https://devzone.nordicsemi.com/f/nordic-q-a/28085/nrf51422-gpiote-with-pushbuttonHi, I am building a custom PCB using the nRF51422 chip. I need to include a pushbutton switch on the PCB to generate an interrupt when it is pressed(gpiote). I am connecting the pushbutton switch to an analogue pin. For the pushbutton, should I connecten-USTelligent Community 13Fri, 15 Dec 2017 07:33:28 GMThttps://devzone.nordicsemi.com/thread/110686?ContentTypeID=1Fri, 15 Dec 2017 07:33:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5979ce33-6424-431d-83bb-d24e720d1d89Aurabindo<p>nevermind, found the api for this</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/110685?ContentTypeID=1Fri, 15 Dec 2017 07:28:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5a3de7cc-639c-4dcf-9cd5-c051d86666bcAurabindo<p>@Sigurd Can I still enable internal pull up and also use it with GPIOTE to generate interrupts ?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/110684?ContentTypeID=1Wed, 12 Jul 2017 11:51:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:748c0593-e524-42b9-af63-03a012e0e397Sigurd<p>Hi,</p> <p>Pushbuttons are usually active low, meaning the input will be connected to ground when the button is activated (pushed). So you connect one side of the button to the nRF-pin you want to use, and the other side to ground. You don’t need any external pull-up/down resistor, just configure the nRF-pin as input with active internal pull-up.</p> <p><img src="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/6747.button.png" alt="image description" /></p><div style="clear:both;"></div>
