Function Documentation

◆ 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.

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

Parameters
sourceEvent the processor is counting
contextPointer to additional data for the callback function
processor_createdCallback 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.

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

Parameters
sourceEvent the processor is counting
sizeOutput size, between [1, 4] bytes
contextPointer to additional data for the callback function
processor_createdCallback 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
counterCounter processor to modify
new_countNew 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
