Detailed Description

Function Documentation

init()

void ecl::exti_manager::init ( )

static

Initializes EXTI manager.

Note

Requires that IRQ manager will be initialized first.

Here is the call graph for this function:

unsubscribe()

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

static

Unsubscribes handler from any event.

Precondition

Initialized EXTI manager.

Parameters

[in]

h

Handler, must be previously subscribed.

Here is the call graph for this function:

mask()

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

static

Masks (disables) pending EXTI request.

Parameters

[in]

h

Previously subscribed handler.

unmask()

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

static

Unmasks (enables) pending EXTI request.

Parameters

[in]

h

Previously subscribed handler.

handler()

ecl::exti_manager::handler::handler	(	exti_manager::callback	cb,
		void *	ctx
	)

Constructs handler with user data.

~handler()

ecl::exti_manager::handler::~handler

(

)

Destroys handler and unsubscribe it from EXTI events.

Here is the call graph for this function:

set_cb()

void ecl::exti_manager::handler::set_cb

(

callback

cb

)

Sets user-defined callback.

set_ctx()

void ecl::exti_manager::handler::set_ctx

(

void *

ctx

)

Sets user-defined context.

subscribe()

template<typename Gpio >

void ecl::exti_manager::subscribe ( exti_manager::handler &  h, exti_manager::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.

Precondition

Initialized EXTI manager.

Unused handler.

Warning

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

Parameters

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