Function Documentation

wiced_result_t wiced_deinit_timer

(

wiced_timer_t *

p_timer

)

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

• Parameters

  [in]

  p_timer

  :Pointer to the timer

  Returns

  None

wiced_result_t wiced_init_timer	(	wiced_timer_t *	p_timer,
		wiced_timer_callback_t	p_cb,
		uint32_t	cb_param,
		wiced_timer_type_t	timer_type
	)

Initializes the timer.

Parameters

[in]	p_timer	:Pointer to the timer structure
[in]	p_cb	:Timer callback function to be invoked on timer expiry
[in]	cb_param	:Parameter to be passed to the timer callback function which gets invoked on timer expiry,if any
[in]	timer_type	:Type of the timer

Returns

wiced_result_t

BOOL wiced_is_timer_in_use

(

wiced_timer_t *

p_timer

)

Checks if the 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
	)

Starts the timer Timer should be initialized before starting the timer.

Running the timer interfere with the low power modes of the chip. Time to remain in the low power mode is dependent on the timeout values of the running timers, ie time to sleep is dependent on the time after which the next timer among the active timers expires.

Parameters

[in]	p_timer	:Pointer to the timer structure
[in]	timeout	:Timeout value, in seconds or in milliseconds depending on the timer type

Returns

wiced_result_t

wiced_result_t wiced_stop_timer

(

wiced_timer_t *

p_timer

)

Stops the timer.

• Parameters

  [in]

  p_timer

  :Pointer to the timer structure

  Returns

  wiced_result_t
