I use photon. I would like to use the simplest multithreading task operation (not timer). Because my delay() operations are stopping the flow of the program. For example; Void simple_function () { DigitalWrite (D1, HIGH); Delay (5,000); DigitalWrite (D1, LOW); } I want to handle this function…

Yes i tried and tried it. But I can not undo the RAM I am using. This consumes the RAM after several uses and the device is locked. Do I need another way or should I be able to reclaim the used ram?

@pusent , threads cannot be destroyed on Particle devices. You should be using an Software Timers or a non-blocking FSM (finite state machine) in loop() to implement your controls.

I understood thank you. I try to find another way.

@pusent , don’t hesitate to ask for assistance:wink:

Well, how the simplest case, the FSM?

@pusent , if you use a software Timer set for 1 second “ticks” that will be the basis for your timed GPIO transition. You simply need to have a flag to indicate a start of sequence which will be looked at in the timer callback. Something like this: #define WAIT 0 #define ON 1 #define OFF 2 …

Owww… nice example for me. thanks alot

yeah that’s a good example. thank you @peekay123
