https://devzone.nordicsemi.com/f/nordic-q-a/40503/put-external-connected-ads1220-chip-into-continuous-data-read-modeI am trying to read analog voltage using NRF dev board through an external connected ADC (ADS1220), not the internal saadc. My DK board is nrf52, PCA10040. I start with the SPI (master) example which reads data from the ADC in one-shot default mode justen-USTelligent Community 13Thu, 15 Nov 2018 21:01:01 GMThttps://devzone.nordicsemi.com/thread/157597?ContentTypeID=1Thu, 15 Nov 2018 21:01:01 GMT137ad170-7792-4731-bb38-c0d22fbe4515:3dbadf23-473e-4db8-940e-d4ed8bf9b42fKenneth<p>Hi,</p> <p>You do not write the SPI configuration you are using, but typically you need wait for the&nbsp;SPI event handler that indicate transfer is finish before you can execute next SPI transaction. Also I suggest to add some error checks on the SPI transfer calls you are doing if you are not already.</p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>
