https://devzone.nordicsemi.com/f/nordic-q-a/70052/gpiote-event-in-handler-not-triggeringHello good people at Nordic. Happy new year! I am attempting a simple extension of the GPIOTE example in the SDK. I want to measure the time duration of the generated pulse from the example. In my setup, I have configured two GPIOTE input channelsen-USTelligent Community 13Sat, 09 Jan 2021 18:04:57 GMThttps://devzone.nordicsemi.com/thread/288266?ContentTypeID=1Sat, 09 Jan 2021 18:04:57 GMT137ad170-7792-4731-bb38-c0d22fbe4515:92e74c5d-e90e-4010-a5d5-36887f28add3camsluiter<p>Nevermind! I had mistakenly altered the code posted above. After using the posted code on P0.27, the handler is working. Thanks!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/288265?ContentTypeID=1Sat, 09 Jan 2021 17:21:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b9b6b6d6-9eae-4453-93da-dc48ecbd0725camsluiter<p>Hello J&oslash;rgen,</p> <p></p> <p>Thank you for the reply. Yes, I am using the&nbsp;<span>nRF52840 DK. Thank you for bringing to my attention pin 21 being connected to QSPI. I switched to pin 0.27, which the datasheet says is only GPIO without any&nbsp;additional functionality. Unfortunately, I am not seeing any change (the print statement in the handler isn&#39;t printing). Is there anything else you suggest I modify?&nbsp;</span></p> <p><span>Thank you!</span></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/287181?ContentTypeID=1Mon, 04 Jan 2021 10:33:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:30daf4ce-3894-4fc0-a964-ec094c5f01bfJ&#248;rgen Holmefjord<p>Hi,</p> <p>Are you using nRF52840 DK? By default, P0.21 is connected to the QSPI external flash chip, and not to the pin headers. You need to cute/solder some solder bridges to connect it to the pin headers, see the <a href="https://infocenter.nordicsemi.com/topic/ug_nrf52840_dk/UG/dk/hw_external_memory.html">DK documentation</a>.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
