This 8-bit Checksum Calculator can be used to calculate the 8-bit Checksum of a sequence of hexadecimal values or bytes. The bytes and be entered in a string of two character. The character can be entered in either upper case or lower case. 8-bit Checksum is also called the 2's compliment of addition of all bytes.
Enter Hexadecimal value separated by space e.g. if you have "0xaa 0xaa 0xaa" then enter "aa aa aa" and press
the "calculate" button to calculate the 8-bit checksum.
the checksum of string of all entered bytes and the checksum will be equal to zero.
The checksum Entered byte string "aa aa" = "ac"
The checksum of "aa aa ac" = "0"
