https://devzone.nordicsemi.com/f/nordic-q-a/30468/spi-interface-with-sd-cardHello all, Do you advise to have 2 SPI interfaces - one for the sensors we&#39;re using (accelero/ gyro) and another one for the SD card? if so, when adding an SD card to our board we have to change pins, is that correct? thanks for your quck answersen-USTelligent Community 13Tue, 13 Feb 2018 09:54:58 GMThttps://devzone.nordicsemi.com/thread/120690?ContentTypeID=1Tue, 13 Feb 2018 09:54:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e1c5b968-21ab-465a-90d6-bfe03452631eJakub Rzeszutko<p>It depends. If you do not need to have transfers at the same time you can use only one SPI instance.</p> <p>When using one instance you also have a choice. If you wish to save some GPIOs both slaves can share MOSI, MISO and CLK lines and only have sparate PINs for SS.</p> <p>You can take a closer look to nrf_spi_mngr (<a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v14.2.0/lib_nrf_spi_mngr.html?cp=4_0_0_3_44">http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v14.2.0/lib_nrf_spi_mngr.html?cp=4_0_0_3_44</a>) functionality, it allows to schedule transfers with different PIN configuration.</p><div style="clear:both;"></div>
