https://devzone.nordicsemi.com/f/nordic-q-a/83120/spi-sub-node-configuration-using-nrfx-spimI finally had success in getting a SPIM master running with a single SPI slave (Honeywell sensor running CS 4 on the Arduino R3 header) on my nRF9160DK. But now I need to add a second SPI slave device (a Crystalfontz LCD) and I need to control the CSen-USTelligent Community 13Mon, 27 Dec 2021 11:06:20 GMThttps://devzone.nordicsemi.com/thread/345089?ContentTypeID=1Mon, 27 Dec 2021 11:06:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8427e292-7e21-4aa2-85c9-3dea5792d24bH&#229;kon Alseth<p>Hi,</p> <p>&nbsp;</p> <p>To declare more than one cs-gpios, you should define it similar to this:</p> <p><a href="https://github.com/nrfconnect/sdk-nrf/blob/v1.8.0/boards/arm/thingy91_nrf9160/thingy91_nrf9160_common.dts#L134">https://github.com/nrfconnect/sdk-nrf/blob/v1.8.0/boards/arm/thingy91_nrf9160/thingy91_nrf9160_common.dts#L134</a></p> <p>&nbsp;</p> <p>And you want to fetch index 1 via this call instead:</p> <p><a href="https://github.com/nrfconnect/sdk-zephyr/blob/v2.7.0-ncs1/include/devicetree/gpio.h#L93">https://github.com/nrfconnect/sdk-zephyr/blob/v2.7.0-ncs1/include/devicetree/gpio.h#L93</a></p> <p></p> <p>This is because the macro that you use at this moment always assumes index 0:</p> <p><a href="https://github.com/nrfconnect/sdk-zephyr/blob/v2.7.0-ncs1/include/devicetree/gpio.h#L113-L114">https://github.com/nrfconnect/sdk-zephyr/blob/v2.7.0-ncs1/include/devicetree/gpio.h#L113-L114</a></p> <p></p> <p>Kind regards,</p> <p>Håkon</p><div style="clear:both;"></div>
