https://devzone.nordicsemi.com/f/nordic-q-a/22377/nrf52-s123-qdec-sample-period---sdk-12-2-0I am developing an application which involves control of a brushed DC motor with a quadrature encoder. According to this post, in SDK 12.2.0 - which I am using - it is possible to set the sample period to 128 us rather than the 512 us minimum reporteden-USTelligent Community 13Tue, 20 Jun 2017 18:01:56 GMThttps://devzone.nordicsemi.com/thread/87989?ContentTypeID=1Tue, 20 Jun 2017 18:01:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4c1c4c56-7308-4e98-974d-a09c19681482Nick Bentzen<p>Hi Kristin - that was the problem.

What should it be sent to? I don&#39;t actually need an LED for this device, I was just using it to help visualize what the encoder is doing with my scope.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/87986?ContentTypeID=1Mon, 29 May 2017 11:26:47 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f21de43f-152c-4cd9-9c73-3b1727ccaf35FormerMember<p>In SDK 12.2.0, the QDEC example problem should have been fixed. To which value is QDEC_CONFIG_LEDPRE set to?</p><div style="clear:both;"></div>
