Hi Basem,

Based on what I noted previously, can you:

1) test upto four buttons using only the DK Button library,

2) test upto four button using only your own configuration and not the DK button library,

3) if it is working correctly (step 1 and 2), then extend for more buttons

OK but why the described issue happens, and how can I prevent it?

Yes, the DK Button and LED library is designed to work with up to 4 LEDS and 4 Buttons only.

Hi Naeem,

Thank you for your response, and actually I'm using Matter: Template sample to create my matter light bulb device, and this sample uses the DK button and LED library, where I used zephyr GPIO.h, I just didn't modify what the sample uses.

The behavior I got is strange and I can't understand its reason.

I can't use the DK button and LED library because I think it can't provide more than 4 LEDs and 4 buttons, and I need to control 10 buttons and around 10 LEDs.

Regards,

Basem

Hi Basem,

Why are you using the DK button and LED library when you are configuring the pin yourself?

you can achieve what you want to do by just configuring the pin as you are doing and not using the DK button lib, or just by using the DK button lib. Below I am just using the DK button library and removed pin interrupt config from the main. I can see clock cycles when the button is pressed and released:

(showing short, short and long button press).
