uint16_t pal_generate_rand_seed ( void )

Generation of random seed for function srand() in case this is not supported by the transceiver (e.g.

AT86RF230)

Returns: uint16_t Random number to be used as seed for function srand()

void pal_get_current_time ( uint32_t * current_time )

Gets current time.

This function returns the current time.

Parameters

[out] current_time Returns current system time

bool pal_is_timer_running ( uint8_t timer_id )

Checks if the timer of requested timer identifier is running.

This function checks if the timer of requested timer identifier is running.

Parameters

timer_id Timer identifier

Returns

true if timer with requested timer id is running,
false otherwise.

	)

Starts high priority timer.

This function starts a high priority timer for the specified timeout.

Parameters

timer_id	Timer identifier
timer_count	Timeout in microseconds
timer_cb	Callback handler invoked upon timer expiry
param_cb	Argument for the callback handler

Returns

PAL_TMR_INVALID_ID if the identifier is undefined,
MAC_INVALID_PARAMETER if the callback function for this timer is NULL,
PAL_TMR_ALREADY_RUNNING if the timer is already running, or
MAC_SUCCESS if timer is started successfully.

retval_t pal_stop_high_priority_timer ( uint8_t timer_id )

Stops a high priority timer.

This function stops a high priority timer.

Parameters

timer_id Timer identifier

Returns

PAL_TMR_NOT_RUNNING if the timer id does not match with the high priority timer register, or
MAC_SUCCESS otherwise.

void pal_task ( void )

Services timer and sio handler.

This function calls sio & timer handling functions.

retval_t pal_timer_get_id ( uint8_t * timer_id )

retval_t pal_timer_start	(	uint8_t	timer_id,

		timeout_type_t	timeout_type,
		FUNC_PTR	timer_cb,
		void *	param_cb
	)

Start regular timer.

This function starts a regular timer and installs the corresponding callback function handle the timeout event.

Parameters

timer_count	Timeout in microseconds
timeout_type	TIMEOUT_RELATIVE or TIMEOUT_ABSOLUTE
timer_cb	Callback handler invoked upon timer expiry
param_cb	Argument for the callback handler

Returns

PAL_TMR_INVALID_ID if the timer identifier is undefined,
MAC_INVALID_PARAMETER if the callback function for this timer is NULL,
PAL_TMR_ALREADY_RUNNING if the timer is already running.
MAC_SUCCESS if timer is started or
PAL_TMR_INVALID_TIMEOUT if timeout is not within timeout range.

retval_t pal_timer_stop ( uint8_t timer_id )

Stops a running timer.

This function stops a running timer with specified timer_id

Parameters

timer_id Timer identifier

Returns

MAC_SUCCESS if timer stopped successfully,
PAL_TMR_NOT_RUNNING if specified timer is not running,
PAL_TMR_INVALID_ID if the specifed timer id is undefined.
