what does zephyr spi_config structure variable slave indicate?

[yogeshiggalore]

Hi all,

struct spi_config {

    uint32_t        frequency;

    uint16_t        operation;

    uint16_t        slave;

    const struct spi_cs_control *cs;

};

in documentation, it says  "@param slave is the slave number from 0 to host controller slave limit." which means number of slaves connected to spi master. 

correct me if my understanding is wrong.

Hi,

 

Zephyr has generic APIs to ensure support for different devices, architectures, and so forth. Not all of the parameters will be used by nRF devices.

In SPI mode, this is not used with our devices. Addressing of slaves is done using a dedicated /CS pin.

 

Kind regards,
