gpio_callback Struct Reference

GPIO callback structure. More...

#include <gpio.h>

Data Fields
sys_snode_t	node
	This is meant to be used in the driver and the user should not mess with it (see drivers/gpio/gpio_utils.h)
gpio_callback_handler_t	handler
	Actual callback function being called when relevant.
gpio_port_pins_t	pin_mask
	A mask of pins the callback is interested in, if 0 the callback will never be called.

Detailed Description

GPIO callback structure.

Used to register a callback in the driver instance callback list. As many callbacks as needed can be added as long as each of them are unique pointers of struct gpio_callback. Beware such structure should not be allocated on stack.

Note: To help setting it, see gpio_init_callback() below

Field Documentation

handler

gpio_callback_handler_t gpio_callback::handler

Actual callback function being called when relevant.

node

sys_snode_t gpio_callback::node

This is meant to be used in the driver and the user should not mess with it (see drivers/gpio/gpio_utils.h)

pin_mask

gpio_port_pins_t gpio_callback::pin_mask

A mask of pins the callback is interested in, if 0 the callback will never be called.

Such pin_mask can be modified whenever necessary by the owner, and thus will affect the handler being called or not. The selected pins must be configured to trigger an interrupt.
