FrSky) or the Frsky passthrough telemetry.

Thanks Rolf, that’s 2 Pixracers at least working fine and mine not so I’ll investigate for another problem. I have 2 other PixRacers to try also.


(Luís Vale Gonçalves) #68

Also no issues with master on a PixRacer R14 still from AUAV.

Hi Tridge,
could You tell me how to get the “expected_mag(GPS,ATT).x” graph in the MAVExplorer?
To graph the “MAG.MagY” is no problem, but on the first one I fail.
Would be interresting to see how accurate the calibration was.

Cheers,
Markus

Hello Tridge,

Yesterday weather was nice - so I could test the new function.
At the Mavlink I got the follwo message:

I apologize for the unrelated question.
But I’m curious to ask a question.

How does the plane change with compass learning?
Does it show better flight performance in poshold, althold or auto?


(Geert Folkertsma) #72

Question: what is the difference between this new learning and the other learning options? (COMPASS_LEARN=1,2)

The Advanced Compass Configuration (http://ardupilot.org/plane/docs/common-compass-setup-advanced.html#common-compass-setup-advanced) says " * Automatically learn offsets : TBD."


(Markus Greinwald) #73

Hi Tridge,

Today I got a succsesfull calibration.


Cheers Markus

This is a bit off topic but ran into it while testing in-flight compass. I had random rc commanded flight mode changes after a master update. I just saw that you made a change to rc commands and updated. Solved the issue, now all is well with the world😎. Thanks for all your efforts and skill, this just keeps getting better.
Cheers, Randy
