                       display_cardnum();//显示寻到的卡的序列号

它在一个while循环里 while ( 1 )
    while ( 1 )
     {  
       LED_1  =0;
         delay(2000);
        LED_1  =1;
        delay(2000);

        delay(2000);
    //    abc();
    status = PcdRequest(PICC_REQALL, g_ucTempbuf);//寻卡
         if (status != MI_OK)
        {     continue;       }
         else

是执行下一次while循环吗

恩呢，好的，谢谢

也就是说如果if表达式成立，continue后面的语句总是不执行？
