Function Documentation

void gpio_irq_disable ( gpio_irq_t * obj )

Disable GPIO IRQ.

This is target dependent, as it might disable the entire port or just a pin

Parameters:

obj	The GPIO object

void gpio_irq_enable ( gpio_irq_t * obj )

Enable GPIO IRQ.

This is target dependent, as it might enable the entire port or just a pin

Parameters:

obj	The GPIO object

void gpio_irq_free ( gpio_irq_t * obj )

Release the GPIO IRQ PIN.

Parameters:

obj	The gpio object

Initialize the GPIO IRQ pin.

Parameters:

obj	The GPIO object to initialize
pin	The GPIO pin name
handler	The handler to be attached to GPIO IRQ
id	The object ID (id != 0, 0 is reserved)

Enable/disable pin IRQ event.

Parameters:
