湖北工业大学商贸学院毕业设计 PAGE  PAGE \* MERGEFORMATIV 摘 要 单片机应用技术飞速发展，纵观我们现在生活的各个领域，从导弹的导航装置，到飞机上各种仪表的控制，从计算机的网络通讯与数据传输，到工业自动化过程的实时控制和数据处理，以及我们生活中广泛使用的各种智能IC 卡、电子宠物等，这些都离不开单片机。单片机是集CPU ,RAM ,ROM ,定时，计数和多种接口于一体的微控制器。它体积小，成本低，功能强，广泛应用于智能产业和工业自动化上。 本设计着重要描述的就是基于AT89S52的单片机的电子万年历。本文首先描述系统硬件工作原理，随后说明了本系统所应用的各硬件接口技术（既芯片驱动程序）和各个接口模块的功能及工作过程。本设计的主导思想是软硬件相结合来进行各功能模块的编写。 电子万年历以硬件C语言为主体进行软件设计，增加了程序的可读性和可移植性。系统通过LCD液晶输出显示数据，可以显示当前时间、公农历日期、星期、温度，并附有以峰鸣器为提示的闹铃功能。 关键词：单片机 电子万年历 公农历 接口模块 C语言 Abstract MCU rapid development of applied technology, we now live Looking at the various fields, from the missiles navigation devices, to the various instruments on the aircraft control, computer network communications and data transmission, industrial automation to the process of real-time control and data Processing, and we live in the extensive use of the smart IC cards, electronic pets, these are inseparable from the SCM. SCM is set CPU, RAM, ROM, timing, counting on one interface and a variety of microcontrollers.Its small size, low cost, feature strong, smart widely used in industry and industrial automation. This design is going to describing the calendar based on AT89S52. System hardware of main body is described first, Follow the function, principle of work and hardware interface (that means the chip’s drives) are introduced. The design‘s main ideas is that composes soft and hardware to achieve the design. The calendar is designed with hardware C language as the Realization tool, which increased procedure readability and transplanting. The system shows the output by LCD1602, which can demonstrate the current time, the lunar calendar date, the week, the temperature and the system, can alter people with a small sounder. Keywords: MCU Electronic calendar Lunar calendar Interface module C Language. 目 录 TOC \o 1-3 \h \z \u   HYPERLINK \l _Toc294969476 摘 要  PAGEREF _Toc294969476 \h I  HYPERLINK \l _Toc294969477 Abstract  PAGEREF _Toc294969477 \h II  HYPERLINK \l _Toc
