There is a problem. My autopilot card is standing flat. What can be the problem?
When you calibrated the Pixhawk accels/gyros, did you select “Choose
Roll90 for the Autopilot Orientation selection”?
Yes, I select Roll90. But there is a mistake. In addition I use Navio2.
Apparently Navio does not calibrate the accels/gyros the same way that the Pixhawk does.
Maybe Jacob will chime in here and help you out.
If you want the horizion to be flat while the autopilot is flat, then select “None”. The advice for Roll90 only applies to our BlueROV2 vehicle we sell. Most people here use BlueROV2, so @TCIII assumed that you were too.
Thanks a lot.
