Cyclic Redundancy Check (CRC)

A cyclic redundancy check (CRC) is an error-detecting code commonly used in digital networks and storage devices to detect accidental changes to digital data.

Wow, I see this in the VESC driver codebase: https://github.com/f1tenth/vesc/blob/main/vesc_driver/src/vesc_packet.cpp

More powerful error-detection coding.
