C# Class GSF.IO.Checksums.Crc16

Generates a byte-wise 16-bit CRC calculation.

2-byte (16-bit) CRC: The generating polynomial is

16 15 2 1

G(X) = X + X + X + X

Public Methods

Method	Description
Crc16 ( ) : System	Creates a new instance of the Crc16 class. The checksum starts off with a value of 0x0000.
Crc16 ( ChecksumType checksumType ) : System	Creates a new instance of the Crc16 class.
Reset ( ) : void	Resets the CRC-16 data checksum as if no update was ever called.
Reset ( ChecksumType checksumType ) : void	Resets the CRC-16 data checksum as if no update was ever called.
Update ( byte value ) : void	Updates the checksum with the byte value.
Update ( byte buffer, int offset, int count ) : void	Adds the byte array to the data checksum.

Creates a new instance of the Crc16 class. The checksum starts off with a value of 0x0000.

public Crc16 ( ) : System
return	System

Creates a new instance of the Crc16 class.

public Crc16 ( ChecksumType checksumType ) : System
checksumType	ChecksumType	/// Type of calculation to perform, CRC-16 or ModBus. ///
return	System

Resets the CRC-16 data checksum as if no update was ever called.

public Reset ( ) : void
return	void

Resets the CRC-16 data checksum as if no update was ever called.

public Reset ( ChecksumType checksumType ) : void
checksumType	ChecksumType	Type of CRC calculation. CRC-16 resets to 0x0000, ModBus resets to 0xFFFF
return	void

Updates the checksum with the byte value.

public Update ( byte value ) : void
value	byte	The value to use for the update.
return	void

Adds the byte array to the data checksum.

public Update ( byte buffer, int offset, int count ) : void
buffer	byte	The buffer which contains the data
offset	int	The offset in the buffer where the data starts
count	int	The number of data bytes to update the CRC with.
return	void
