Detecting button sequences

[Chris]

Hi,

nRF51822. I'd like to detect single-click, double-click, triple-click, etc. button press sequences. Multiple clicks are when the next button press is within 1/2second of the previous one.

So, if the button is pressed and released and not pressed again within 1/2second, then I want to do something. But, if it's pressed again within 1/2second, I want to do something else. Etc.

The sequences get even more complicated later on with clicks followed by long presses, but I'd like to first get the multiple-click sequences figured out.

I have button detection working, but am stumped on the best algorithm to use for detecting the multiple clicks.

Thanks for the help.

You best bet is the have an app_timer (SINGLE_SHOT) which starts on the first push and times out at 0.5sec, if the next push is detected before 0.5sec expires you increment a push counter and refresh the 0.5sec timer. Once the 0.5sec timer expires you handle based on how many total pushes were detected in your push counter variable

Hi, can you please assist me, am trying to implement the same code using the Stm8, to detect single, and double press.

STM8 is not a Nordic product!

You need to go to the ST forums for support with that!
