Need some clarification on function nrf_gpio_cfg_outputhttps://devzone.nordicsemi.com/f/nordic-q-a/87211/need-some-clarification-on-function-nrf_gpio_cfg_outputI am not sure what I am missing in this. This is a custom board so there is no other circuitry on this pin other than a pad to monitor the signal changes with. When my main function calls the init code above, I go and look at the pin and only seeen-USTelligent Community 13Mon, 25 Apr 2022 08:18:12 GMTRE: Need some clarification on function nrf_gpio_cfg_outputhttps://devzone.nordicsemi.com/thread/364628?ContentTypeID=1Mon, 25 Apr 2022 08:18:12 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0b14c32b-d4b4-413d-a502-5c51a96703deEinarh<p>How to do this is described&nbsp;<a href="https://infocenter.nordicsemi.com/index.jsp?topic=%2Fug_nrf52832_dk%2FUG%2Fnrf52_DK%2Fhw_nfc.html&amp;cp=4_2_4_5_10">here.</a></p><div style="clear:both;"></div>RE: Need some clarification on function nrf_gpio_cfg_outputhttps://devzone.nordicsemi.com/thread/364525?ContentTypeID=1Fri, 22 Apr 2022 15:40:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:dead2fab-fd40-49c0-825b-be1495ab9407AllenS<p>Actually I did by debugging step by step in the code.</p><div style="clear:both;"></div>RE: Need some clarification on function nrf_gpio_cfg_outputhttps://devzone.nordicsemi.com/thread/364524?ContentTypeID=1Fri, 22 Apr 2022 15:39:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:11806a96-1955-4c20-8da5-4d3578dba756AllenS<p>Where is this define located?&nbsp; I checked sdk_config.h and nrf_gpio.h and was not able to find it.&nbsp; Any suggestions?</p><div style="clear:both;"></div>RE: Need some clarification on function nrf_gpio_cfg_outputhttps://devzone.nordicsemi.com/thread/364405?ContentTypeID=1Fri, 22 Apr 2022 08:59:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:37ad84cf-502c-436a-825b-0759e6a80fc9mrono<p>Pin 0.09 is one of the NFC pins. You need to explicitly enable the GPIO function on that pin.
