WebDec 27, 2024 · Cyclic redundancy check (CRC) is a common data transmission error detection technique commonly used in the data communication field. The transmit end calculates a check code for the data in a data frame based on a certain algorithm, appends the check code to the data frame, and sends the data frame to the receive end.

WebFeb 29, 2012 · The data frame is composed of an Arbitration field, Control field, Data field, CRC field, ACK field.
