1 Introduction This Chapter gives basic information about CAENRFID Software Development Kit (SDK).
Overview on SDK CAEN RFID provides a Software Development Kit (SDK) aimed to facilitate the software developers in interfacing with its readers. The SDK provides Application Program Interfaces (API) for three programming languages: C, Java and J#/C#/Visual Basic .NET. The functionalities and the behaviors exported by the libraries are exactly the same for all the languages but, due to the syntax differences between them, there are differences in the implementation of functions and methods. Java and .
needed in order to maintain the communication active. The function returns a "handle" (very similar to the handles used in managing files) that have to be used in any subsequent function calls relative to that reader. At the end of the operation, a call to the CAENRFID_End function permits to close the communication link and to free the internal data structures. Return data mechanism As seen in the Error Handling paragraph, all the C functions return a numeric error codes.

Syntax: C# representation: public byte[] GetPC() Java and Android representation: public byte[] GetPC() GetReadPoint Method Description: This method returns the read point that has detected the tag.
GetSource Method Description: This method returns the name of the logical source that has detected the tag. Return value: The name of the logical source that has detected the tag. Syntax: C# representation: public CAENRFIDLogicalSource GetSource() Java and Android representation: public CAENRFIDLogicalSource GetSource() GetTID Method Description: This method returns the tag's TID (valid only for EPC Class 1 Gen 2 tags). Return value: An array of bytes representing the tag's TID.
GetType Method Description: This method returns the air protocol of the tag. Return value: The air protocol of the tag. Syntax: C# representation: public new CAENRFIDProtocol GetType() Java and Android representation: public CAENRFIDProtocol GetType() GetXPC Method Description: This method returns the tag’s XPC words. Return value: The tag’s XPC words.
4 Event Handling This chapter gives a description of CAENRFID event handling.
Event Handling Standard tag's detection method (InventoryTag) is based on a polling mechanism: a call to the InventoryTag method/function results in a single read cycle and the detected tags in that cycle are returned.
EventInventoryTag Method Description: A call to this method will start a sequence of read cycle on each read point linked to the logical source. The readings will be notified to the controller via event generation. Parameters: Name Mask MaskLength Position Flag pCallBack Description A byte array representing the bitmask to apply. A value representing the bit-oriented length of the bitmask. A value representing the first bit where the match will start. A bitmask representing the InventoryTag options.
Remarks: Depending on the air protocol setting it will execute the appropriate anticollision algorithm. This version of the method permits to specify a bitmask for filtering tag's populations as described by the EPC Class1 Gen2 (ISO18000-6C) air protocol. The filtering will be performend on the memory bank specified by bank parameter, starting at the bit indicated by the Position index and for a MaskLength length. The method will return only the tags that match the given Mask.
C# Event Handling CAENRFIDEventArgs Class The CAENRFIDEventArgs class defines the CAENRFID event arguments. getData Method Description: This method returns the event object value. Return value: The value of the event object. Syntax: C# representation: public CAENRFIDNotify[] getData() CAENRFIDEventHandler Delegate CAENRFIDEventHandler delegate declaration. Parameters: Name Event Description the Data Event.
Java and Android Event Handling CAENRFIDEvent Class The CAENRFIDEvent class defines the CAENRFID event arguments. getData Method Description: This method returns the event object value. Return value: The value of the event object. Syntax: Java and Android representation: public java.util.ArrayList getData() CAENRFIDEventListener Interface The listener interface for receiving CAEN RFID events. CAENRFIDTagNotify Description: This method is invoked when an action occurs.
C Event Handling CAENRFID_INVENTORY_CALLBACK This function prototype defines the type of the user defined event handler (see the CAEN RFID API User Manual.
5 Enumerations Description This chapter gives a description of CAENRFID enumerations. It contains these topics: CAEN RFID API – Reference Manual • CAENRFIDBitRate Enumeration • CAENRFIDLogicalSourceConstants Enumeration • CAENRFIDLogicalSource.
CAENRFIDBitRate Enumeration The CAENRFIDBitRate Enumeration gives a list of the supported radiofrequency profiles.
CAENRFIDLogicalSourceConstants Enumeration The CAENRFIDLogicalSourceConstants Enumeration gives a list of constants used for the configuration of the logical sources. Detailed explanation of the settings can be found in the EPC Class 1 Gen 2 and ISO 18000-6B specification documents.
CAENRFIDLogicalSource.InventoryFlag Enumeration The CAENRFIDLogicalSource.InventoryFlag Enumeration gives a list of constants used for the configuration of the inventory function that comes with Flag parameter. Syntax: C# representation: public enum CAENRFIDLogicalSource.InventoryFlag Java and Android representation: public final class CAENRFIDLogicalSource.InventoryFlag C representation: typedef enum CAENRFIDLogicalSource.InventoryFlag; In the following table, the CAENRFIDLogicalSource.
CAENRFIDPort Enumeration The CAENRFIDPort Enumeration gives a list of the communication ports supported by the CAEN RFID readers. Syntax: C# representation: public enum CAENRFIDPort Java and Android representation: public final class CAENRFIDPort C representation: typedef enum CAENRFIDPort; Remarks: In order to align the three libraries, the members name in C language have changed, now reporting the CAENRFID_ suffix, but the value of the members is the same of the previous library version.
CAENRFIDReadPointStatus Enumeration The CAENRFIDReadPointStatus gives a list of the possible ReadPoint status values.
CAENRFIDRFRegulations Enumeration The CAENRFIDRFRegulations gives a list of country radiofrequency regulations. Syntax: C# representation: public enum CAENRFIDRFRegulations Java and Android representation: public final class CAENRFIDRFRegulations C representation: typedef enum CAENRFIDRFRegulations; Remarks: In order to align the three libraries, the regulations, previously declared as #define, are now members of an enumeration, but the value of the members is the same of the previous library version.
CAENRFIDRS232Constants Enumeration The CAENRFIDRS232Constants gives a list of settings for the serial port configuration.
CAENRFIDSelUnselOptions Enumeration The CAENRFIDSelUnselOptions gives a list of operations supported by the Group Select/Unselect command (valid only for the ISO18000-6B air protocol).
CAENRFIDTag.MemBanks Enumeration The CAENRFIDTag.MemBanks enumerates the bank name of a generic ISO18000-6C tag.
6 CAENRFID Obsolete Methods This chapter gives a list of CAENRFID obsolete methods, functions, members and data types.
Below it is available a list of obsolete methods, functions, members and data types for the three different program languages. It is recommended not to use these methods since they will not be available in new reader's firmware release. Some of these obsolete methods have been replaced by new ones as specified in the table below.
