做RFID卡的时候看到这么一串数据要写进RIFD卡中，不知道NewKey[16]这串数据代表什么意思。

 NewKey[16]={0x19,0x84,0x07,0x15,0x76,0x14,0xff,0x07,0x80,0x69,0x19,0x84,0x07,0x15,0x76,0x14};

 status=PcdWrite(7,&NewKey[0]);

char PcdWrite(unsigned char addr,unsigned char *pData)
{
    char status;
    unsigned int unLen;
    unsigned char i,ucComMF522Buf[MAXRLEN]; 
    
    ucComMF522Buf[0] = PICC_WRITE;
    ucComMF522Buf[1] = addr;
    CalulateCRC(ucComMF522Buf,2,&ucComMF522Buf[2]);
 
    status = PcdComMF522(PCD_TRANSCEIVE,ucComMF522Buf,4,ucComMF522Buf,&unLen);

    if ((status != MI_OK) || (unLen != 4) || ((ucComMF522Buf[0] & 0x0F) != 0x0A))
    {   status = MI_ERR;   }
        
    if (status == MI_OK)
    {
        //memcpy(ucComMF522Buf, pData, 16);
        for (i=0; i<16; i++)
        {    
        ucComMF522Buf = *(pData+i);   
        }
        CalulateCRC(ucComMF522Buf,16,&ucComMF522Buf[16]);

        status = PcdComMF522(PCD_TRANSCEIVE,ucComMF522Buf,18,ucComMF522Buf,&unLen);
        if ((status != MI_OK) || (unLen != 4) || ((ucComMF522Buf[0] & 0x0F) != 0x0A))
        {   status = MI_ERR;   }
    }
    
    return status;
}

正点原子

帮顶。。。。
