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. This is derived from code in the OWdotNET project.
