B.3
Read single block
The Read Single Block ISO 15693 command is performed by calling the
ReadRF_single_DataLogger() function.
.
Table 12.
ReadRF_single_DataLogger()
Function description
Prototype ^{Function ReadRF_single_DataLogger (lngAddLow As Long,}
lngDataSize As Long, lngNbByteAddress As Long) As String
lngAddLow: address the read operation starts from
Parameters lngDataSize: number of data bytes to be read
lngNbByteAddress: number of bytes used to code the address
Returned
value
String
ReadRF_single_DataLogger(0, 4, 2) returns the 4 bytes read from address
Example _{0 coded on 2 bytes.}
B.4
Read Multiple Block
The Read Multiple Block ISO 15693 command is performed by calling the
ReadRF_multiple_DataLogger() function:
.
Table 13.
ReadRF_multiple_DataLogger()
Function description
