Doesn't load config file when launched from a startup script about python-can HOT 5 CLOSED

Original comment by Travis Travelstead (Bitbucket: travis_travelstead, GitHub: Unknown):

Hello,

Let me see if I can help.

the "/ect/" folder is used during boot, but I also have the config file in "/root/" for when I am testing the files after the system is already booted. So if you are waiting for the system to boot and then you are executing the files yourself, I would suggest to put then in "/root/" or whatever user you currently are logged in as.

Hope that helps

Hi,

I am working on can interface with python-can and I've the same problem that Travis :

raise ImportError("CAN interface not found")

I put my can.conf file in /ect

I work with python2.7 and i'm root.
When I test my interface with candump or CanSend function. can0 interface works

Why python-can fonction doesn't detect my can interface ?

thanks

No worries. Please submit further issues as they come up. Contributions are welcome if you think the documentation could be clearer too!

Brian, you have been amazing with the support of your product.

This solves my immediate problem. I do thing the option to use the config would be nice over being required.

Thanks again!

If you are planning to use as both a non privileged user and as root I would put the config in your global configuration directory /etc/can.conf.

It is also possible to use environment variables as well, see can/util.py
