ARDUINO_13_PIN is set to P0.25 (Digital pin 13) on the DK.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/267574?ContentTypeID=1Wed, 02 Sep 2020 09:22:24 GMT137ad170-7792-4731-bb38-c0d22fbe4515:79847a18-b231-43a8-bbcc-ace30221d0f2Sherwood<p>Thank you for the reply in the case of the following&nbsp;</p> <pre>.sck_pin = ARDUINO_13_PIN<br /><br />is the sck pin connected to p0.13?</pre><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/267545?ContentTypeID=1Wed, 02 Sep 2020 07:45:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c8d2f317-bfc1-4fcf-bc5c-31201b3cd9ccSimonr<p>Hi</p> <p>You can see what pins the SPI uses in the init_spi0_master() function in the example project. You can also edit these configs to use the pins you&#39;d like.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
