https://devzone.nordicsemi.com/f/nordic-q-a/47227/saadc-2channels-scan-mode-with-easydmaI need to collect data from 2 ADC channels. Ultimately, the data is to be sent to a table of 1000 samples (500 per channel). Samplerate can be 2KHz - 8kHz. When the table is full, the interrupt should be given. It does not work for me. Here is my codeen-USTelligent Community 13Wed, 15 May 2019 11:15:25 GMThttps://devzone.nordicsemi.com/thread/187203?ContentTypeID=1Wed, 15 May 2019 11:15:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e95ec647-2a52-4c46-b176-7a39e35689c6haakonsh<p>I see that in you previous reply you only enabled channel 0, you need to enable both channels and set RESULT.MAXCNT = (Number of samples * number of channels).&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/187013?ContentTypeID=1Tue, 14 May 2019 14:04:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a7fb194e-5265-4534-979a-2ea335c79635BartoszT<p>But it doesn&#39;t, now it read 128 samples from one channel and inside interrupt channel is changed to another.</p> <p>This is some code from interrupt:</p> <p><img alt=" " height="96" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/DevZone_5F00_INTER2.png" width="220" /></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/186968?ContentTypeID=1Tue, 14 May 2019 12:26:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2e349ed7-8a99-42f9-afcb-75870b5733cdhaakonsh<p>It should give you an interrupt after 64 samples once you&#39;ve enabled the 2. channel (MAXCOUNT/number of channels).&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/186960?ContentTypeID=1Tue, 14 May 2019 12:08:38 GMT137ad170-7792-4731-bb38-c0d22fbe4515:637b0eed-3ab4-4ee5-8ab7-66eb86b2a017BartoszT<p>I changed little and now initialization looks:</p> <p><img alt=" " height="113" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/DevZone_5F00_Ini2.png" width="282" /></p> <p>this gives an interrupt after collecting 128 samples - for one channel only.
