How to use SPI_DT_GET_SPEC macro properly?

[Meh]

Hello, Devzone community :)

I'm trying to use the SPI_DT_GET_SPEC without success. I have constant 3 errors:

 error: 'DT_N_S_soc_S_spi_4002f000_S_foo_0_P_duplex' undeclared here (not in a function); did you mean 'DT_N_S_soc_S_spi_4002f000_S_foo_0_P_label'?
  error: 'DT_N_S_soc_S_spi_4002f000_S_foo_0_P_spi_max_frequency' undeclared here (not in a function); did you mean 'DT_N_S_soc_S_spi_4002f000_S_foo_0_P_compatible_LEN'?
   error: 'DT_N_S_soc_S_spi_4002f000_S_foo_0_P_frame_format' undeclared here (not in a function); did you mean 'DT_N_S_soc_S_spi_4002f000_S_foo_0_P_reg_IDX_0'?

My initialization on the main file:

#define SPI3_NODE DT_NODELABEL(foo)
static const struct spi_dt_spec dev_spi = SPI_DT_SPEC_GET(SPI3_NODE, SPI_WORD_SET(8) | SPI_MODE_GET(0), 0);

My overlay:

    &spi3 {
            foo: foo@0{
                compatible = "spi-device";
                reg = <0>;
                spi-max-frequency = < DT_FREQ_M(8) >;
                label = "FOO";
                
        };
    };

Seems like it should work at first glance. I would check to make sure the "compatible" dts binding is set up correctly and is being found. Should just need to have

include: spi-device.yaml

It's well-bondednordicator_prim3

Hi

For us to help you with this in the best possible way, please list the following information:

• SDK Version
• Development Kit Version
• Which sample do you use, if any?

Also, what is your end goal with "dev_spi"?

Regards,
Sigurd Hellesvik

Apologies!

NCS V2.2.0

nRF52840 (DK)/ nRF5340 (DK)

Not using any samples, my prj.cfg is CONFIG_SPI=y, CONFIG_I2C=y, CONFIG_LOG=y.

End goal: using it in initializing SPI sensor and read from it

A colleague of mine has made an NCS-SPI-Master-Slave-Example.

Look at this and see if you can figure out how to use the devicetree from this.

Let me know if you have any questions afterwards.
