minimu9-ahrs --mode raw #23

Closed NarcisaC closed 7 years ago

NarcisaC commented 7 years ago

Hello, I have followed the steps of the tutorial but just when I run "minimu9-ahrs --mode raw" this output "segmentation fault (core dumped)". How do I solve this? Also when executing "minimu9-ahrs-calibrate -b / dev / i2c-1" this other problem comes out "To calibrate the magnetometer, start rotating the IMU through As many different orientations as possible. Reading data ... Segmentation fault (core dumped)  Done Warning: Only 0 readings were provided. Optimizing calibration ... Traceback (most recent call last):   File "/ usr / bin / minimu9-ahrs-calibrator", line 147, in     Run ()   File "/ usr / bin / minimu9-ahrs-calibrator", line 95, in run     Cal1 = guess (raw_readings)   File "/ usr / bin / minimu9-ahrs-calibrator", line 127, in guess     Guess.extend (percentile_to_value (values, 1, 99))   File "/ usr / bin / minimu9-ahrs-calibrator", line 18, in percentile_to_value     Return [list [int (p / 100.0 * (len (list) -1))] for p in percentiles] IndexError: list index out of range "

I am using: MinIMU-9 v3 and Raspberry Pi 3.

Thanks in advance.

Hmm, the segmentation fault is odd. How did you install minimu9-ahrs (e.g. did you compile it from source or use my Debian package)?

Debian package

DavidEGrayson commented 7 years ago

Ok, could you try downloading the latest version of the code from GitHub and compiling it from source? It is possible that something about the shared libraries ha a changed, and it will be easier to diagnose and fix bugs if you can compile it from source.

You would just need to run a couple commands that are listed in the README:

I installed putty on my laptop and ran from there but using: minimu9-ahrs --mode raw -b / dev / i2c-1

And then it came out, then I ran it back on the raspberry and it also came out.

There is an observation: it does not always work well, it often comes out "Segmentation fault (core dumped)

So did you compile it from source like I suggested? If so, we can try using gdb to see what is wrong.
