In recent years， as computer penetration in the social field and large-scale development of integrated circuits， microcontroller applications are progressing towards depth， because of its function， small volume， low power consumption， cheap， reliable operation and other features therefore particularly suitable for systems with control of more and more widely used in automatic control， intelligent instruments， meters， data collection and household appliances and other Serial communication system uses a serial work， transmission and display information so that data can pass in different This design is the use of MSC-51 Series Microcontroller AT89C51 as the central device in the design of serial communication Proteus and Keil structures in the simulation platform to assembly language as a programming language for System to achieve a number of serial communication， use of a master-slave， host to send data， receive data from the machine and displayed under the
In recent years， with the computer in the social sector and the development of large-scale integrated circuits， the application of SCM is continuously to thoroughly， because it has the strong function， small volume， low power consumption， low price and reliable， easy to use， so particularly suitable for related control and system， more and more widely used in automatic control， intelligent instrument and meter， data acquisition， and household electrical appliances， SCM serial communication system using a serial works， transfer and displaying information， data can be made in different This design is using MSC - 51 series microcontroller as the center of AT89C51 device to design a serial communication system in the building and the Keil P The simulation platform to assemble language as a programming System realizes the multi-motor serial communication， adopted masterslave， machine to send data from the machine according to theagreement， and receive
