之前自己用這個模塊的時候也找了很多了歷程來測試，但是都是沒有通過，最后得出的結論是spi通信的問題，，自己也懶得去找問題，，所以就擱置了現在把調試通過的程序拿來分享給大家，可以讀卡的，其他功能需要自己開發哦
單片機源程序如下:
- #include "lpcreg.h"
- #include "main.h"
- #include "mfrc522.h"
- #include <STDIO.H>

- //M1卡的某一塊寫為如下格式，則該塊為錢包，可接收扣款和充值命令
- //4字節金額（低字節在前）＋4字節金額取反＋4字節金額＋1字節塊地址＋1字節塊地址取反＋1字節塊地址＋1字節塊地址取反
- unsigned char code data2[4] = {0,0,0,0x01};
