Enumeration Type Documentation

MblMwPassthroughMode

enum MblMwPassthroughMode

Operation modes for the processor.

Enumerator
MBL_MW_PASSTHROUGH_MODE_ALL	Allow all data through.
MBL_MW_PASSTHROUGH_MODE_CONDITIONAL	Only allow data through if count > 0.
MBL_MW_PASSTHROUGH_MODE_COUNT	Only allow a fixed number of data samples through.

Function Documentation

mbl_mw_dataprocessor_passthrough_create()

METAWEAR_API int32_t mbl_mw_dataprocessor_passthrough_create	(	MblMwDataSignal *	source,
		MblMwPassthroughMode	mode,
		uint16_t	count,
		void *	context,
		MblMwFnDataProcessor	processor_created
	)

Create a passthrough 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
mode	Processor's operation mode
count	Internal count to initial the processor with
context	Pointer to additional data for the callback function
processor_created	Callback function to be executed when the processor is created

mbl_mw_dataprocessor_passthrough_modify()

METAWEAR_API int32_t mbl_mw_dataprocessor_passthrough_modify	(	MblMwDataProcessor *	passthrough,
		MblMwPassthroughMode	mode,
		uint16_t	count
	)

Modify the passthrough configuration.

Parameters

passthrough	Passthrough processor to update
mode	New operation mode to use
count	New initial count

Returns

MBL_MW_STATUS_OK if processor configuration was updated, MBL_MW_STATUS_WARNING_INVALID_PROCESSOR_TYPE if a non-passthrough processor was passed in

mbl_mw_dataprocessor_passthrough_set_count()

METAWEAR_API int32_t mbl_mw_dataprocessor_passthrough_set_count	(	MblMwDataProcessor *	passthrough,
		uint16_t	new_count
	)

Modify the internal count of the passthrough processor.

Parameters

passthrough	Passthrough processor to modify
new_count	New internal count

Returns

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