But when trying to configure with nrf52dk board (nrf52832 IC , pca10040), and read the device ID iten-USTelligent Community 13Mon, 27 Sep 2021 13:24:48 GMThttps://devzone.nordicsemi.com/thread/331330?ContentTypeID=1Mon, 27 Sep 2021 13:24:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:efa08fad-c486-46f3-97f3-518132419181Jared<p>Hi,</p> [quote user=""]<p><span>The scope&nbsp;image when trying to send the command 0x9f is as shown below.&nbsp;</span></p> <p><span><img alt=" " src="https://devzone.nordicsemi.com/resized-image/__size/320x240/__key/communityserver-discussions-components-files/4/1854.IMG_2D00_20210924_2D00_WA0003.jpg" style="cursor:zoom-in;" /></span></p>[/quote] <p>If blue is MOSI and yellow is SCLK then it seems like it sending the correct command&nbsp;<span>0b10011111?
