1-Wire - What is CRC

A Cyclic Redundancy Check (CRC) ensures that data read from from a 1-Wire bus is not corrupted. 1-Wire uses an 8-bit CRC. When transmitting message through 1-Wire an additional byte is sent which is computed by XORing all other bytes together. The host and client both generate this value and compare. If it does not match an error has occurred. Read more.
