mbl_mw_dataprocessor_counter_create()

METAWEAR_API int32_t mbl_mw_dataprocessor_counter_create	(	MblMwEvent *	source,
		void *	context,
		MblMwFnDataProcessor	processor_created
	)

Create a counter with an output size of 1 byte.

Counts the number of times an event was fired. A pointer representing the processor will be passed back to the user via a callback function.

Parameters

source	Event the processor is counting
context	Pointer to additional data for the callback function
processor_created	Callback function to be executed when the processor is created

mbl_mw_dataprocessor_counter_create_size()

METAWEAR_API int32_t mbl_mw_dataprocessor_counter_create_size	(	MblMwEvent *	source,
		uint8_t	size,
		void *	context,
		MblMwFnDataProcessor	processor_created
	)

Create a counter with a specific output size.

Counts the number of times an event was fired with a specific output size A pointer representing the processor will be passed back to the user via a callback function.

Parameters

source	Event the processor is counting
size	Output size, between [1, 4] bytes
context	Pointer to additional data for the callback function
processor_created	Callback function to be executed when the processor is created

mbl_mw_dataprocessor_counter_set_state()

METAWEAR_API int32_t mbl_mw_dataprocessor_counter_set_state	(	MblMwDataProcessor *	counter,
		uint32_t	new_count
	)

Overwrites the current count with a new value.

Parameters

counter	Counter processor to modify
new_count	New count value

Returns

MBL_MW_STATUS_OK if processor state was updated, MBL_MW_STATUS_WARNING_INVALID_PROCESSOR_TYPE if a non-counter was passed in
