Unsigned char revbuf[20]={0};
st= fw_pro_reset(icdev,&len,revbuf);
Remark: You should call function “fw_card” once first before this function is
called.
__int16 fw_pro_commandlink(int ICDev,unsigned char slen,unsigned char *
sbuff,unsigned char *rlen,unsigned char * rbuff,unsigned char tt,unsigned char
FG);
Description
APDU data exchange function
Parameters
icdev: Value of Device Handle.
slen: the length of information to send
sbuff: command to send
rlen: length of returned information
rbuff: returned information
tt: delay time, unit: 10ms
FG: split length, it is recommended that this value be less than 64
Return Value
0 if successful; otherwise, Nonzero.
Example
__int16 st;
unsigned char srvBuffer[256]={0x80,0x84,0x00,0x00,0x10};
unsigned char revBuffer[256]={0};
unsigned char sendlen=5;
unsigned char ftt=9;//to delay 90ms
unsigned char fFG=60;//to send 60 bytes each time
unsigned char revlen;
st=fw_pro_commandlink(icdev,sendlen,srvBuffer,&revlen,revBuffer,ftt,fFG);
2.10 Desfirecard specific function
int fw_anticoll2(int icdev,unsigned char _Bcnt,unsigned long *_Snr);
Description
The second anti-collision
Parameters
icdev: Value of Device Handle.
_Bcnt: Anti-conflict level, set 0 here
_Snr: Return 5 bytes of card information, the first byte is 0x88, the other four
bytes are the high byte of the card number .
Return Value
0 if successful; otherwise, Nonzero.
