Hi, All

How better to process the button usage with MCU (esp32 family, if more detailed) - if task is to control complex button clicking ?
Short click, long click, double-click, triple-click...

Say,
1) single short click - to wake MCU up
2) Next short clicks - for listing the work modes
3) long click - some setup
4) After some pause the single short click - deepsleeping.

Any lib for such button usage ?

Use a timer after wake-up... button down -> timer on if time passed is bigger than x time, then its a long press... button up -> another timer to way for second click if timer1 is off or long = false

No such lib, but a module could be easily built for this fonction

What I am thinking is how does a short click is different than the bouncing in terms of time duration. Once you can answer this I believe you are close to all solutions.

Click to expand...

Actually, now thinking about it, there is no difference. At the first bounce you define it was clicked and then if it is a long click after bouncing period it will still be clicked.

You set a minimal timer1 duration so that button down is true, then on button up set Timer1 off, and start timer 2 to detect second click
