SPI end event is not generatinghttps://devzone.nordicsemi.com/f/nordic-q-a/59003/spi-end-event-is-not-generatingDear Sir, To Nordic Dev kit, a sensor is interfaced via SPI lines. Using SPI in blocking mode (Polling). After initializing SPI communication, 2 bytes are written to the sensor. SPI transfer is initiated but does not end, SPI is waiting to get SPIen-USTelligent Community 13Tue, 17 Mar 2020 12:17:10 GMTRE: SPI end event is not generatinghttps://devzone.nordicsemi.com/thread/240246?ContentTypeID=1Tue, 17 Mar 2020 12:17:10 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ff890b73-e57d-4060-9f13-2fa199c1501dLakshmi_K<p>Dear Kenneth,</p> <p>Thank you</p><div style="clear:both;"></div>RE: SPI end event is not generatinghttps://devzone.nordicsemi.com/thread/239885?ContentTypeID=1Mon, 16 Mar 2020 08:07:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:09b23e81-f73c-4758-87e4-6dc78e8d0a2dKenneth<p>I suggest to first verify that the&nbsp;\nRF5_SDK\examples\peripheral\spi works as-is.

Does the same occur if you remove the sensor from the 4 SPI pins in question?</p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>RE: SPI end event is not generatinghttps://devzone.nordicsemi.com/thread/239496?ContentTypeID=1Thu, 12 Mar 2020 10:30:32 GMT137ad170-7792-4731-bb38-c0d22fbe4515:99cf16b2-556b-4df0-b81a-1773a02c6b41Lakshmi_K<p>Dear Kenneth,</p> <p></p> <p>No. But what is the cause for this issue?</p><div style="clear:both;"></div>RE: SPI end event is not generatinghttps://devzone.nordicsemi.com/thread/239477?ContentTypeID=1Thu, 12 Mar 2020 09:41:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:cb47ce95-e831-485a-93c1-23816479b76dKenneth<p>Do you have a logic analyzer trace of CS, CLK, MISO and MOSI?</p> <p>Kenneth</p><div style="clear:both;"></div>
