摘要
介绍了IIC总线芯片基本性能及时序、总线结构,设计了银行排队系统,介绍带IIC总线的芯片PCF8563,通过软件的方法,实现IIC总线在MCS-51系统中的使用,有效利用了现有资源,实现排队功能,提高银行工作效率,减少顾客等待时间。系统通过keilc进行仿真实现银行排队预期功能。
This article describes IIC bus chip＇s basic functions, timing and bus architecture, designs bank queuing system and introduces that the chip PCF8563 with the IIC bus with the help of software realizes the application of IIC bus in MCS-51 systems which is able to make full use of existing resources, improve bank working efficiency and reduce customers＇ waiting time. The system was simluted with Keil c which could reach the position.
