主程序中寫卡部分代碼
void my_register(void)
{
while(1)
{
int i,j;
HandleConfigMenu('A');//讀卡
my_status = PcdSelect(UID);
PcdHalt(); //我是這里設置的休眠，不知道會不會對讀寫有影響
printf("Select:%x\n", my_status);
if(MI_OK != my_status) continue;
my_status = PcdAuthState(PICC_AUTHENT1A , ReadWriteArea, ResetKey, UID);//尋卡
if(MI_OK == my_status)
{
printf("The card has been registered!!!\n");
usleep(500000);
break;
}
else
{
printf("Check\n");
my_status = PcdWrite(ReadWriteArea, SetKey_write);
printf("PcdWrite: %x\n", my_status);
printf("WRITE ...\n");
if(MI_OK == my_status)
{
my_status = MI_ERR;
printf("Registering...\n");
buzzer_control(DEVICE_BUZZER,BUZZERON);

下面貼出來PcdWrite、PcdAuthState相關代碼，有懂的朋友幫我看一下是不是哪里參數設置錯了

{

unsigned int unLen;
unsigned char i,ucComMF522Buf[MAXRLEN];

CalulateCRC(ucComMF522Buf,2,&ucComMF522Buf[2]);
status = PcdComMF522(PCD_TRANSCEIVE,ucComMF522Buf,4,ucComMF522Buf,&unLen);
if ((status != MI_OK) || (unLen != 4) || ((ucComMF522Buf[0] & 0x0F) != 0x0A)) //根據終端打印信息，是這里出錯
{ printf("1.\n");
status = MI_ERR; }
if (status == MI_OK)
{
for (i=0; i<16; i++)
{ ucComMF522Buf[ i] = *(pData+i); }

}
