NRF Connect SPIS

[Lewy2552]

Hello, I am trying to convert my codebase from segger embedded studio to nrf connect. I am currently working on the spi section of my codebase.

I am communicating from my STM32U5 (Master) processor and my nrf52840 (slave). I have completed the section on the nordic developer academy where nordic outlines spi. Issue that i am having is that it only shows how to set the nrf as master.

Can I have some assistance on how to set up the device tree in order to put the nrf as as slave, as well as how to grab the DT node properly for communication across that line.

Thanks

Hi

I assume you've been going through the Devicetree overlays section of the lesson here. Did you see the "set device tree overlays" documentation page here and the SPI device bindings reference file here: https://github.com/nrfconnect/sdk-zephyr/blob/b83478a230e79d24d69592274f2a93c9c83958a9/dts/bindings/spi/spi-device.yaml 

Best regards,

Simon

Unfortunately that didnt seem to help too much, but I did find another thread that closely related to this question. The example Helsing provided in the comments helped a ton with this!
