Typedefs
typedef void(*	gpio_pin_callback_t )(void)
	Interrupt callback function type for a GPIO pin. More...

Functions
Interrupt Support
The GPIO can be configured to generate an interrupt when it detects a change on a GPIO pin.
bool	gpio_set_pin_callback (ioport_pin_t pin, gpio_pin_callback_t callback, uint8_t irq_level)
	Set callback for given GPIO pin. More...
static void	gpio_enable_pin_interrupt (ioport_pin_t pin)
	Enable the interrupt of a pin. More...
static void	gpio_disable_pin_interrupt (ioport_pin_t pin)
	Disable the interrupt of a pin. More...
static uint32_t	gpio_get_pin_interrupt_flag (ioport_pin_t pin)
	Get the interrupt flag of a pin. More...
static void	gpio_clear_pin_interrupt_flag (ioport_pin_t pin)
	Clear the interrupt flag of a pin. More...
Peripheral Event System Support
The GPIO can be programmed to output peripheral events whenever an interrupt condition is detected, such as pin value change, or only when a rising or falling edge is detected.
static void	gpio_enable_pin_periph_event (ioport_pin_t pin)
	Enable the peripheral event generation of a pin. More...
static void	gpio_disable_pin_periph_event (ioport_pin_t pin)
	Disable the peripheral event generation of a pin. More...
