А если так?

    BarcodeEAN128   BarcodeEAN128;
    str             barcode = "100653005555555555";
    ;
    BarcodeEAN128 = new BarcodeEAN128();
    barcode = Barcode::insertModulo10CheckDigit(barcode, strlen(barcode));
    BarcodeEAN128.decode("00" + barcode);
    BarcodeEAN128.encode();
    info(BarcodeEAN128.barcodeStr());
    info(BarcodeEAN128.barcodeStrHR());
