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

union { ... } spi_cs_control::@117

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.

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_dev

const struct device* spi_cs_control::gpio_dev

gpio_dt_flags

gpio_dt_flags_t spi_cs_control::gpio_dt_flags

gpio_pin

gpio_pin_t spi_cs_control::gpio_pin
