USB讀卡器windows JNI開發(fā)例程
windows在java中使用JNI調(diào)用usb讀卡器的動態(tài)庫yw60x.dll
public static void main(String[] args)
{
int ReaderID=1;
int Requestmode=38;
short Cardtype[]=new short[1];
byte LenSn[] = new byte[1];
byte CardNo[] = new byte[8];
byte Key[]=new byte[]{(byte)0xFF,(byte)0xFF,(byte)0xFF,(byte)0xFF,(byte)0xFF,(byte)0xFF};
byte BlockData[]=new byte[16];
YOWORFID rfidreader = new YOWORFID();
rfidreader.YW_USBHIDInitial();
int rt =0;
{
rt =rfidreader.YW_RequestCard(ReaderID,Requestmode,Cardtype);
//if(rt<=0)continue;
rt = rfidreader.YW_AntiCollide(ReaderID,LenSn,CardNo);
HexToStr(CardNo,LenSn[0]);
rt =rfidreader.YW_CardSelect(ReaderID,LenSn[0],CardNo);
rt =rfidreader.YW_KeyAuthorization(ReaderID,96,4,Key);
System.out.printf("KeyAuthorization=%d",rt);System.out.println();
rt =rfidreader.YW_ReadaBlock(ReaderID,4,16,BlockData);
System.out.printf("YW_ReadaBlock=%d",rt);System.out.println();
if(rt>0){HexToStr(BlockData,16);}
}
rfidreader.YW_Led(ReaderID,1,1,1,3,0);
rfidreader.YW_USBHIDFree();
}
}
