Function Documentation

TimerGetCurrentTime()

TimerTime_t TimerGetCurrentTime

(

void

)

Read the current time.

Returns

current time

TimerGetElapsedTime()

TimerTime_t TimerGetElapsedTime

(

TimerTime_t

time

)

Return the time elapsed since a fix moment in Time.

Parameters

[in]

time

fix moment in Time

Returns

elapsed time

TimerGetFutureTime()

TimerTime_t TimerGetFutureTime

(

TimerTime_t

time

)

Return the time elapsed since a fix moment in time.

Parameters

[in]

time

fix moment in the future

Returns

difference between now and future event

TimerInit()

void TimerInit	(	TimerEvent_t *	obj,
		void(*)(void)	callback
	)

Initializes the timer object.

Remarks

TimerSetValue function must be called before starting the timer. this function initializes timestamp and reload value at 0.

Parameters

[in]	obj	Structure containing the timer object parameters
[in]	callback	Function callback called at the end of the timeout

TimerReset()

void TimerReset

(

TimerEvent_t *

obj

)

Resets the timer object.

Parameters

[in]

obj

Structure containing the timer object parameters

TimerSetValue()

void TimerSetValue	(	TimerEvent_t *	obj,
		uint32_t	value
	)

Set timer new timeout value.

Parameters

[in]	obj	Structure containing the timer object parameters
[in]	value	New timer timeout value

TimerStart()

void TimerStart

(

TimerEvent_t *

obj

)

Starts and adds the timer object to the list of timer events.

Parameters

[in]

obj

Structure containing the timer object parameters

TimerStop()

void TimerStop

(

TimerEvent_t *

obj

)

Stops and removes the timer object from the list of timer events.

Parameters

[in]

obj

Structure containing the timer object parameters
