https://devzone.nordicsemi.com/f/nordic-q-a/117750/using-zephyr-spi-driver-with-generic-deviceI need to connect a device to an nRF5340 SPI port without creating a custom driver. I&#39;m tempted to use the nrfx_spim driver directly, but I&#39;m trying to do it with Zephyr and the device tree. I&#39;ve looked for examples of how to use the Zephyr SPI driveren-USTelligent Community 13Tue, 07 Jan 2025 05:33:26 GMThttps://devzone.nordicsemi.com/thread/517118?ContentTypeID=1Tue, 07 Jan 2025 05:33:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f167e57d-5e24-4437-bc90-4e58e8589df8Saxman58<p>I&#39;m embarrassed to say that part of the problem was that I had the logic analyzer set for 3.3V logic, not realizing that the nRF7002 board uses 1.8V!<br /><br />But in the mean time I have switched over to using the nrfx_spim library instead, and have made good progress with it.&nbsp; I feel SO much more comfortable working more directly with the lower level drivers and hardware than the Zephyr abstractions, after a few years of working with the nRF5 SDK.<br /><br />So there is no need to answer this original ticket, and feel free to delete it.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/517087?ContentTypeID=1Mon, 06 Jan 2025 19:30:15 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0c23f6b3-bb5a-43ae-ac8d-e82a9479fcddSaxman58<p>I know that the SPI4 port is unusual, so I tried the same code with the SPI1 port at 8 MHz.&nbsp; Same results:&nbsp; The SCK, MOSI and MISO pins are stuck at ground, and the CS# pin seems to be floating (noise on the logic analyzer).</p><div style="clear:both;"></div>
