https://devzone.nordicsemi.com/f/nordic-q-a/74356/nrf5340---zephyr-dma-adc-exampleI am working with the nRF5340 DK. I am looking to sample an ADC pin to sample at a sampling frequency of at least 1kHz and I would like to use DMA to write the data directly to memory while freeing the CPU. I tried reading the nRFConnect SDK anden-USTelligent Community 13Mon, 20 Dec 2021 22:02:23 GMThttps://devzone.nordicsemi.com/thread/344450?ContentTypeID=1Mon, 20 Dec 2021 22:02:23 GMT137ad170-7792-4731-bb38-c0d22fbe4515:87daa53c-97f9-4579-b265-76d4b2597c24whati001<p>Sorry for the down vote, but I am currently facing the same problem and the answer does not help much if somebody tries to get started with the entire nrf ecosystem.</p> <p>This question helped me a lot: <a href="https://devzone.nordicsemi.com/f/nordic-q-a/78191/simple-example-adc-for-nrf5340-pdk">https://devzone.nordicsemi.com/f/nordic-q-a/78191/simple-example-adc-for-nrf5340-pdk</a></p> <p>It links to some sample code: <a href="https://github.com/crfosse/ncs_projects/tree/main/peripheral_zephyr/adc">https://github.com/crfosse/ncs_projects/tree/main/peripheral_zephyr/adc</a></p> <p>The code seems to sample port P0.04 (A0).</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/306717?ContentTypeID=1Mon, 26 Apr 2021 08:49:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0a17d748-452c-4687-b517-623f83ab4431Marjeris Romero<p>Hi,</p> <p>SAADC in nRF53 always uses EasyDMA: <a title="https://infocenter.nordicsemi.com/topic/ps_nrf5340/saadc.html?cp=3_0_0_6_28_5#saadc_easydma" href="https://infocenter.nordicsemi.com/topic/ps_nrf5340/saadc.html?cp=3_0_0_6_28_5#saadc_easydma" rel="noopener noreferrer" target="_blank">https://infocenter.nordicsemi.com/topic/ps_nrf5340/saadc.html?cp=3_0_0_6_28_5#saadc_easydma</a></p> <p>So there is no need to configure EasyDMA specifically for SAADC.<br /><br /></p> <p>Best regards,</p> <p>Marjeris</p><div style="clear:both;"></div>
