https://devzone.nordicsemi.com/f/nordic-q-a/13006/spi-configurationHi, I&#39;m trying to configure the SPI by using the nrf_drv_spi. the problem that I&#39;m facing is the configuration of the &quot;spi_config.SPI_CPHA = SPI_CONFIG_CPHA_Leading&quot; which exict in the &quot;spi_master.h&quot; &amp; not in the &quot;nrf_drv_spi.h&quot;. what should i doen-USTelligent Community 13Wed, 06 Apr 2016 09:20:56 GMThttps://devzone.nordicsemi.com/thread/49576?ContentTypeID=1Wed, 06 Apr 2016 09:20:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:4ba11342-272d-4471-a369-626058a2b88bbjorn-spockeli<p>This is specified by the by the <code>nrf_drv_spi_mode_t</code> field in the the <code>nrf_drv_spi_config_t</code> struct. The SPI peripheral can be set up in the following 4 modes:</p> <pre><code>NRF_DRV_SPI_MODE_0 - SCK active high, sample on leading edge of clock. NRF_DRV_SPI_MODE_1 - SCK active high, sample on trailing edge of clock. NRF_DRV_SPI_MODE_2 - SCK active low, sample on leading edge of clock. NRF_DRV_SPI_MODE_3 - SCK active low, sample on trailing edge of clock. </code></pre> <p>Please refer the SPI Master documentation on our Infocenter, found <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v11.0.0/hardware_driver_spi_master.html?cp=4_0_0_2_12">here</a>.
