/usr/lib/python3/dist-packages/revpimodio2/modio.py RuntimeWarning: can not execute all event functions in one cycle - optimize your event functions or rise .cycletime RuntimeWarning

Hi johnruk4670!

That will happen, if your event function takes more time than the internal cycle time. If you register an event function it must be executed within a cycle, otherwise the functions will overlap.

Example: You push a button, the function will start work, take 1 second. In that second you pushed the button 3 times more, so the same function will be queued 3 times and will be executed one after one. So it will take 4 seconds to execute the same function 4 times, without any other Input-Action.

You can call the functions asynchronous by adding as_thread=True in the .reg_event call.
