SPI CS Example not working

[Menealano]

Following the example from the link below, I tried to specify the CS Pin in the .c source file

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/zephyr/hardware/peripherals/spi.html#c.SPI_CS_CONTROL_PTR_DT

#include <zephyr/drivers/gpio.h>                                                                                                                                                    

#include <zephyr/drivers/spi.h>

struct spi_cs_control *cs_ctrl_f7 =

        &(struct spi_cs_control) {

                .gpio_dev = DEVICE_DT_GET(DT_NODELABEL(gpio1)),

                .delay = 2,

                .gpio_pin = 6,

                .gpio_dt_flags = GPIO_ACTIVE_LOW

        };

/* SPI-Mode 0 (CPOL Low, CPHA Low) required for STM32F769 SPI bootloader, f_max= 8 MHz */

static const struct spi_config spi_cfg_f7 = {

    .operation = SPI_WORD_SET(8) | SPI_TRANSFER_MSB,

    .frequency = 4000000,

    .slave = 0,

    .cs = &cs_ctrl_f7

};

But this results in Errors like the following: error: 'struct spi_cs_control' has no member named 'gpio_pin'

Could you please provide an example of how to use multiple SPI CS-Pins specified in a C source file?

Hi, 

You can have a look at this unofficial example https://github.com/too1/ncs-spi-master-slave-example  created by one of the Nordic Employees.
