https://devzone.nordicsemi.com/f/nordic-q-a/19613/help-spi-readHow can i reaed 32bits word using spi ? I don&#39;t find the function to configure the SPI to read 32bit word ? And how top start reading ? Is this function&quot;uint8_t nrf_spi_rxd_get(NRF_SPI_Type * p_spi);&quot; for reading or for getting the data received onen-USTelligent Community 13Mon, 13 Feb 2017 11:48:44 GMThttps://devzone.nordicsemi.com/thread/76324?ContentTypeID=1Mon, 13 Feb 2017 11:48:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:110461aa-d6da-43d9-ac41-f5929cef4164Ole Bauck<p>You should use the nrf_drv_twi library. Check the examples in the SDK (as Roger commented).</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/76331?ContentTypeID=1Fri, 10 Feb 2017 10:46:43 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0f3b8d49-1e38-4d4f-9b2a-aa1e34118ad9Wojtek<p>Yes Master.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/76330?ContentTypeID=1Fri, 10 Feb 2017 10:44:19 GMT137ad170-7792-4731-bb38-c0d22fbe4515:77b6fb24-8201-4ec0-9383-a32636e16d02ToTo<p>I think i have to use &quot;nrf_spim.h&quot; for my application no ?
