https://devzone.nordicsemi.com/f/nordic-q-a/20808/nrf52832-can-detect-signal-be-edge-detectHi all, I am thinking of using a GPIO pin&#39;s &quot;SENSE LOW&quot; to wake up my device from SYSTEM OFF mode. In order to avoid the device keeps waking up in case the pin stays low (e.g. a button is continuously pushed), I would like to use the DETECT signalen-USTelligent Community 13Mon, 27 Mar 2017 12:48:21 GMThttps://devzone.nordicsemi.com/thread/81273?ContentTypeID=1Mon, 27 Mar 2017 12:48:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ea941a50-76ee-43b6-a3b6-3ad65269372fElnath0412<p>Hi Sigurd,</p> <p>Thank you very much for your answer. I tried it and it looks like your advice certainly works. :)</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/81272?ContentTypeID=1Mon, 27 Mar 2017 12:39:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:03e94f17-67f0-4033-afe1-a69640cdf0acSigurd<p>Hi,</p> <p>Q: Is there a way to make the signal be edge detect, or is there any code recipe to achieve something similar?</p> <p>A: Yes, you can use the ANADETECT signal. The <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/lpcomp.html?cp=2_2_0_38#concept_tdv_zkx_lr">LPCOMP</a> can wake up the system from <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/power.html?cp=2_2_0_17_1#unique_1884019601">System OFF</a> by asserting the ANADETECT signal. The ANADETECT signal can be derived from any of the event sources that generate the UP, DOWN and CROSS events. Take a look at the <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v13.0.0/lpcomp_example.html?cp=4_0_0_4_4_14">LPCOMP Example</a> in the SDK for how to configure and use the LPCOMP.</p><div style="clear:both;"></div>
