https://devzone.nordicsemi.com/f/nordic-q-a/48564/qdec-doesn-t-sample-fast-signalsHi, I am using mechanical QDEC which doesn&#39;t have LED and simply A and B pins. After going through forum I set the QDEC confguration as follows. Then changed function in nrfx_qdec.c Now I am getting values only if encoder is moving very slowen-USTelligent Community 13Mon, 17 Jun 2019 06:50:54 GMThttps://devzone.nordicsemi.com/thread/193064?ContentTypeID=1Mon, 17 Jun 2019 06:50:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b8ab9d8c-516c-4233-9bbc-c385d4686ef1ovrebekk<p>Hi Ali</p> <p>Good to hear it&#39;s working better <span class="emoticon" data-url="https://devzone.nordicsemi.com/cfs-file/__key/system/emoji/1f642.svg" title="Slight smile">&#x1f642;</span></p> <p>Could you try flipping the input&nbsp;assignments?<br />Then I assume the direction should be inverted.</p> <p>Best regards<br />Torbjørn&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/192976?ContentTypeID=1Fri, 14 Jun 2019 16:04:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b6742543-beea-4836-b7a0-8748557d134fAli Rumane<p><a href="https://devzone.nordicsemi.com/members/ovrebekk">ovrebekk</a>,</p> [quote userid="2116" url="~/f/nordic-q-a/48564/qdec-doesn-t-sample-fast-signals/192943"]reduce the sample period[/quote] <p>Thank you for pointing it out, it is working fine now.</p> <p>Can you please let me know about about direction issue?
