Pypilot compass calibration getting lost

[John0047]

That seems to have done the trick, thanks Sean.

After a restart, the compass calibration display now looks like it is after calibration.  The only thing I noted is that it requires a full 360 deg rotation to achieve a calibration, no real problem, just different to the workbook.

I suspect this change may also cure the problem I had with poor linearity, the calibration display is quite different to any I saw post restart previously.

Thanks again  John
