Detailed Description

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
context	The context to be passed back to the handler (context != 0, 0 is reserved)

const PinMap* gpio_irq_pinmap ( void )

Get the pins that support all GPIO IRQ tests.

Return a PinMap array of pins that support GPIO IRQ. The array is terminated with {NC, NC, 0}.

Targets should override the weak implementation of this function to provide the actual pinmap for GPIO IRQ testing.

Enable/disable pin IRQ event.
