Getting Noise in data transfer of spihttps://devzone.nordicsemi.com/f/nordic-q-a/60881/getting-noise-in-data-transfer-of-spiI have two nrf52 boards I have dumped spi and spis program in them. When I transfer data from one board to another i get noise For example if i send &quot;123&quot; from master i receive 993 at slave spi master program spi slave programen-USTelligent Community 13Thu, 07 May 2020 12:18:08 GMTRE: Getting Noise in data transfer of spihttps://devzone.nordicsemi.com/thread/248704?ContentTypeID=1Thu, 07 May 2020 12:18:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b4bb9bd3-ff2c-449b-8e0f-b2c01f7572c5Jared<p>Hi,</p> <p>I&#39;ve used a logic analyzer and see that your master application sends the correct data. Using the debugger in SES I also see that the correct data is received by the slave ( See attached image). I&#39;m not sure how you got &quot;993&quot;. Have you checked that the boards are connected correctly?</p> <p><img src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/support-attachments/beef5d1b77644c448dabff31668f3a47-697cdcdcf9d84a0baa6282fbd8a5b9bb/pastedimage1588853883170v1.png" alt=" " /></p><div style="clear:both;"></div>RE: Getting Noise in data transfer of spihttps://devzone.nordicsemi.com/thread/247853?ContentTypeID=1Mon, 04 May 2020 12:12:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:fc3a8804-2e8c-499e-9419-805d2f7d497fhkarthik97<p>Development kt</p><div style="clear:both;"></div>RE: Getting Noise in data transfer of spihttps://devzone.nordicsemi.com/thread/247851?ContentTypeID=1Mon, 04 May 2020 12:11:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:d2a80fd0-7a7b-4403-9795-48066755e928Jared<p>A logic analyzer or Oscilloscope would do the job.
