Using in embedded systems

[SergeTauger]

I'd like use HFSM2 in firmware for stm32, compiler is GNU ARM Embedded Toolchain (gcc 10.2 or 9.3.1). The problem is that both RTOSes and bare metal usually don't support stdlib and POSIX. Can I use the library as it is or some efforts to port are needed?

Never tried that.
Give it a go!

I cannot get how event dispatching is done. Is that right that std::thread is not used and we should call update() in infinite loop? And I cannot find any usages of mutexes/semaphores in the code, so I have no idea how you implemented event queue. Could you please point me to the code that does dispatching?

std::thread isn't used.
You should call update() in a loop after changeTo<>()
Or just call handleEvent()

There is no event queue, it's outside the scope of an FSM library
So is multithreading support
