Abstract
In the control system of microcomputer and 8051 single chip,lack of a formal communication interface between a microcomputer and single chip,so can't communicate.If one microcomputer communicate to a single chip,the developer must make the designs.In order to communication between microcomputer and single chip,establishes communication protocols, achieving TXD and RXD use of single chip's serial port,microcomputer sends data to 8250 adapter through I/O instruction,the communication between microcomputer and 8051 single chip is implemented.
