WebA bare-bones C# implementation of the CRC8 checksum algorithm used in our OEM spectrometers. Web2 days ago · For example, if your data packet contains bytes [0x01, 0x02, 0x03], then the sum would be (0x01 + 0x02 + 0x03) = 0x06. Taking the complement of this value gives you the 8-bit checksum value, which is (0xFF - 0x06) = 0xF9. To calculate the 16-bit checksum, you need to split your data packet into two-byte words and add them together.

Web1) why bit operator is used? 1）为什么使用位运算符？ & 0xFFFF sets the two high bytes of the checksum to 0, so sum1 is simply the lower 16 bits of the checksum. & 0xFFFF将校验和的两个高字节设置为0，因此sum1仅是校验和的低16位。. 2) why bit operator is used? 2）为什么要使用位运算符？, why is it shifted? ，为什么要转移？ WebAug 30, 2012 · Maybe this is enough for you.
