hi @christophfroehlich, I would like to work on this issue. I’ve just looked through the codebase of ros2_control_demos and noticed that the realtime_tools package is used in example7, example12, and example14. I believe the task is to update the header files from .h to .hpp. Is that correct?

[christophfroehlich]

Yes, exactly!
