Return Value

Error code or 0.

Usage Example

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

    /* Board initialization code omitted */

    voltage = 2.0;

    dasettings.polarity = BIPOLAR;
    dasettings.load_cal = TRUE;
    dasettings.range = 10.0;
    
    if ((result = dscVoltageToDACode(dscb, dasettings, voltage, &dacode)) != DE_NONE)
    {
        dscGetLastError(&errparams);
        fprintf(stderr, "dscVoltageToDACode failed: %s (%s)\n", 
                dscGetErrorString(result), errparams.errstring);
        return result;
    }

    printf("Voltage: %5.3lfV, DA code: %d\n", voltage, adsample);
