https://devzone.nordicsemi.com/f/nordic-q-a/76039/how-can-use-multi-channel-saadc-on-nrf52832Hi everyone, I have a project that needs to use multiple saadc channels but I don&#39;t want to use ppi but use app_timer. So is there any way I can change between saadc channels?en-USTelligent Community 13Mon, 14 Jun 2021 09:16:31 GMThttps://devzone.nordicsemi.com/thread/315055?ContentTypeID=1Mon, 14 Jun 2021 09:16:31 GMT137ad170-7792-4731-bb38-c0d22fbe4515:66817d62-5144-46bf-9551-789b2930c5ffMarjeris Romero<p>Hi,</p> <p>Sorry for the late reply. You need to call <a href="https://infocenter.nordicsemi.com/index.jsp?topic=%2Fsdk_nrf5_v17.0.2%2Fgroup__nrf__drv__saadc.html&amp;anchor=gaf16a16c9de60276dd73cf1811c03ae73">nrf_drv_saadc_sample</a>(). Set multiple channels with <a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/group__nrf__drv__saadc.html?cp=8_1_6_8_0_30_0_4#gad032f5096978d3c3cd1fc8862af31404">nrf_drv_saadc_channel_init()</a> and make sure you have a buffer size with N*enabled_channels with <a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/group__nrf__drv__saadc.html?cp=8_1_6_8_0_30_0_2#ga6df4cb98bb337d1fcd6d8cf7ff0d3670">nrf_drv_saadc_buffer_convert()</a>.<br /><br />For triggering the sampling with nrf_drv_saadc_sample() it&#39;s the same if you use PPI or app timer.</p><div style="clear:both;"></div>
