Initialise

	Initialise
Initialise the component
- VOID	Return

PowerDown

	PowerDown
Power Down the device
- VOID	Return

SendMessageRxData

	SendMessageRxData
Sends message with specified identifier and awaits a reply from a slave. Returns the number of data bytes received, 254 for a timeout or 255 for a checksum error.
- BYTE	Identifier
6-Bit ID field, Range: 0x00 to 0x3F
- BYTE	ChecksumType
0=Classic (LIN 1.3), 1=Enhanced (LIN 2.0)
- BYTE	ResponseCount
Number of bytes to receive from the slave, Range: 0 to 8
- BYTE	ResponseData
Data array to pass the received data
- BYTE	Return

SendMessageTxData

	SendMessageTxData
Sends a message to the slave along with data
- BYTE	Identifier
6-Bit ID field, Range: 0x00 to 0x3F
- BYTE	ChecksumType
0=Classic (LIN 1.3), 1=Enhanced (LIN 2.0)
- BYTE	DataCount
Number of data bytes to transmit to the slave, Range: 0 to 8
- BYTE	Data
Data array to send to the slave
- VOID	Return

UpdateBaud

	UpdateBaud
Changes the UART Baud rate. 0=1200, 1=2400, 2=4800, 3=9600, 4=19200, 5=38400, 6=57600, 7=115200, 8=250000
- BYTE	new_baud
0=1200, 1=2400, 2=4800, 3=9600, 4=19200, 5=38400, 6=57600, 7=115200, 8=250000
- VOID	Return

WakeUp

	WakeUp
Wake Up the device
- VOID	Return

Property reference

	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

	Receive Timeout
The number of milliseconds to wait for incoming data to be received from the slave.
	Connections
	TX
Pin to be used for Transmit data
	TX Remap Pin
Allows the hardware transmit pin to be configured from a list of available pins based on your target device,
	RX
Pin to be used for Receive data
	RX Remap Pin
Allows the hardware receive pin to be configured from a list of available pins based on your target device,
	CS
LIN bus chip select pin
	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.
