JavaScriptView Source Request Example

function CalculateChecksum(buffer, offset, length);

Parameters

buffer Byte: Buffer image over which to calculate checksum.
offset Int32: Start index into buffer to calculate checksum.
length Int32: Length of data within buffer to calculate checksum.

Return Value

UInt16
Checksum over specified portion of buffer.

Remarks

Override with needed checksum calculation for particular protocol.

Example

This example provides a CRC-CCITT checksum:


            using GSF.IO.Checksums;
            
            protected override ushort CalculateChecksum(byte[] buffer, int offset, int length)
            {
                // Return calculated CRC-CCITT over given buffer...
                return buffer.CrcCCITTChecksum(offset, length);
            }
