PCAN Explorer 7 Callbacks using Python

Post by Shepdog » Thu 19. Feb 2026, 18:05

Are there plans to support python scripts being used as callbacks?

The documentation states callbacks are handled using DLLs.

We already have several custom python modules developed when working outside of PCAN Explorer 7. For example, one script will analyze data bytes of a message and then insert the checksum before it is sent.

We would really benefit if we didn't have to rewrite our python scripts into another language to compile them as DLLS.

I am open to other suggestions of how to implement our custom Python code within PCAN Explorer 7.

Hello,

Thanks for sharing your suggestion.

We understand your need, but unfortunately we cannot offer this for technical reasons. Calls to python scripts mean a big overhead for the CAN communication and performance lost.
Best regards,
Keneth
