1、 毕业设计论文 题 目:基于 MCS-51 的万年历设计 院 系: 专 业: 姓 名: 指导老师: I 摘摘 要要 本设计是一个基于 MCS-51 单片机实现的万年历。 本文首先描述系统硬件工作原理,并附以系统结构框图加以说明,着重介绍了本 系统所应用的各硬件接口技术和各个接口模块的功能及工作过程,其次, 详细阐述了程 序的各个模块和实现方法。本设计以数字集成电路技术为基础,AT89C51 单片机技术 为核心。本文编写的主导思想是软、硬件相结合,以硬件为基础,来进行各功能模块 的编写。 本系统以单片机的 C 语言进行软件设计,为了便于扩展和更改,软件的设计采用 模块化结构,使程序设计的逻辑关系
2、更加简洁明了。系统通过字符型液晶显示数据, 所以具有人性化的操作和直观的显示效果。可以显示时间、公历日期、星期,并有闹 铃、语音报时及检测温度的功能。 关键词关键词: 单片机; 液晶模块 ;语音报时;温度传感器; II Abstract The design is a based on the MCS-51 perpetual calendar. This article first describes the system hardware principle of work,and attaches by the system structure diagram performs to e
3、xplain,emphatically introduced this system applies various hardware connection technology and each interface module function and the workprocess, next, it is elaborated the procedure of each module and how they realized. This design is based on the digital IC, and the core of AT89C51 MCU technique.
4、This article writed with the guiding of software and hardware unifies, take the hardware as thefoundation, writing each programme for each functions module. This systems software design whth the MCU C language, in order to be advantageous for theexpansion and change, the software design uses the design of modularization, so that the logical of the programmer become clear and it is easy to understand .This system use the characte
