Detailed Description

External interrupt manager class.

Allows users to handle and manage external interrupts.

Note

For now, only GPIO external interrupts are usable.

Only GPIO interrupts are supported.

Member Function Documentation

init()

static void ecl::exti_manager::init ( )

static

Initializes EXTI manager.

Note

Requires that IRQ manager will be initialized first.

See also

irq_manager

subscribe()

template<typename Gpio >

static void ecl::exti_manager::subscribe ( handler &  h, trigger  t  )

static

Subscribes to event on the given GPIO.

User should retain handler object in the valid state in order to receive any events associated with given EXTI. Upon deletion of the handler object unsubscription will be executed by itself. To start receving events, they must be additionally unmasked via unmask() call.

Precondition

Initialized EXTI manager.

Unused handler.

Warning

If handler was already subscribed to EXTI events then behaviour is undefined.

Postcondition

Handler subscribed for events, but events are masked.

See also

unsubscribe()

unmask()

Parameters

[out]	h	Unsubscribed handler of a GPIO event.
[in]	t	Trigger which will produce event.

unsubscribe()

static void ecl::exti_manager::unsubscribe ( handler &  h )

static

Unsubscribes handler from any event.

Precondition

Initialized EXTI manager.

Previously subscribed handler.

Postcondition

Unsubscribed handler.

It is possible to use the same handler for subscribe() call if it was successfully unsubscribed().

Parameters

[in]

h

Handler, must be previously subscribed.

mask()

static void ecl::exti_manager::mask ( handler &  h )

static

Masks (disables) pending EXTI request.

Precondition

Subscribed handler.

Initialized EXTI manager.

Parameters

[in]

h

Previously subscribed handler.

unmask()

static void ecl::exti_manager::unmask ( handler &  h )

static

Unmasks (enables) pending EXTI request.

Precondition

Subscribed handler.

Initialized EXTI manager.

Parameters

[in]

h

Previously subscribed handler.
