Declaration

ISerialMessagePort CreateSerialMessagePort(SerialPortName portName, byte[] suffixDelimiter, bool preserveDelimiter, int baudRate = 9600, int dataBits = 8, Parity parity = Parity.None, StopBits stopBits = StopBits.One, int readBufferSize = 512)

Returns

Meadow.Hardware.ISerialMessagePort

Parameters

Type	Name	Description
Meadow.Hardware.SerialPortName	portName	The 'SerialPortName` of port to use.
System.Byte[]	suffixDelimiter	A byte[] of the delimiter(s) that
denote the end of the message.
System.Boolean	preserveDelimiter	Whether or not to preserve the
delimiter tokens when passing the message to subscribers.
System.Int32	baudRate	Speed, in bits per second, of the serial port.
System.Int32	dataBits	Number of data bits expected in the serial
message frame. Default is 8.
Meadow.Hardware.Parity	parity	Parity enum describing what type of

cyclic-redundancy-check (CRC) bit, if any, should be expected in the
serial message frame. Default is `Parity.None`. |

| Meadow.Hardware.StopBits | stopBits | StopBits describing how many bits should be expected at the end of every character in the serial message frame. Default is StopBits.One. | | System.Int32 | readBufferSize | Size, in bytes, of the read buffer. Default is 512. |

CreateSerialMessagePort(SerialPortName, byte[], bool, int, int, int, Parity, StopBits, int)

Initializes a new instance of the ISerialMessagePort class that listens for serial messages defined by a byte[] prefix, and a fixed length.

Declaration

ISerialMessagePort CreateSerialMessagePort(SerialPortName portName, byte[] prefixDelimiter, bool preserveDelimiter, int messageLength, int baudRate = 9600, int dataBits = 8, Parity parity = Parity.None, StopBits stopBits = StopBits.One, int readBufferSize = 512)

Returns

Meadow.Hardware.ISerialMessagePort

Parameters

Type	Name	Description
Meadow.Hardware.SerialPortName	portName	The 'SerialPortName` of port to use.
System.Byte[]	prefixDelimiter	A byte[] of the delimiter(s) that
denote the beginning of the message.
System.Boolean	preserveDelimiter	Whether or not to preserve the
delimiter tokens when passing the message to subscribers.
System.Int32	messageLength	Length of the message, not including the
delimiter, to be parsed out of the incoming data.
System.Int32	baudRate	Speed, in bits per second, of the serial port.
System.Int32	dataBits	Number of data bits expected in the serial
message frame. Default is 8.
Meadow.Hardware.Parity	parity	Parity enum describing what type of

cyclic-redundancy-check (CRC) bit, if any, should be expected in the
serial message frame. Default is `Parity.None`. |

| Meadow.Hardware.StopBits | stopBits | StopBits describing how many bits should be expected at the end of every character in the serial message frame. Default is StopBits.One. | | System.Int32 | readBufferSize | Size, in bytes, of the read buffer. Default is 512. |
