I am attempting to do the compass power calibration, and have made a log I want to analyze. I download the script mag_compensation.py from Github, but when I run it I get an error:
File “C:\mag_compensation.py”, line 73
PX4-Autopilot/mag_compensation.py at release/1.13 · PX4/PX4-Autopilot
^
SyntaxError: invalid character ‘·’ (U+00B7)
Am I missing some Python dependencies? I am not able to find out.
Have a look at line 73 in the script. Apparently there is a character there that it doesn’t understand.
Thanks, but that doesn’t make sense. I am using the script just downloaded from Github, so I would expect it should not be wrong
Could it be that you downloaded the html file rather then the raw Python file?
How embarrasing 
Thanks for pointing out the error done by many others.
Now I am starting to get the real challenges. It appears my logs don’t have the same topics as the older logs that this script is based on. Instead of “sensor_mag.00.x”, it uses the format “vehicle_magnetometer.00.magnetometer_ga.00” and so on. I tried changing the topic name and variable names but it appears it doesn’t get the data from the magnetometers (it doesn’t go into the if statements starting at line 116).
I get no error message, but the output is:
←[91m
current-based compensation: ←[0m
param set CAL_MAG_COMP_TYP 2
The the scripts exits.
The same thing happens for thrust-based compensation (except that CAL_MAG_COMP_TYP 1 is stated). I suspect it may have something to do with the variable “timestamp” that I am not able to find in most topics and it appears the script is looking for it, but I am not sure.
