You set the pins in the <a href="http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v14.2.0%2Fstructnrf__drv__spi__config__t.html">config struct</a> passed to the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v14.2.0/group__nrf__drv__spi.html#ga2319de449c320ce104d8f3b40759c64c">SPI driver init function</a>. The pin&nbsp;assignments can be found in the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/pin.html?cp=2_1_0_3#pin_assign">documentation</a>.</p> <p>Best regards,<br />Jørgen</p><div style="clear:both;"></div>
