Source Code for RFID

Hi all, I have been trying to interface the MiFare RFID reader with Arduino but am quite unsuccessful. I have the code in C, but am not sure how to implement it. Here is the code:

#define __SRC

#include "main.h"

#undef __SRC

#include "Mifare500.h"

#define MF1_S50 0

#define MF1_S70 1

#define MF0_ULIGHT 2

#define MF1_LIGHT 3

sbit Mifare500_RST=P1^4;

uchar baud_num;

uchar card_snr[8];

void serial_init(void);

uchar code Nkey_a[6] = {0xA0, 0xA1, 0xA2, 0xA3, 0xA4, 0xA5};

uchar code Nkey_b[6] = {0xff, 0xff, 0xff, 0xff, 0xff, 0xff};

main()

{

uchar cardtype=MF1_S50;

uchar i,j=40;

uchar databuf[16];

long value=1;

for(i=255;i>0;i--)

for(j=10;j>0;j--);

Mifare500_RST=0;

for(i=255;i>0;i--)

for(j=20;j>0;j--);

baud_num=2;

serial_init();

EA=1;

//i=mifs_config();

i=mifs_get_info(databuf);

// i=mifs_close();

// i=mifs_config();

// i=mifs_load_key(KEYA,15,Nkey_a);

i=mifs_load_key(KEYA,5,Nkey_b);

// i=mifs_read_E2(0x10,16,databuf);

// i=mifs_read_E2(0x20,16,databuf);

// databuf[0]=0x58;

// i=mifs_write_E2(0x11,1,databuf);

i=mifs_write_reg(0x11,0x59);

i=mifs_write_reg(0x12,0x01); //'?¡[ch937][ch8719]?[ch8747]Ø [ch733]ø?[ch937]´[ch8706]¡ø®æ?¿Î[ch9674]Ó[ch8706]ã¨[ch960]¶[ch8747]?[ch9674]ÓµÕ
