https://devzone.nordicsemi.com/f/nordic-q-a/24870/nrf52832---how-to-merge-ant-and-peripheral-examplesHello, I&#39;m developing firmware for a custom PCB with an nRF52832 chip. I&#39;ve implemented almost all of the peripheral functionality I need (including TWI, GPIO, GPIOTE, delay, power, and SAADC) via the &quot;template_project&quot; example. I&#39;ve also implementeden-USTelligent Community 13Wed, 06 Sep 2017 15:06:28 GMThttps://devzone.nordicsemi.com/thread/97953?ContentTypeID=1Wed, 06 Sep 2017 15:06:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4c2059de-d157-46df-b026-a5bd067988ffPetter Myhre<p>Great that you figured it out :) And that you shared the solution :)</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/97952?ContentTypeID=1Tue, 05 Sep 2017 21:55:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8d44193d-4882-4d82-a30b-1e870e1bb97bDGraham<p>The issue was a compiler setting. I was using the P0.09 as an output GPIO, however this is default set as a pin for the NFC peripheral. In order to use it as a GPIO pin (and thus quit throwing an error when I tried to interact with it like a GPIO), you need to add the &quot;CONFIG_NFCT_PINS_AS_GPIOS&quot; to the preprocessor definitions for the project.</p> <p>After solving this I was able to incorporate the GPIO, GPIOTE, SAADC, and TWI peripherals with no issue.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/97951?ContentTypeID=1Tue, 05 Sep 2017 16:53:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:008e6b61-0034-4b4a-9799-1e11df911e98DGraham<p>I&#39;m going to go in today and add each peripheral one by one, starting with the GPIO, and see where the issue starts to pop up.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/97950?ContentTypeID=1Tue, 05 Sep 2017 11:39:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a81f3433-902c-46c5-a60e-dc95a1a002abPetter Myhre<p>I&#39;m not sure what is going on. Is this behavior reproducible if this GPIO code is added to a simple ANT example?</p><div style="clear:both;"></div>
