    }
}

三、卡密钥认证

void MainWindow::on_pb_authkey_clicked()
{    
    if(!checkdllos()){return;}       //判断运行目录内动态库文件是否存在
    if (myiso15693authkey != NULL){

            ui->lineEdit_uid->setFocus();
            return;
        }

        unsigned char authkeybuf[4];
        QString authkeystr=ui->lineEdit_authkey->text().trimmed();

            return;
        }

        unsigned char passwordid;
        switch(ui->comboBox_keymodel->currentIndex()){
        case 4:
            passwordid=0x10;
            break;
        case 3:

            break;
        case 2:

            break;
        case 1:

            break;
        default:

    }
}

四、更改卡片密钥

void MainWindow::on_pb_editkey_clicked()
{
    if(!checkdllos()){return;}       //判断运行目录内动态库文件是否存在
    if (myiso15693writekey != NULL){

        QString uidstr=ui->lineEdit_uid->text().trimmed();
        int checkbuflen=checkhexdata(uidstr,uidbuf);
        if (checkbuflen!=8){
            QMessageBox::critical(NULL, "提示", "需要操作的卡片UID错误，可先执行寻卡操作获取UID！");
            ui->lineEdit_uid->setFocus();
            return;

            QMessageBox::critical(NULL, "提示", "卡片新密钥输入错误，请输入8位16进制新密钥!");
            ui->lineEdit_newkey->setFocus();
            return;
        }

        unsigned char passwordid;
        switch(ui->comboBox_keymodel->currentIndex()){
        case 4:

        if(status==0){
            mypcdbeep(30);
            QMessageBox::information(NULL, "提示", "UID："+ uidstr+" 更改卡密钥成功！");

            }else{
                 disperrinf(status);
            }
        }

    }else{

    }
}

五、读取卡内数据

void MainWindow::on_pb_read_clicked()
{
    if(!checkdllos()){return;}      //判断运行目录内动态库文件是否存在
    if(myiso15693readblock != NULL){
        unsigned char status;
        unsigned char flags;
        unsigned char startblock;
        unsigned char blocknum;
        unsigned char uid[8];
        unsigned char revlen[1];
        unsigned char revbuf[255];

        ui->plainTextEdit_data->setPlainText("");

        ui->lineEdit_flags->setText("22");
        flags=34;

        startblock=ui->spinBox_star->value();
        blocknum=startblock+ui->spinBox_num->value();

        QString uidstr=ui->lineEdit_uid->text().trimmed();
        if(uidstr.length()==16 and checkinput(uidstr)){
            bool ok;
            for(int i=0;i<8;i++){
                uid[i]=QString(uidstr.mid(i*2,2)).toInt(&ok,16);
            }
        }else{
            QMessageBox::critical(NULL, "提示","请先寻找卡片或输入16位16进制UID！");
            ui->lineEdit_uid->setFocus();
            return;
        }

        QString blockdata="";
        while (startblock<blocknum){
            status = myiso15693readblock(flags, startblock, 1, uid, revlen, revbuf);
            if(status==0){
                int j=0;

                while(j<revlen[0]){
                    blockdata=blockdata+QString::asprintf("%02X ", revbuf[j]);
                    j++;

            }
        }
        if(startblock==blocknum){
            mypcdbeep(30);
            ui->plainTextEdit_data->setPlainText(blockdata);
            QMessageBox::information(NULL, "提示", "读卡成功，卡片UID："+uidstr);
        }else{
             QMessageBox::critical(NULL, "提示",QString::asprintf("在读取第 ：%d", startblock)+"，块时返回错误代码："+QString::asprintf("%d", status));
        }
    }else{

    }
}

六、写入数据

void MainWindow::on_pb_write_clicked()
{
    if(!checkdllos()){return;}      //判断运行目录内动态库文件是否存在
    if(myiso15693writeblock != NULL){
        unsigned char status;
        unsigned char flags;
        unsigned char eachblocksize;
        unsigned char startblock;
        unsigned char blocknum;
        unsigned char uid[8];

        unsigned char writebuf[2000];

        ui->lineEdit_flags->setText("22");
        flags=34;

        startblock=ui->spinBox_star->value();
        blocknum=startblock+ui->spinBox_num->value();
        switch(ui->comboBox_cardtype->currentIndex()){
        case 0:
             eachblocksize=4;
             break;
        case 1:
             eachblocksize=8;
             break;
        default:
             eachblocksize=32;
             break;
        }
        int writelen=blocknum*eachblocksize;

        QString uidstr=ui->lineEdit_uid->text().trimmed();
        if(uidstr.length()==16 and checkinput(uidstr)){
             bool ok;
             for(int i=0;i<8;i++){
                uid[i]=QString(uidstr.mid(i*2,2)).toInt(&ok,16);
             }
        }else{
             QMessageBox::critical(NULL, "提示","请先寻找卡片或输入16位16进制UID！");
             ui->lineEdit_uid->setFocus();
             return;
        }

        for(int i=0;i<2000;i++){writebuf[i]=0x00;}


        //检测写卡数据
        QChar ch;
        QString writinf = ui->plainTextEdit_data->toPlainText().trimmed();
        QString writinf1 = "";
        int m = 0;
        int n = 0;
        char s;

        if(writinf.length()<1){
             QMessageBox::critical(NULL, "提示", "请输入正确的16进制写卡数据！");
             ui->plainTextEdit_data->setFocus();
             return;
        }

        ch = writinf.at(0);
        s = writinf.at(0).toLatin1();
        for(int i=0; i<writinf.length() ; i++)
        {
             ch = writinf.at(i);
             s = writinf.at(i).toLatin1();
             if((('0' <= s) && (s <= '9')) || (('A' <= s) && (s <= 'F')) || (('a' <= s) && (s <= 'f')))
             {
                writinf1 += ch;
                n++;
                if(n==2){
                    bool ok;
                    writebuf[m++] = writinf1.toInt(&ok,16);
                    writinf1 = "";
                    n = 0;
                }
             }
             else if(s == ' '){

             }
             else
             {
                QMessageBox::critical(NULL, "提示", "写卡数据错误，请输入正确的16进制数据！");
                ui->plainTextEdit_data->setFocus();
                return;
             }
        }

        int i=0;
        while (startblock<blocknum){
             unsigned char wbuf[eachblocksize];
             for(int j=0;j<eachblocksize;j++){
                wbuf[j]=writebuf[i+j];

             }
             status = myiso15693writeblock(flags, startblock, 1, uid, eachblocksize, wbuf);
             if(status==0){
                startblock=startblock+1;
                i=i+eachblocksize;
             }else{

                break;
             }
        }
        if(startblock==blocknum){
            mypcdbeep(30);
            QMessageBox::information(NULL, "提示", "写卡成功，卡片UID："+uidstr);
        }else{
             QMessageBox::critical(NULL, "提示",QString::asprintf("在写第 ：%d", startblock)+"，块时返回错误代码："+QString::asprintf("%d", status));

    }
}

七、开启块密钥保护功能

void MainWindow::on_pb_setblockauth_clicked()
{
    if(!checkdllos()){return;}       //判断运行目录内动态库文件是否存在
    if (myiso15693protectblock != NULL){
        unsigned char uidbuf[8];
        QString uidstr=ui->lineEdit_uid->text().trimmed();
        int checkbuflen=checkhexdata(uidstr,uidbuf);
        if (checkbuflen!=8){
            QMessageBox::critical(NULL, "提示", "需要操作的卡片UID错误，可先执行寻卡操作获取UID！");
            ui->lineEdit_uid->setFocus();
            return;
        }

        unsigned char ctrlword=0x04;
        unsigned char blockpoint=ui->spinBox_hllockb->value();      //高低块分隔地址
        unsigned char extprotectstatus=ui->comboBox_lowblock->currentIndex()+ui->comboBox_highblock->currentIndex()*16;  //密钥保护方式
        unsigned char status=myiso15693protectblock(ctrlword,uidbuf,blockpoint,extprotectstatus);
        if(status==0){
            mypcdbeep(30);
            QMessageBox::information(NULL, "提示", "UID："+ uidstr+" 的卡块密码保护设定成功！");
        }else{
            if(status==47){
                QMessageBox::critical(NULL, "提示", QString::asprintf("错误代码：%d", status)+"，必须都认证读取密码和写入密码成功后再进行块密码保护设定！");
            }else{
                disperrinf(status);
            }
        }
    }else{
        QMessageBox::critical(NULL, "提示", "函数'iso15693protectblock'未正确载入，请查询 "+runDir+" OUR_MIFARE.dll、libOURMIFARE.so文件版本是否正确！");
    }
}
