Function Documentation

◆ 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
sourceData signal providing the input for the processor
bin_sizeNumber of samples to hold before letting data through
contextPointer to additional data for the callback function
processor_createdCallback 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_delaySample processor to modify
bin_sizeNumber 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
