Detailed Description

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
objThe 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
objThe GPIO object
void gpio_irq_free ( gpio_irq_t obj)

Release the GPIO IRQ PIN.

Parameters
objThe gpio object
int gpio_irq_init ( gpio_irq_t obj,
PinName  pin,
gpio_irq_handler  handler,
uint32_t  id 
)

Initialize the GPIO IRQ pin.

Parameters
objThe GPIO object to initialize
pinThe GPIO pin name
handlerThe handler to be attached to GPIO IRQ
idThe object ID (id != 0, 0 is reserved)
Returns
-1 if pin is NC, 0 otherwise
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.

Returns
PinMap array
void gpio_irq_set ( gpio_irq_t obj,
gpio_irq_event  event,
uint32_t  enable 
)

Enable/disable pin IRQ event.

Parameters
objThe GPIO object
eventThe GPIO IRQ event
enableThe enable flag
