Hello,

Try adding a pullup/pulldown to your GPIOs. I suspect that your gpio is already in the active state.

So if your active state is low, add GPIO_PULL_UP to your init flags:

gpio_pin_configure_dt(&button0, GPIO_INPUT | GPIO_PULL_UP);

See if that helps.

To be sure, you can test this without any changes. If the pin is active low, try shorting the pin to VDD, and then press it again.

Best regards,

Edvin
