** 职业技术学院毕业论文课题: 基于 AT89C51 电子万年历的设计与仿真专业学生姓名班级学号指导教师完成日期摘要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 AT89C5 1 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 AT89 C51 MCU . The proposal uses a single-chip puter AT89 C51 as the Master Control chip. The hardware system makes upof the clock chip DS1302, temperature sensor DS18B20 , buttons, LCD display modules. Hardware system has f ive 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 soon. 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. 目录摘要.................................................................................................................................
