All coeffi-cients, like x2 or x15, are represented by a logical 1 in 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.
