Usage Example

    ERRPARAMS errparams;
    DSCADSETTINGS adsettings;
    DSCB dscb;
    DSCSAMPLE sample;
    DFLOAT voltage;
    BYTE result;

    /* Board initialization code omitted */

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

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

   printf("Sample readout: %hd, Actual voltage: %5.3lfV\n", sample, voltage);
