https://devzone.nordicsemi.com/f/nordic-q-a/22509/spi-missing-interruptsI am using NRF51422 S130. I have a master SPI configuration set up, and not using Nordic spi drivers provided in the examples. I think my configuration is correct. 1- I send one byte of data at 2Mbips clock rate and can see on scope the 8 clock bitsen-USTelligent Community 13Fri, 02 Jun 2017 12:28:22 GMThttps://devzone.nordicsemi.com/thread/88563?ContentTypeID=1Fri, 02 Jun 2017 12:28:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:45f13600-233e-4294-91fe-2b2ce3461688Jay S.<p>I found the solution. Although the nrfF51 spec does not explicitly explains this but in order to get a new interrupt you need to read every input received by SPI in addition to clear READY register. I simply added {rdata = NRF_SPI1-&gt;RXD;} in the IRQ service call and I am getting every READY IRQ.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/88561?ContentTypeID=1Fri, 02 Jun 2017 08:33:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:67e3e72a-9978-4707-b5c4-9f5113d4ce01J&#248;rgen Holmefjord<p>Can you post/upload your code and possibly a logic trace of the SPI bus?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/88562?ContentTypeID=1Fri, 02 Jun 2017 00:26:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ed50ea09-05f4-493c-9d35-00c93a0973d4Wojtek<p>Something is wrong.</p><div style="clear:both;"></div>
