基于AT89C51电子万年历的设计及论文

本文提出了一种基于AT89C51单片机的万年历设计方案，该方案以AT89C51单片机作为主控核心，与时钟芯片DS1302、DS18B20温度传感器、按键、LCD显示等模块组成硬件系统。在硬件系统中设有5个独立按键和一个LCD显示器，能显示丰富的信息，根据使用者的需要可以随时对时间进行校准、选择时间等，综上所述此万年历具有读取方便、显示直观、功能多样、电路简洁、成本低廉等诸多优点，符合电子仪器仪表的发展趋势具有广阔的市场前景。

Abstract

In this paper, a calendar is designed based on AT89C51 MCU.The proposal uses a single-chip microcomputer AT89C51 as the Master Control chip. The hardware system makes up of the clock chip DS1302, temperature sensor DS18B20, buttons, LCD display modules. Hardware system has five independent buttons and a LCD display, which can display a wealth of information. In accordance with the needs of users, time can be calibrated at any time, chosen the time and so on. To sum up this calendar has some advantages, for example easy to read, showing intuitive, feature-rich, circuit simplicity, low cost. In line with the electronic instrumentation of the development trend, the calendar has the broad market prospects.
