Calibration failed

[Didier B]

Is that the only error message you get?

Press the Reset button close to the detected IMU in the I2C sensors tab.

Open a terminal and type
repeat the calibration and paste here the complete error.

Code:

cd /home/pi/.config/openplotter/imu
RTIMULibDemoGL

I did the complete calibration process :

• - select IMU (default)
  
• - select fusion mode (RTQF, default)
  
• calibrate accelerometers, save min/max ;
  
• - calibrate magnetometers, save min/max, get the >200 count for each octant
  
• - launched 'process ellipsoid'
  

Here is the terminal output :

I may have missed something, as my 7" display (800x480) doesn't allow me to visualise the whole calibration window, but only its upper part...
