mbl_mw_dataprocessor_sample_create()

METAWEAR_API int32_t mbl_mw_dataprocessor_sample_create	(	MblMwDataSignal *	source,
		uint8_t	bin_size,
		void *	context,
		MblMwFnDataProcessor	processor_created
	)

Create a sample delay processor.

A pointer representing the processor will be passed back to the user via a callback function.

Parameters

source	Data signal providing the input for the processor
bin_size	Number of samples to hold before letting data through
context	Pointer to additional data for the callback function
processor_created	Callback function to be executed when the processor is created

mbl_mw_dataprocessor_sample_modify_bin_size()

METAWEAR_API int32_t mbl_mw_dataprocessor_sample_modify_bin_size	(	MblMwDataProcessor *	sample_delay,
		uint8_t	bin_size
	)

Modify the bin size of a sample delay processor.

Parameters

sample_delay	Sample processor to modify
bin_size	Number of samples to hold before letting data through

Returns

MBL_MW_STATUS_OK if processor configuration was updated, MBL_MW_STATUS_WARNING_INVALID_PROCESSOR_TYPE if a non sample delay processor was passed in
