12.7.8 RFID_WRITE

Description:

Tag write operation’s parameter.

Define:

typedef struct RFID_WRITE_TAG {

HWND hWnd; //Parent window

RFIDPROC lpfnStartProc;

RFIDPROC lpfnStopProc;

BOOL32 verify;

INT32U verifyRetryCount;

RFID_18K6C_MEMORY_BANK bank;

INT32U accessPassword;

INT16U offset;

INT16U count;

Int16U pnData[8];

}RFID_WRITE;

Fields:

hWnd – The parent window which issue the Tag operation.

lpfnStartProc - Application-defined callback function. The RFID Reader Interface call

this function before execute Tag operation.

lpfnStopProc - Application-defined callback function. The RFID Reader Interface call

this function after finished Tag operation.

verify – A flag that indicates if the data written to the tag should be read back from the

tag to verify that it was successfully written. A non-zero value indicates that the tag's

memory should be read to verify.

verifyRetryCount – The maximum number of times the write should be retried if the

write-verify failure. This value must be between 0 and 7.

accessPassword – The access password for the tags. A value of zero indicates no

access password.

bank – The memory bank from which to read.

offset – The offset of the first 16-bit word to read from the specified memory bank.

count – The number of 16-bit words to read.(If this value zero and bank is EPC, the

read returns the contents of the EPC starting at the 16-bit word specified by offset

through the end of the EPC.This value must be in the range 1 to 8, inclusive.)

pnData[8] – Contains the data to be written to the tag's specified memory bank. The

high-order byte of pnData[n] is written to the tag's memory-bank byte at 16-bit

offset(offset + n). The low-order byte is write to the next byte.
