Macro reference

ChangeI2CAddress

	ChangeI2CAddress
Allows the I2C Device address to be changed which in turn allows more then one RFID reader to sit on the same physical I2C bus. Returns 1 if succesful.
- BYTE	NewAddress
Range: 7 to 120 or 0x07 - 0x78
- BOOL	Return

CheckForTag

	CheckForTag
Checks to see if a tag has been detected by the module. Returns 1 if tag has been detected. Tag ID and Time since read can be accessed using GetTag and GetTime macros.
- BOOL	Return

GetTag

	GetTag
Gets the tag ID returned as a byte array. Must be called after CheckForTag has returned true. Byte array variable should be at least 6 bytes long.
- BYTE	Data
- VOID	Return

GetTagString

	GetTagString
Gets the tag ID returned as a string. Must be called after CheckForTag has returned true. String variable should be at least 13 characters long.
- STRING	Return

GetTimeMS

	GetTimeMS
Gets the time in milliseconds since the tag was read by the module. Must be called after CheckForTag has returned true.
- ULONG	Return

GetTimeS

	GetTimeS
Gets the time in seconds since the tag was read by the module. Must be called after CheckForTag has returned true.
- UINT	Return

Initialise

	Initialise
Initialises the I2C bus ready for communications with the module. Wipes the tag ID storage ready for data to be stored.
- VOID	Return

IsKnownID

	IsKnownID
Checks to see if the last tag read by CheckForTag is saved into memory. Returns true if tag is stored in memory.
- BOOL	Return

RemoveCurrentTag

	RemoveCurrentTag
Removes the current Tag ID from the known tag storage.
- VOID	Return

RemoveTagID

	RemoveTagID
Removes a specific 6-byte tag ID from the known tag storage
- BYTE	ID
Array of 6 bytes containing tag ID
- VOID	Return

StoreCurrentTag

	StoreCurrentTag
Stores the current detected tag as a known tag storage Returns true if the tag has been stored or false if there is no remaining room
- BOOL	Return

StoreTagID

	StoreTagID
Stores a specific 6-byte tag ID into the known storage Returns true if the tag has been stored or false if there is no remaining room
- BYTE	ID
Array of 6 bytes containing tag ID
- BOOL	Return

Property reference

	Properties
	Device Address
External device address used to communicate with the module. Default 125 or 0x7D
	Stored Tag Count
Number of tags IDs to store as valid IDs for use with IsKnownID. For example max number of users for a door entry system. Each stored ID requires 6 bytes of RAM memory. Max 42.
	Connections
	Channel
Channel selection
	Baud Select
Baud rate option selector
	Baud Rate
Baud rate to be used
	SDA
Pin used for SDA (data signal)
	SCL
Pin used for SCL (clock signal)
	Stop Delay
On older microcontroller devices there is a potential for the I2C hardware channel to lock up if there is not a 10ms delay between an I2C stop event and the next I2C start event. Most modern microcontrollers will not have a problem so this property can be disabled to speed up the I2C communications.
	Simulation
	Scope Traces
Selects if the component pin connections are automatically generated on the data recorder window or not. Yes: Automatically add the component pins to a group on the data recorder which will reflect the sim data during simultion. No: Do not show the pin signals on the data recorder window.
	Console Data
Selects if the console data is automatically generated or not
	API
Specifies the injector component on the panel to interact with to provide comms simulation.
