How to delay power on/off (e.g，hold on 3 seconds)https://devzone.nordicsemi.com/f/nordic-q-a/58543/how-to-delay-power-on-off-e-g-hold-on-3-secondsHi all, I&#39;m developing a board based on nRF52832. I want to implement delay power on and power off through holding a single power button for about 3 seconds. Regarding hardware design, I will connect battery DC-out pin to a GPIO pin directly. en-USTelligent Community 13Mon, 02 Mar 2020 09:01:30 GMTRE: How to delay power on/off (e.g，hold on 3 seconds)https://devzone.nordicsemi.com/thread/237338?ContentTypeID=1Mon, 02 Mar 2020 09:01:30 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8a3803af-1d3e-4320-b222-ab04309e0e36cbd<p>You&#39;ll need to power the processor in order to perform this in software.</p> <p>If that is the case then you should have the processor control the power to the rest of the board using another GPIO line and suitable circuitry.</p> <p>Just run a timer, start it on your button pressed GPIO line transition and check its value on the button release transition if the timer has run for 3 seconds or more then switch the power to the rest of the board.</p><div style="clear:both;"></div>
