KConfig for nRF52DK

[morerook]

Hello,

I am trying to use the NCS with the nRF52DK and I'm trying to use the SPI.

This is my prj.conf file

CONFIG_SPI=y
CONFIG_SPI_0=y

And this is my .overlay file

&spi0 {
    status = "ok";
    compatible = "nordic,nrf-spi";
    sck-pin = <10>;
    mosi-pin = <11>;
    miso-pin = <12>;
};

However, when I compile it with `west build -p auto` I run into this error: 

warning: attempt to assign the value 'y' to the undefined symbol SPI_0

How can I properly set up and use SPI on nRF52DK? Thanks for the advice.

I'm also having issues with getting SPI to work - even using the default examples, when I compile for the nRF52DK, I don't get any signal out of the spi0 or spi1 devices and any pins. No SCK signal.

I didn't zoom in far enough in my logic analyser -.-

Usually, logic analyzer software allows you to set a trigger. I would recommend that you set a edge-trigger on either the CSN or the CLK pin.

 With newer version of ncs, the instance is enabled from device tree (ie. no need to manually enable, especially when its the first instance).

 

Kind regards,
