# 1.1.4.21 DRV_METROLOGY_GetHarData Function

## C

    DRV_METROLOGY_REGS_HARMONICS * DRV_METROLOGY_GetHarData (void);

## Summary

Get the pointer to the harmonic analysis registers of the metrology library application running on the second processor.

## Description

Harmonic analysis registers are acting as 32-bit metrology harmonic analysis registers. The Metrology module shall generate the following primary output measurement quantities for each measurement interval, per-phase quantities with each phase designated by the subscript “_x” (where x = [A, B, C or D] for voltage channels and x = [A, B, C or N] for current channels). Internal scaling allows accurate harmonic analysis for integration periods of up to 16 seconds for up to full-scale magnitude input waveforms. For a detailed description of the harmonic analysis registers, refer to the `drv_metrology_regs.h` header file.

## Parameters

None.

## Returns

Pointer to the 32-bit metrology harmonic analysis registers.

## Example

        /* Get Pointers to metrology data regions */
        app_metrologyData.pMetControl = DRV_METROLOGY_GetControlData();
        app_metrologyData.pMetStatus = DRV_METROLOGY_GetStatusData();
        app_metrologyData.pMetAccData = DRV_METROLOGY_GetAccData();
        app_metrologyData.pMetHarData = DRV_METROLOGY_GetHarData();

## Remarks

None.
