Re: low level CAN service question

Hi,

This part of the documentation has been taken from OpenXC documentation but as specified not well tested here and as to be taken as is... As far as I know, I think it has been deprecated and not maintained anymore. So a new one should be developed not relying on upstream OpenXC. Reusing the code without bringing the whole OpenXC development environment.

I'd be on it, anyway I can't do it right now but for start I'd need a XML sample file, it would simplify a bit the thing for me. I'll take a look at it soon and let you know.

Best regards.

Regarding CAN bus I'm having an issue generating a signals.json file from a signals.xml file. Following the instructions in the link below I created a signals.xml file from my DBC file using Vector's CANdb++ then created a mapping.json file.

 

http://docs.automotivelinux.org/docs/apis_services/en/dev/reference/signaling/low-level-can-service-guide.html#generating-json-from-vector-canoe-database

 

The following is not working for me:

 

python -m openxc.utils ./xml_to_json.py signals.xml mapping.json signals.json

 

The above appears to do nothing other than load the modules then exit.

 

I've been able to manually create my own signals.json file taking a single message from the XML file then went on to create application-generated.cpp, built low-can-service, installed it and verified it can handle the new message.

 

Any insight would be appreciated. 

 

Thanks,
Dave
