Changing the board mounting orientation?

Posted by Guy McCaldin on February 5, 2013 at 2:44am

I'm trying to mount my APM2.5+ in a different orientation.  If I can rotate it 180 degrees so the 'Forward' indicator is facing backwards, it's going to be much easier to route the cabling.  I've searched through the manual, and looked through pages of search results here, but can't seem to find how to set AHRS_ORIENTATION to what I need it to be.

I'm happy to edit the code if that's what's necessary, but I'd prefer to be able to do it via Mission Planner.  Any ideas?

    I have been trying to mount my APM 2 at a 270 degree roll, but there seems to be some sort of coupling left over from what used to be the roll channel. As you increase pitch, you get a corresponding left roll. The APM is down 20 degrees in the photo below, and is showing roll as well. Has anyone else experienced this? The APM does not seem nearly as stable or reliable in its readings after doing a rotation either, and i'm not sure why.

    From what I remember I think that will be in the next release. Perhaps the parameter is in anticipation of that.
