Detailed Description

Defines the interfaces for Timer Management Services.

Macro Definition Documentation

#define wiced_timer_target_time_get

(

p_target_timer

)

(((p_target_timer))->tt)

Get the expected trigger point (time) of target timer.

Parameters

[in]

p_target_timer

: pointer to the target timer control block

Returns

a 64-bit value time in microsecond.

Typedef Documentation

typedef void( wiced_timer_callback_t)(TIMER_PARAM_TYPE cb_params)

Function prototype for the timer call back.

Parameters

[in]

cb_params

:Timer callback function

typedef struct _wiced_timer_t wiced_timer_t

Timer structure.

NOTE: this structure is used internally by the wiced stack. Applications MUST NOT modify any of the elements of this structure.

Timer control block memory MUST be peristant from when the timer is initialized, using wiced_init_timer(), till it is de-initialized, using wiced_deinit_timer().

Enumeration Type Documentation

enum wiced_timer_type_e

Defines the wiced timer types.

These timers are system tick driven and a systick is 1 millisecond.So the minimum timer resolution supported is 1 millisecond

Function Documentation

wiced_result_t wiced_deinit_timer

(

wiced_timer_t *

p_timer

)

Deinitialize a timer instance and stops the timer if it is running.

Parameters

[in]

p_timer

:Pointer to the timer

Returns

wiced_result_t

wiced_result_t wiced_init_timer	(	wiced_timer_t *	p_timer,
		wiced_timer_callback_t *	p_timer_cb,
		TIMER_PARAM_TYPE	cb_arg,
		wiced_timer_type_e	timer_type
	)

Initializes the timer.

Parameters

[in]	p_timer	:Pointer to the timer structure
[in]	p_timer_cb	:Timer callback function to be invoked on timer expiry
[in]	cb_arg	:Parameter to be passed to the timer callback function which gets invoked on timer expiry,if any
[in]	timer_type	:Shows if the timer is milliseconds or seconds, and if periodic or not

Returns

wiced_result_t

wiced_bool_t wiced_is_timer_in_use

(

wiced_timer_t *

p_timer

)

Checks if a timer is in use.

Parameters

[in]

p_timer

:Pointer to the timer structure

Returns

0 if the timer is not in use and non-zero value if the timer is in use

wiced_result_t wiced_start_timer	(	wiced_timer_t *	p_timer,
		uint32_t	timeout_ms
	)

Starts a timer.

Parameters

[in]	p_timer	:Pointer to the timer structure
[in]	timeout_ms	:timeout in milliseconds

Returns

wiced_result_t

wiced_result_t wiced_stop_timer

(

wiced_timer_t *

p_timer

)

Stops a timer.

Parameters

[in]

p_timer

:Pointer to the timer structure

Returns

wiced_result_t
