Example for handling button interrupt?

[snowuyl]

I would like to implement button interrupt handler. I found two examples in nRF5 SDK v16.0.0. One is examples\peripheral\pin_change_int. And another one is components\libraries\button\app_button.c. Which one will you suggest?

Hello,

The app_button library is the easiest way to add buttons to your application, and includes things like the debounce implementation.
The pin_change_int demonstrates how you can use a general pin-change as an interrupt.

If you are adding buttons to your application I would recommend making use of the app_button library :)

Best regards,
Karl

Thanks for your support! Do you have suggested example for using app_button library? Besides, do I need to change BUTTON_ENABLED and BUTTON_HIGH_ACCURACY_ENABLED from 0 to 1?

The app_button library is used by all of our ble_peripheral examples, so you could take a look through those to see how you may use it. You can read more about the app button library in its documentation.

This depends on your application. You will need to have enabled the button, but for a regular button press (like a human pressing the button on a Development Kit) you do not need the HIGH_ACCURACY.
