https://devzone.nordicsemi.com/f/nordic-q-a/30286/nrf52832-spi-dummy-clock-cycles-after-tx-sdk-v14-2-0Hi, I am using the nRF52832 on a custom PCB and I am interfacing it with a flash memory chip through SPI. I am testing the SPI communication using the spi example (nRF52 SDK 14.2.0\examples\peripheral\spi). Using an oscilloscope I can see that eachen-USTelligent Community 13Wed, 07 Feb 2018 13:14:26 GMThttps://devzone.nordicsemi.com/thread/120113?ContentTypeID=1Wed, 07 Feb 2018 13:14:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8f631685-a18a-451a-ae2b-9e560220691bLorenzo<p>Thank you very much</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/120112?ContentTypeID=1Wed, 07 Feb 2018 13:10:28 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a21eadfb-9656-4edb-9c46-c3c5b8d17f00RK<p>Err&nbsp; - your&nbsp; tx buffer is an&nbsp; array of ints, so they are each 4 bytes long little endian. So you&#39;re asking for 4x2 = 8&nbsp; bytes to be clocked out and so you get all 4 bytes of each integer, the top 3 of which are zero in your case. If you want to clock out 2 bytes, use uint8_t not&nbsp; int.&nbsp;&nbsp;</p> <p>You&nbsp; are getting exactly what you programmed.&nbsp;</p><div style="clear:both;"></div>
