https://devzone.nordicsemi.com/f/nordic-q-a/25114/gpio-vs-gpiote-usageHi everyone, I am developing a remote control using nRF52832 chip. My prototype is currently developed in PC10040 board. The IDE is Eclipse Oxygen, and the SDK is S132 v5.0.0. In my system, there are LED indicators, user buttons and a wake-up buttonen-USTelligent Community 13Tue, 12 Sep 2017 16:49:12 GMThttps://devzone.nordicsemi.com/thread/98904?ContentTypeID=1Tue, 12 Sep 2017 16:49:12 GMT137ad170-7792-4731-bb38-c0d22fbe4515:df05d204-1b25-43a6-9f45-77ddcf145956huaminhtuan<p>Thanks endnode :D</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/98903?ContentTypeID=1Tue, 12 Sep 2017 16:39:35 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b9feaa51-9532-4b6e-877b-61030864238aendnode<p>Basically YES.
