SPI slave peripheral receive interrupt processinghttps://devzone.nordicsemi.com/f/nordic-q-a/16488/spi-slave-peripheral-receive-interrupt-processingSPI Slave configuration On nRF52 Hi, I am trying to configure the SPI slave peripheral for interrupt based communicaton with a SPI master In previous work with ARM based chips, the typical sequence I have followed would be : configureen-USTelligent Community 13Mon, 19 Sep 2016 13:21:09 GMTRE: SPI slave peripheral receive interrupt processinghttps://devzone.nordicsemi.com/thread/63116?ContentTypeID=1Mon, 19 Sep 2016 13:21:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ff70e5ed-62ee-4885-9cd2-674357a89e59Ole Bauck<p>First of all you should use SDK 12 (link to infocenter is for SDK 0.9.2, which is old and not production release version).</p> <p>The event handler is called when the transaction is done (CSN goes high after valid transaction) or when the buffers are configured (semaphore is released -&gt; SPIS peripheral is ready for transaction). There is no way to get event when CS goes low. See the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/spis.html?cp=2_2_0_31_2#concept_abk_lbf_wr">Product Specification</a> for the SPIS peripheral.</p> <p>I did not quite understand what you aim to do and why you are uncertain if the SPIS driver from the SDK can be used.</p><div style="clear:both;"></div>
