GPIOTE Task Handler - Sense Outputhttps://devzone.nordicsemi.com/f/nordic-q-a/4506/gpiote-task-handler---sense-outputHi, I am using TIMER2, GPIOTE and PPI to implement a 6250Hz square wave at a GPIO pin. I can successfully create the square wave on the GPIO pin. However, I would like to be able to sense when this GPIO pin goes high after the GPIOTE peripheral hasen-USTelligent Community 13Wed, 19 Nov 2014 15:23:32 GMTRE: GPIOTE Task Handler - Sense Outputhttps://devzone.nordicsemi.com/thread/15993?ContentTypeID=1Wed, 19 Nov 2014 15:23:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:24d8ef71-955c-4897-90f9-7538c6dc2084Jack<p>OK, thank you very much for your help!</p><div style="clear:both;"></div>RE: GPIOTE Task Handler - Sense Outputhttps://devzone.nordicsemi.com/thread/15992?ContentTypeID=1Wed, 19 Nov 2014 15:21:27 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ff491f1e-f3c0-41d6-911f-bf3de603c7c4Stian R&#248;ed Hafskjold<p>Unfortunately, in order to trigger the interrupt, the pin has to be an input pin and assigned to one of the GPIOTE channels as an IN event. The same pin can not be an output pin and assigned to another GPIOTE channel as an OUT task.</p> <p>However, you can physically wire the GPIO output to another GPIO input, and use this pin to trigger the interrupt.</p><div style="clear:both;"></div>
