I have a “new” Pixhawk 2.4.8 from an Amazon seller. My older Pixhawk board was getting flaky readings from the Z accelerometer so I replaced it. I’m very much a novice, I build a quad like 4 years ago, did a couple hover tests, and haven’t really touched it until the past month or so.
Anyway, since my past unit went bad, I have my Pixhawk connected via USB (2 meter cable) to my laptop, no other hardware connected. I’ve tried in Mission Planner and QGroundControl, and I can’t get the compass calibration to work. The green bar does not move/fill at all when I move the Pixhawk around.
I’m not sure whether I have a bad board or what.
First off, is there a way to view the readings from the onboard compass(es) to see if they’re responding when I move the Pixhawk around? At least in QGC, the heading appears to change when I rotate the device, but that may just be because I calibrated the accelerometers and it can tell it’s moving.Second, if the compass does work, how do I get the calibration to work?
I intend to use the Pixhawk with a Neo-7M GPS but if the board is bad I will return it for replacement before I go on with rebuilding my quad.
I have Copter 4.0.3 loaded if that matters. This seems more like hardware but what do I know?
Thanks!
