基于单片机的多功能数字万年历的设计 摘 要 随着电子技术的迅速发展，特别是大规模集成电路出现，新一代电子产品给人类生活带来了根本性的改变。尤其是单片机技术的应用产品已经走进了千家万户，而数字万年历的出现给人们的生活带来的诸多方便。 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过程。本设计以数字集成电路技术为基础，单片机技术为核心。本文编写的主导思想是软硬件相结合，在硬件基础上来进行软件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，增加了程序的可读性和可移植性，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更加简洁明了。系统通过点阵式液晶为载体显示数据，所以具有人性化的操作和美观的页面效果，可以显示时间、公农历日期、星期、温度、节气，天干地支，并有闹铃功能。关键词 单片机；万年历； 液晶技术 ； 农历Design of Multifunctional digital Perpetual Calendar Based on MCU Abstract With the rapid development of electronic technology， especially with the emergence of large-scale integrated circuits， a new generation of electronic products has brought about a fundamental change to our human beings. In particular， products based on Microcontroller single-chip technology have entered tens of thousands of households and the emergence of digital calendar have brought about a lot of convenience to peoples lives. his article will first describe the working principle of the hardware system with the system block diagram to illustrate the structure， and highlighted by the application of the system interface technology of the hardware and the interface module functions and work processes. Secondly， I described the program in detail and how I did it. The design is based on digital integrated circuits technology， with single-chip technology as the core. The essence of this article is the combination of the hardware and the software. We proceed programming based on hardware.The system uses C-language software programming， which increases the readability and portability. In order to facilitate the expansion and changes to the design of modular software structure， the design of the software adopts module programming which made the logic of the program is more concise. The system adopts the vector dot-matrix liquid crystal to display data and therefore have a user-friendly operation and aesthetically pleasing results， which can show the time， the Chinese date， w
