https://devzone.nordicsemi.com/f/nordic-q-a/125183/does-spi-frame-length-support-32-bitMy SPI slave sensor requires a 32-bit frame length. The CS (Chip Select) signal needs to be switched for each 32-bit frame interval, and it also supports DMA (Direct Memory Access) transmission. Does the nRF5340 or nRF52840 support this?en-USTelligent Community 13Fri, 24 Oct 2025 05:07:30 GMThttps://devzone.nordicsemi.com/thread/552310?ContentTypeID=1Fri, 24 Oct 2025 05:07:30 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5bbf63fe-e519-4f45-b9ce-4ecf58daaf5fvalerian123<p>Thank you. We are going to give it a try.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/552284?ContentTypeID=1Thu, 23 Oct 2025 15:02:29 GMT137ad170-7792-4731-bb38-c0d22fbe4515:116d7bf0-f472-4352-a070-c0ea6a91b7d4Susheel Nuguru<p>Hi Xiao, all of our products are working with with fixed 8-bit SPI frames.<br /> For 32-bit sensors, use 4-byte transfers and toggle CS per frame through GPIOTE/PPI control. We dont have a template code to show this but a lot of other users have achieved this using GPIOTE/PPI combo to toggle CS if you set 4-byte transfers (MAXCNT = 4)</p><div style="clear:both;"></div>
