(The reasonable termination of the communication function of the single-chip microcomputer is the key factor for the effective transmission of the network communication of the single-chip microcomputer, so it is necessary to conduct a sufficient research on the network communication of the single-chip microcomputer. This article analyzes the use of communication based on PICl6F876A microcontroller based on the importance of single-chip network communication clearly, and further discusses the method and termination of network communication based on single-chip microcomputer.)
