"Webb17 juli 2011 · For example, the simplest checksum is to sum up all the bytes of a transmission, computing the sum in an 8-bit counter. This value is appended as the last byte of the transmission. The idea is that upon receipt of n bytes, you sum up the first n- 1 bytes, and see if the answer is the same as the last byte. Since this is a bit awkward, a … " - Simple checksum
