I’m having a little problem on by Flight Controller with Mission PLanner;
My drone comes from Inav, and i want to try it with arducopter, since i added some rangefinders.
Anyway, on Inav, my board orientation was YAW 270° (arrow point on the left on the quadcopter);
In mission planner, when i do the same parameter, i have an inversion beetween left and right (when rolling left, horizon roll right and vice versa); up and down are OK;
So i tryed another YAW, with 90°; and i have good left/right but bad Up/down (horizon goes down when nose up and vice versa)
I tryed all the YAW orientation possible, none are working good;
Any idea what it can be? What orientation should I choose?
Thanks for your help!
@lezabour have you double checked you’re using the correct ardupilot firmware version for your exact board type? mind the CTR requires using the MatekF405 fw, not the -STD type as it’s using a different IMU / default rotation. see https://ardupilot.org/copter/docs/common-matekf405.html#variants for reference.
Thanks for your help;
Yes i choose the right firmware, the MatekF405/arducopter_with_bl.hex
Their is no compass on the board, its the external compass of GPS; GPS/compass has normal orientation (arrow pointing forward);
This is my GPS/compass: https://robu.in/product/ublox-neo-m8n-gps-for-apm-and-pixhawk-flight-controller/
normally compass as same orientation as GPS/Arrow on it, so normally i do not have to change compass orientation;
–>i will recheck that anyway
I did change AHRS to 270 (and tryed all other like explained before) with the results you know
also, i did try to disable compass to see if it affect it, no change…
@lezabour can you please check if you get correct response with your board in default orientation and AHRS_ORIENTATION set to 0 = none.
hmmm! We may have a clue!
@vierfuffzig i just did, and no, i don’t have the correct response.
right and left are inverted ;(
(when rolling right, HUI Horizon roll left)!
maybe this could be the problem?
ok i thing i found i reflash with last version and updated mission planner and now seams OK!
will try to fly and check it directly
thanks for help
@lezabour - I face the same issue with my Matek F405 FC. Can you, please, tell which exactly version of
- Arducopter and
- Mission Planner
did you use?
How was your test fly?
I managed to make it work with 4.0.5, by changing the board orientation to 270°
Test flight has been ok
