#include <spi.h>

Data Fields
const struct device *	gpio_dev
uint32_t	delay
gpio_pin_t	gpio_pin
gpio_dt_flags_t	gpio_dt_flags

Detailed Description

SPI Chip Select control structure.

This can be used to control a CS line via a GPIO line, instead of using the controller inner CS logic.

Parameters

gpio_dev	is a valid pointer to an actual GPIO device. A NULL pointer can be provided to full inhibit CS control if necessary.
gpio_pin	is a number representing the gpio PIN that will be used to act as a CS line
delay	is a delay in microseconds to wait before starting the transmission and before releasing the CS line
gpio_dt_flags	is the devicetree flags corresponding to how the CS line should be driven. GPIO_ACTIVE_LOW/GPIO_ACTIVE_HIGH should be equivalent to SPI_CS_ACTIVE_HIGH/SPI_CS_ACTIVE_LOW options in struct spi_config.
