Hi Anika,
OpenXC is a lot of the things. The VI, Android Library, Python library, etc. From your question, it sounds like you want to use the openxc-python library on Linux to talk to another device connected to CAN. If so, then no, that won't really work. The Python is expecting to talk to a device that is running vi-firmware (i.e. one of our VIs).
Regards,
Eric
