Typedef Documentation

gpio_sipomux_config_t

typedef struct gpio_sipomux_config gpio_sipomux_config_t

#include <drivers/gpio/gpio_sipomux.c>

SIPO/MUX GPIO controller configuration data.

This structure contains all of the state for a given SIPO/MUX GPIO controller as well as all of the pins associated with it.

num_pins must be in the range [1, GPIO_MAX_PINS_PER_PORT].

num_offs must be in the range [1, SIPO/MUX GP maximum minus num_pins].

Pin direction as well as other pin properties are set using specific bits in flags. For more details, see gpio_interface.

gpio_sipomux_data_t

typedef struct gpio_sipomux_data gpio_sipomux_data_t

#include <drivers/gpio/gpio_sipomux.c>

SIPO/MUX GPIO controller data.

This structure contains data structures used by a SIPO/MUX GPIO controller.

Changes are to gpio_sipomux_data and gpio_sipomux_config are synchronized using k_sem.
