Detailed Description

Function Documentation

nfc_scheduler_init()

void nfc_scheduler_init	(	nfc_scheduler_t *	pScheduler,
		nfc_scheduler_timer_t *	pTimer
	)

Init scheduler.

Parameters

pScheduler	scheduler instance to init
pTimer	timer instance

nfc_scheduler_iteration()

uint32_t nfc_scheduler_iteration	(	nfc_scheduler_t *	pScheduler,
		uint32_t	events
	)

Iterate through all tasks.

Parameters

pScheduler	scheduler instance
events	mask of events (except EVENT_TIMEOUT) that have been raised since this function last returned (0 on first call)

Returns

time after which this function must be called again if no other event arises

nfc_scheduler_queue_task()

void nfc_scheduler_queue_task	(	nfc_scheduler_t *	pScheduler,
		nfc_task_t *	pTask
	)

Queue a task to execute.

Parameters

pScheduler	scheduler instance
pTask	task to queue

nfc_scheduler_dequeue_task()

void nfc_scheduler_dequeue_task	(	nfc_scheduler_t *	pScheduler,
		bool	abort,
		nfc_task_t *	pTask
	)

Remove a task to execute.

Parameters

pScheduler	scheduler instance
pTask	task to remove
abort	abort task if queued

task_init()

		uint32_t	events,
		uint32_t	timeout,
		nfc_task_fn	fn,
		void *	pUserData
	)

Initialize task with the following parameters.

Parameters

pTask	task to initialize
events	events on which to call task
timeout	if relevant
fn	function to be called
pUserData	data that will be passed to function
