摘要
基于三星公司的S3C44B0X处理器的嵌入式开发平台,提出了一种用通用I/O口实现与IC卡通信的设计方案,其中包括硬件接口设计和软件设计等方面的说明,特别是硬件实现上要注意的很多问题。而且使用通用的高级语言C实现了通用I/O口和IC卡间通信的时序。通过定义不同的数据格式和软件方面做相应的修改,即可实现不同的IC卡的应用。
Based on the Sumsung ARM S3C44BOX embedded development platform, a design scheme of data communication between IC card and general purpose I/O ports is presented, including the instruction of hardware interface design and software design. Problems should be noticed in hardware implementation are put forward. The scheduling of data communication between general purpose I/O ports and IC card is implemented by using the common advanced language C. By defining different data transmission formats with proper software adjustment, various IC cards can be easily implemented.
