Re: [Paparazzi-devel] Error calibrating accelerometer of Lisa m2.0

[Felix Ruess]

Hi,

you probably didn't take enough measurements with the IMU set on all 6 sides...

Some days ago I already tried to make the script a bit nicer for this case, so it will still show the plot (if enabled with the -p option) if the optimization failed.

So you could checkout the master branch and re-run the calibration with the -p option to show the measurements.

In any case you probably need to collect new data and create a new log file for calibration.

Hope that helps,

Felix

Hi,

When calibrating accelerometer using calibrate.py with -s ACCEL option, it
gives the following error message:

*Optimization error: Number of calls to function has reached maxfev = 1400.
Please try to provide a clean logfile ....*

But with -s MAG option,it will be OK.How can I solve this?Thanks for any
help.
