实时时钟电路的单片机仿真设计

Simulation Design of the Real-time Clock Circuit Based on Single Chip

介绍一种应用Proteus单片机仿真软件结合Kile代码编译软件实现的实时时钟电路仿真设计,该设计以AT89C51单片机为控制核心,通过高性能、低功耗、带RAM的实时时钟芯片DS1302,产生秒、分、时、日、月及年六个时标信号,并由外部触发按键,对时间进行加减调节,最终将当前日期时间信息显示在1602液晶显示屏上。

One kind of real-time clock displaying circuit model is introduced, which uses Proteus combining with Kile as the design software.The 8051 singlechip is used as the control unit.The DS1302 with high performance ,low-power, and RAM is used to produce six time signals of second, minute, hour, day, month and year. The current date-time information displays in 1602 LCD screen by triggering external button to plus/minus time.
