https://devzone.nordicsemi.com/f/nordic-q-a/87092/no-response-after-configuring-qdec-peripheralHello! I am struggling to configure a quadratic encoder with the nRF52840. As far as I know, the code should be working. However, when the encoder rotating, the terminal says zephyr is rebooting. I am thinking this means the system has crashed or somethingen-USTelligent Community 13Wed, 20 Apr 2022 13:09:56 GMThttps://devzone.nordicsemi.com/thread/363952?ContentTypeID=1Wed, 20 Apr 2022 13:09:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b047cb3d-227a-4bc0-8c96-20f8438b1749Kenneth<p>It looks like you are using the nrfx api directly, in that case you also need to define the interrupt handler by using the IRQ_CONNECT() as shown for instance in this example using nrfx gpiote: <a href="https://github.com/nrfconnect/sdk-zephyr/blob/main/samples/boards/nrf/nrfx/src/main.c#L35">https://github.com/nrfconnect/sdk-zephyr/blob/main/samples/boards/nrf/nrfx/src/main.c#L35</a>&nbsp;</p> <p>Another example using nrfx is found here:<br /><a href="https://devzone.nordicsemi.com/f/nordic-q-a/71737/lpcomp-in-ncs-zephyr-on-nrf52/">https://devzone.nordicsemi.com/f/nordic-q-a/71737/lpcomp-in-ncs-zephyr-on-nrf52/</a>&nbsp;</p> <p>Kenneth</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/363701?ContentTypeID=1Tue, 19 Apr 2022 17:51:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c29baaee-6396-4304-8685-b78dd3b06415Faws<p>Some additional information, this is the error that comes up after checking the error message:</p> <p><img alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/563x154/__key/communityserver-discussions-components-files/4/Error_5F00_qdec.jpg" /></p><div style="clear:both;"></div>
