We have a single push button switch for UI purposes. The design is like this. The issue is when the switch is pressed the current draw is much higher. We have a long keyen-USTelligent Community 13Mon, 03 Jul 2023 07:57:24 GMThttps://devzone.nordicsemi.com/thread/434104?ContentTypeID=1Mon, 03 Jul 2023 07:57:24 GMT137ad170-7792-4731-bb38-c0d22fbe4515:7c8bc8ea-49d8-43a4-9b80-064060bc8c79ketiljo<p>Debouncing is easy in FW with a simple timer. Or just use the <span>dk_buttons_and_leds.c</span> as-is as it already has a 10 ms debounce timer built in.&nbsp;</p> <p>I guess that is your problem here, when you disable or enable the pullup when the timer is running.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/434084?ContentTypeID=1Mon, 03 Jul 2023 03:36:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:94b7bdc2-f98c-4e1c-ae61-85c071a99a07kaushalyasat<p>Increasing the 10k and loosing the cap could result in larger noise in switch transitions. Then this has to be filtered by software. This could be one solution, however what I want to know is to understand why the GPIO interrupt seems not working when we dynamically control pull-up.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/433919?ContentTypeID=1Fri, 30 Jun 2023 11:36:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1900dc8f-677d-4a54-b467-f9c08da0cd0cketiljo<p>Can&#39;t you just replace the 10k pull up with a 1M ohm resistors and remove the cap?</p><div style="clear:both;"></div>
