Design of IC-Card Read-Write Device Based on
89C2051 Single-Chip Microcomputer
Abstract
Design of IC-card read-write device based on 89c2051 single-chip microcomputer is according to electric circuit foundation, imitating electronics technique, arithmetic figure electronics technique, the core is technique of connect port of machine of single-chip microcomputer and Inter-Integrated Circuit bus communication, and this paper is about IC-card read-write device research and manufacturing, asking for help of VB procedure design. This system’s exploit is making use of single-chip microcomputer’s characteristics: quick, conveniently, stabilizing, efficiently and cheap, also it’s a set of computer management system, suitable for EDA network laboratory of electronics department of our school .
The contents of this design are: the basic frame of system’s hardware makes use of 89C2051 model single-chip microcomputer’s expanding function of outstanding outer circle electric circuit; according to the Inter- Integrated Circuit bus communication principle, we use single-chip microcomputer imitate Inter-Integrated Circuit bus main device in order to do reading and writing operation to IC-card parked AT24C16 core slice ; based on sting-export work principle, single-chip microcomputer can realize asynchronous data communication though sting-export and PC(personal computer) ,moreover, PC(personal computer) can control IC-card read-write device; in PC(personal computer) aspect, the sting export test procedure and the simple visible write and read operation procedure are both use Visual Basic 6.0 computer language, in the future ,we can expand database on base of this procedure.
Through the hardware’s design, we hope to realize basic foundation of IC-card read-write device.
