CRC8 Class Reference

List of all members.


Detailed Description

CRC8 is a class to contain an implementation of the Cyclic-Redundency-Check CRC8 for the iButton.

The CRC8 is used in the 1-Wire Network address of all iButtons and 1-Wire devices.

CRC8 is based on the polynomial = X^8 + X^5 + X^4 + 1.
