https://devzone.nordicsemi.com/f/nordic-q-a/70130/nrf9160-low-power-edge-interruptDear All, We are currently developing a low power application for the nRF9160, with ncs zephyr version 1.2.0. For our application we want to trigger an interrupt on both the rising and falling edge. We use the GPIO_INT, GPIO_INT_EDGE, GPIO_INT_DOUBLE_EDGEen-USTelligent Community 13Wed, 06 Jan 2021 09:30:08 GMThttps://devzone.nordicsemi.com/thread/287654?ContentTypeID=1Wed, 06 Jan 2021 09:30:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5ebffd4d-d42e-47fc-a832-afc62f3b4e8eMaaike<p>Thank you for the information.<br /><br />Kind regards,<br />Maaike</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/287634?ContentTypeID=1Wed, 06 Jan 2021 08:02:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:824dc7ba-2594-4171-a02b-3fc20e9f8a8bH&#229;kon Alseth<p>Hi,</p> <p>&nbsp;</p> <p>GPIO_INT*_EDGE will enable the use of a GPIOTE IN channel (code reference here: <a href="https://github.com/nrfconnect/sdk-zephyr/blob/master/drivers/gpio/gpio_nrfx.c#L110">https://github.com/nrfconnect/sdk-zephyr/blob/master/drivers/gpio/gpio_nrfx.c#L110</a>), compared to using GPIO SENSE and the GPIOTE PORT event.</p> <p>GPIO SENSE can do level triggering, while edge-triggering can only be done by GPIOTE IN channel, which does add ~30 uA in sleep (this number depends on which nRF-device is used).</p> <p>&nbsp;</p> <p>Kind regards,</p> <p>Håkon</p><div style="clear:both;"></div>
