https://devzone.nordicsemi.com/f/nordic-q-a/76254/spis-in-nrf52811-doesn-t-workI&#39;m developing with nRF52811 but firmware is developed for nRF52810. I think there is no difference between them and that firmware should work well. But SPIS doesn&#39;t work well. I followed the guide of migration of infocenter. Is there any mistakeen-USTelligent Community 13Fri, 11 Jun 2021 11:09:20 GMThttps://devzone.nordicsemi.com/thread/314880?ContentTypeID=1Fri, 11 Jun 2021 11:09:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fd6a4614-6ae2-4b3d-af62-a7d9ba14d867JONATHAN LL<p>Hi,&nbsp;<br /><br />Are you using to different PCB, with different pin layout ?&nbsp;<br /><br />They&nbsp;close to the same, and firmware that is developed on on should work on the other.&nbsp;<br /><img src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/811vs810.png" alt=" " /><br /><br />Can you share more details on your setup? If it works on one then it should work on the other.<br /><br />Regards,<br />Jonathan</p><div style="clear:both;"></div>
