参数 |
类型 |
方向 |
含义 |
ReaderID |
int |
IN |
所要获取的设备标示ID,范围0x0000-0xFFFF,如果未知,则ReaderID=0 |
Model |
unsigned char |
IN |
Model标识(Flag): 0x01->对已选择的标签进行操作,PUID可为任意值, Option_flag = 0; 0x02->对PUID指定的标签进行操作,PUID为当前操作标签的UID, Option_flag = 0; 0x04->对已选择的标签进行操作,PUID可为 任意值, Option_flag = 1; 0x06->对PUID指定的标签进行操作,PUID为当前操作标签的UID, Option_flag = 1; |
PUID |
unsigned char * |
IN |
卡的序列号UID(8Byte) |
StartBlockID |
unsigned char |
IN |
开始块号 |
BlockNums |
unsigned char |
IN |
块数量 |
PData |
unsigned char * |
OUT |
读到的数据 |
PLen |
unsigned char * |
OUT |
读到的数据PData的长度 |
返 回 值:大于0为成功,小于0为失败
注意:
1.
Model的解释见 YW_ISO15693_Reset_To_Ready
中注释。
2. 若Option_Flag = 1,返回的数据带安全状态字节(Block Security
Status),格式为: 块安全状态字节 + 块数据;反之不带安全状态字节。
