How to use multiple CAN Channels?

[GarethGZ]

@christoph2, Hello, if I want to do DAQ with multiple ECUs using a multiple-channel CAN interface simultaneously, what's the right way? As I understand, one pyxcp_config.py is for one channel. I didn't find a way to assign the name of the config file without changing the source code. If I need to assign config files, please give me some advice.

Hello,
The name of the configuration can be set via the command-line parameter -c <your-cfg>.py, but I think this was not really your question.
pyXCP works strictly on a one-to-one basis; multiple instances in parallel could be run with the concurrent.interpreters or multiprocessing standard modules.
But the question is, what features are required for communication/synchronization between these instances...
Do you have some good ideas?

Hi, I don't mean these instances to communicate with each other. They only need to work separately. The case can be that on the production line, the test station tests multiple ECUs at the same time. If it is not clear enough, please let me know.

@GarethGZ
OK, I will add a multiprocessing based example.

@christoph2 Thank you for your attention.
