canconvert *.arxml *.dbc issue

[Mattas11]

Hi, I try to convert arxml to dbc, but I am getting following error:

C:\Users\DoesNotMatter>canconvert C:\Users\DoesNotMatter\Desktop\canmatrix_test\Any.arxml C:\Users\DoesNotMatter\Desktop\canmatrix_test\Any.dbc xls is not supported INFO - convert - Importing C:\Users\DoesNotMatter\Desktop\canmatrix_test\Any.arxml ...

Another issue I found: When I tried

it converted, but not with the correct Start-Positions/Startbits (see attached pics).

Hi @Mattas11 which version do you use?

At least the first Error was fixed already: https://github.com/ebroecker/canmatrix/commit/97ebe53c66556410d9484f7335c6702f24c19b5f

[Mattas11]

Thanks for response and sry, that I did not find it.

Version I use: Python: 3.10.0 canmatrix: 0.9.5

I will soon try the fixes from your link.

Hi @ebroecker!

With the fix I'm now available to convert .arxml to .dbc, but how can I be sure, that the conversion worked if the sample file I mentioned still does not convert correctly? Also I get the following error message over 300 times (not in the sample file): "ERROR - arxml - No valid compu method found for isignal/systemsignal [signalname] - check ARXML file!!"?

Thanks and best regards!

@Mattas11

I am unsure, something works now something doesn't work at your side?

The Error you mention (No valie compu method) is more a warning. This may lead to uncorrect scaling.

However, if you can provide some example, I'll able to do more support...
