https://devzone.nordicsemi.com/f/nordic-q-a/19347/nrf52-gpio-usageHi. I&#39;m trying to figure out how to properly use GPIO pins, but so far I did not find a document explaining how to use GPIO with nrf included functions. I found bits and pieces of code which use GPIO but that is no documentation.

There is many threads about GPIO usage here on DevZone, for instance <a href="https://devzone.nordicsemi.com/question/111451/gpio-configuration-code/">here</a>.</p> <p>You address the pins by the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/pin.html?cp=2_2_0_3#pin_assign">pin number of the port</a>, so P0.00 is adressed 0, P0.01 is 1 and so on.</p> <p>Best regards,</p> <p>Jørgen</p><div style="clear:both;"></div>
