No additional examples

	PowerDown
Puts the bus into the Powered Down state driving the CS pin low.
- VOID	Return

	ListenForMessages
Listens for messages with Timeout and returns the state. Returns 255 for timeout, 254 for CRC error and 0 for none matching ID received. Returns 1-8 for a valid ID received.
- BYTE	Timeout
timeout in milliseconds to wait for incoming message, 255=Wait Forever
- BYTE	Return

	ReadDataCount
Return the data count size for Message
- BYTE	Message
Range: 1 - Num Messages
- BYTE	Return

	ReadData
Get the Message data automatically received from a specific message as part of the ListenForMessages macro.
- BYTE	Message
Message index to be read. Range: 1 - Num Messages
- BYTE	Data

- BYTE	Return

	SetData
Set the Message data to be automatically sent for a specific message as part of the ListenForMessages macro.
- BYTE	Message
Message index to write. Range: 1 - Num Messages
- BYTE	Data

- BYTE	Return

	WakeUp
Puts the bus into the Wake state driving the CS pin high.
- VOID	Return

	Initialise
Initialises the device ready for communications from the master. Puts the bus into the Wake state driving the CS pin high.
- VOID	Return

	Properties
	Bus Options
	Channel
UART Channel selector Software channels are bit banged using generic I/O pins but are not as reliable as hardware channels. Hardware channels use the selected peripheral on-board the target microcontroller.
	Baud Options
Baud rate option selector
	Baud Rate

	Messages
Number of messages the firmware is designed to listen for
	Checksum Type

	Connections
	TX
Pin to be used for Transmit data
	RX
Pin to be used for Receive data
	CS pin
LIN bus chip select pin
	MESSAGE1
	ID
Message identifier to listen for
	BYTES
Number of bytes to expent in the packet
	TX_RX
Data direction for packet
	Simulation
	Scope Traces
Selects if the scope traces are automatically added to the data recorder window or not. Simulation - draws an approximation of the UART data onto the scope trace. ICT - sets up the scope trace for incoming data and adds UART packet decoding at the correct BAUD.
	Console Data
Selects if the console data is automatically generated or not
	Console Format
Controls if the data is shown as a log with time and date stamps or just as raw data
	Console Columns
Number of characters that can be displayed on a single line of the console.
	Data Source
Simulation data source used to allow the component to connect to various remote devices Nothing - Simulation data is ignored COM port - Routes the communication data to and from a physical or virtual COM port API - Routes the communication data via a data injector component on the Panel.
