| Abstract: | This paper describes a method of the data Serial communication between PC microcomputer and mutliple single-chip microcomputers of IC card dining hall management system. To insure the communication reliability between primary computer and secondary computers, RS-485 inter-face is used, and a communication card centring on 8031 of multiple computers is designed. This paper gives some diagrams of softwares and interface hardwares. |
