voltage	Pointer to the variable which will hold the converted voltage

Return Value

Error code or 0.

Usage Example

    ERRPARAMS errparams;
    DSCDASETTINGS dasettings;
    DSCB dscb;
    DSCDACODE dacode;
    DFLOAT voltage;
    BYTE result;

    /* Board initialization code omitted */

    dasettings.polarity = BIPOLAR;
    dasettings.load_cal = TRUE;
    dasettings.range = 10.0;

    if ((result = dscDAConvert(dscb, 0, dacode)) != DE_NONE)
    {
        dscGetLastError(&errparams);
        fprintf(stderr, "dscDAConvert failed: %s (%s)\n", 
                dscGetErrorString(result), errparams.errstring);
        return result;
    }

    if ((result = dscDACodeToVoltage(dscb, dasettings, dacode, &voltage)) != DE_NONE)
    {
        dscGetLastError(&errparams);
        fprintf(stderr, "dscDACodeToVoltage failed: %s (%s)\n", 
                dscGetErrorString(result), errparams.errstring);
        return result;
    }

   printf("DA code converted: %d, Actual voltage: %5.3lfV\n", dacode, voltage);
