基于AT89S52单片机的电子万年历系统设计

摘要

To design a convenient household electronic calendar which has simple circuit, accurate time and multi-function, microcontroller AT89S52 is used for programmable control. The external temperature sensor and LCD (liquid crystal display) are adopted to realize the accurate display of date and time, humanization setup of alarm clock and and real-time display of ambient temperature. The modularization management is employed in the system structure design. Since its program is compiled with C language, it has low cost of hardware and strong transportability which is helpful to the post-expansion. It is suitable for home users.%为设计一款电路简洁、走时准确、功能齐全的家用电子万年历,利用AT89S52单片机进行可编程控制,结合外围温度传感器、液晶屏等,实现了万年历的时间日期准确显示,人性化的闹钟设置以及环境温度的实时显示.设计结构模块化管理,基于C语言编写,可移植性强,便于后期扩展,硬件成本低,适合家庭用户使用.
