spi_cs_control Struct Reference

SPI Chip Select control structure. More...

#include <spi.h>

Data Fields

struct gpio_dt_spec gpio
 GPIO devicetree specification of CS GPIO.
 
uint32_t delay
 Delay in microseconds to wait before starting the transmission and before releasing the CS line.
 

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.

Field Documentation

◆ delay

uint32_t spi_cs_control::delay

Delay in microseconds to wait before starting the transmission and before releasing the CS line.

◆ gpio

struct gpio_dt_spec spi_cs_control::gpio

GPIO devicetree specification of CS GPIO.

The device pointer can be set to NULL to fully inhibit CS control if necessary. The GPIO flags GPIO_ACTIVE_LOW/GPIO_ACTIVE_HIGH should be equivalent to SPI_CS_ACTIVE_HIGH/SPI_CS_ACTIVE_LOW options in struct spi_config.
