Application of the coding to data communicating in the microprocessor

The serial communication function of microprocessor is often used in a MCS - 51 microprocessor application system. Because of the influence of the working environment, data will be disturbed and mistake will occur in the process of transmission. In this paper, based on the serial port of the microprocessor, fault-tolerant technology of data communication can be achieved. For the interference problem existed in communication part of current data communication control system, the data is coded by using hamming code error correction technology, and the error is corrected at the receiving end. In this paper, the complicated hamming code algorithm is simplified, which can facilitate the realization of the programming. In addition, this paper analyzes the principle of coding and decoding of hamming code, introduces the process of coding and decoding in detail, and analyzes the anti-interference ability of serial communication by using the hamming code coding technique.
