Hi..
I am not sure how the air start ground start work for standalone operation.
When I compile and run with "#define ENABLE_AIR_START 0" It does calibration and returns good values.
When I compile and run with "#define ENABLE_AIR_START 1" I can not get calibration going, and the values is all over the place.
How do does the "#define GROUNDSTART_PIN 8" work?
Does it do calibration on startup with pin high or pin low? I did try to keep it high and low on startup, but I could not see any Led do calibration flashing, as it would in "efine ENABLE_AIR_START 0".

I'm not sure if this helps you or not, but if you connect an old old ardupilot pin 6(I think it is) to the IMU pin 8, it can get a groundstart signal. I'm guessing it is normally low and then gets a high and that triggers the groundstart, so you'd need a way to mimic that.
