https://devzone.nordicsemi.com/f/nordic-q-a/88382/how-to-use-sense-edge-maskI am registering interrupts for many pins: This only works for the first 8 pins, because from what I understand the GPIOTE peripheral is used and that has only 8 channels. As a solution I found that I should use sense-edge-mask in my device treeen-USTelligent Community 13Mon, 30 May 2022 16:08:46 GMThttps://devzone.nordicsemi.com/thread/370041?ContentTypeID=1Mon, 30 May 2022 16:08:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:483a6ab2-86a3-45c1-9d27-c7e3255cc095J&#248;rgen Holmefjord<p>Hi,</p> <p>You need to configure the GPIOs as inputs as well, see for instance the <a href="https://github.com/nrfconnect/sdk-zephyr/blob/v2.7.99-ncs1-1/samples/boards/bbc_microbit/pong/src/main.c#L497-L500">BBC Micro:bit sample</a>.</p> <p>I tested your code along with the following addition:</p> <p><pre class="ui-code" data-mode="text">gpio_pin_configure(gpio_dev, 13, GPIO_INPUT);</pre></p> <p>I&#39;m then seeing &quot;Pin toggled&quot; when pressing button 0 on the nRF52 DK.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
