Usage instructions for arduino-fsm lib?

I need a state machine lib capable of implementing states, state exit callbacks, state transition callbacks and state enter callbacks. The library arduino-fsm seemed to be suitable. However I was not able to get "in state" callback functions working properly. Has anyone used the lib already and can help?

I don't recall the last time I saw questions about any state machine library here and I know that multiple people have written them.

Add to that, the fact that the population of members here that answer questions is quite small and I suspect that the pool of people that can answer your question is tiny or zero.

I would suggest that if you know you're going to need help, you're better off writing your own state machine using the classic switch case method. Plenty of people here can assist you with that.

I understand. Thanks for the hint.
