Function Documentation

void adaptive_sync_calculateCompensatedSlots

(

int16_t

timeCorrection

)

Calculate the compensation interval, in number of slots.

Parameters

[in]

timeCorrection

time to be corrected

Returns

compensationSlots the number of slots.

void adaptive_sync_countCompensationTimeout

(

void

)

update compensationTimeout at the beginning of each slot and adjust current slot length when the elapsed slots rearch to compensation interval.

Once compensationTimeout == 0, extend or shorten current slot length for one tick.

void adaptive_sync_countCompensationTimeout_compoundSlots

(

uint16_t

compoundSlots

)

update compensationTimeout when compound slots are scheduled and adjust the slot when the elapsed slots rearch to compensation interval(e.g. SERIALRX slots)

Parameters

[in]

compoundSlots

how many slots will be elapsed before wakeup next time.

void adaptive_sync_driftChanged

(

void

)

set driftChanged to true.

void adaptive_sync_init

(

void

)

initial this module

void adaptive_sync_preprocess	(	int16_t	timeCorrection,
		open_addr_t	timesource
	)

Calculated how many slots have elapsed since last synchronized.

Parameters

[in]	timeCorrection	time to be corrected
[in]	timesource	The address of neighbor.

Returns

the number of slots
