I am trying to set up an interrupt for a GPIO I call the createInterrupt() function on the main() to configure, initialize and enable the interrupten-USTelligent Community 13Thu, 20 Aug 2020 13:35:46 GMThttps://devzone.nordicsemi.com/thread/265572?ContentTypeID=1Thu, 20 Aug 2020 13:35:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ad35ef85-db07-4e86-931a-08ab12d6d964Nikosant03<p>Hi Einar,</p> <p>I have defined WC_CHG like this</p> <p><pre class="ui-code" data-mode="c_cpp">#define WC_CHG 46 // na - Monitor WPT (Wireless Power Transfer) - 0: wireless charging ON , 1: wireless charging OFF</pre></p> <p>Ok, using a different GPIO it works fine..

And you are right, you should measure the VDD voltage on the input pin after enabling the pull-up if it is unconnected. You do not write how you have defined&nbsp;WC_CHG, other than that it is&nbsp;P1.14, so I want to mention that you should define it like this to make sure you get it mapped correctly (to 32+14=46).</p> <p><pre class="ui-code" data-mode="c_cpp">#define WC_CHG NRF_GPIO_PIN_MAP(1,14)</pre></p> <p>Does that work?</p> <p>Einar</p><div style="clear:both;"></div>
