摘要
针对ARM CPU和税控收款机的特点,设计开发了用以实现消费交易功能的磁卡接口平台。给出了S3C2410A与磁卡的硬件接口电路连接,规划了驱动状态转换图,对核心驱动函数功能进行了细致描述。正向刷卡和反向刷卡的良好实现,充分说明了该设计方案的正确可行性。
The platform of magcard that realizes the function of trade is designed and realized in this paper, as to ARM CPU and the fiscal cash register. The connection of S3C2410A and magic card is introduced. At the same time we give and explain the every driving state. Finally we give the description of main driving functions. The stable running of trade remarks the correct and feasible design for hardware and the perfectible function for software.
