Detecting Interruption Sense on Both stateshttps://devzone.nordicsemi.com/f/nordic-q-a/5287/detecting-interruption-sense-on-both-statesHi everyone !! I have this hardware mapping, and I&#39;d like to detect pin state change with an interrupt. My problem is that it seems I can&#39;t configure an interruption with sense on both edge. As you can see, my switch can either set 0 or 1 toen-USTelligent Community 13Wed, 28 Jan 2015 11:53:37 GMTRE: Detecting Interruption Sense on Both stateshttps://devzone.nordicsemi.com/thread/18497?ContentTypeID=1Wed, 28 Jan 2015 11:53:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:50755ebe-bffb-4393-ab66-92dc79deb28bEnero<p>Thank you guys, It&#39;s working well now !!!</p> <p>Have a good day, and thanks for your help.</p> <p>Hugo.B</p><div style="clear:both;"></div>RE: Detecting Interruption Sense on Both stateshttps://devzone.nordicsemi.com/thread/18498?ContentTypeID=1Wed, 28 Jan 2015 11:50:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5a36ec53-3115-4f57-97be-5ab2a8cd4cf2Asbj&#248;rn<p>Agree with MattB here. There are gpio events available in the SDK. <a href="http://developer.nordicsemi.com/nRF51_SDK/doc/7.2.0/s110/html/a00757.html#ga5c8310a3b7a81cc4a267844c81769a40">nrf_gpio_pin_toggle()</a></p><div style="clear:both;"></div>RE: Detecting Interruption Sense on Both stateshttps://devzone.nordicsemi.com/thread/18496?ContentTypeID=1Mon, 26 Jan 2015 15:42:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:49df3146-5a73-4c45-8a0c-04ec6fe4939eMatt Barr<p>Refer to GPIO tasks and events (GPIOTE) in the nRF51 Series Reference Manual. The CONFIG[n] POLARITY field has LoToHi, HiToLo and Toggle. You should be able to specify Toggle and enable an interrupt on the related IN[n] event (any change on pin).</p><div style="clear:both;"></div>
