https://devzone.nordicsemi.com/f/nordic-q-a/13214/spi-master-with-s130-softdevice-sdk11-nrf51I am having difficulties porting the SPI Master demo to an S130 Soft Device on SDK 11.0.0. From the looks of it, there seem to be some issues with interrupts but I am unsure of exactly what is going on. Several posts on here specify that with SDK 10en-USTelligent Community 13Wed, 15 Jun 2016 23:19:10 GMThttps://devzone.nordicsemi.com/thread/50388?ContentTypeID=1Wed, 15 Jun 2016 23:19:10 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c41c20e7-85e0-4de4-9416-30bf24e2f963senses<p>I should ask using nrf_drv_spi.h with MODE2, I am seeing the clock lagging data by quite a few clock cycles. any clues? <img src="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/nrf_5F00_drv_5F00_spi_5F00_transfer1.png" alt="image description" /></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/50387?ContentTypeID=1Tue, 19 Apr 2016 11:25:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5711b725-0eb9-4391-9be7-ec288d0980b0bjorn-spockeli<p>Yes, the SPI driver ( <code>nrf_drv_spi.c</code> ) in SDK v10.00 is independent of the SoftDevice, so there should be no issues using this in an application that uses a SoftDevice.</p> <p>I am afraid that the only examples on how to use the SPI Master driver are without a SoftDevice. However, if you could describe the issue a bit more in detail and I&#39;ll try to see if I can help you.</p> <p>Yes, they are two separate drivers. The spi_w5_master driver is a 5-Wire SPI driver that is used by the PHY layer in our BLE serialization library, i.e when the nRF51 is used as a connectivity chip and communincates with a host processor.</p> <p>-Bjørn</p><div style="clear:both;"></div>
