基于12864的模拟电子钟-单片机课程设计.doc

《单片机技术》课程设计说明书 基于12864的模拟电子钟 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，单片机都起到了举足轻重的作用。 所以单片机技术也日趋成熟。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。而52系列单片机是各单片机中最为典型和最有代表性的一种。 此次单片机课程设计是通过利用52单片机来完成对电子钟的设计，且由12864液晶显示屏来显示时钟信息，并带有DS18B20输出的实时温度显示。此次课程设计达到了学习、了解单片机相关指令在各方面的应用，以及初步了解开发软、硬件的知识。 关键词 ：单片机；12864液晶屏；DS18B20；实时温度 ABSTRACT MCU application technology rapid development throughout all areas of life we are now, the missile from the navigation device to control a variety of instruments on the plane, network communications and data transfer from the computer to the real-time control and data processing industrial automation process, and we live in a variety of widely used smart IC cards, electronic pets, MCU have played a pivotal role. So microcontroller technology matures. MCU is a set of CPU, RAM, ROM, timing, counting, and multiple interfaces in one microcontroller. Its small size, low cost, high functionality. The 52 Series single-chip microcontroller is all the most typical and most representative one. The course is designed by the use of single-chip microcontroller 52 to complete the electronic clock design, and the 12864 LCD screen to display the clock information and real-time temperature display with DS18B20 output. The curriculum designed to meet the learning and understanding of MCU-related instruction in all aspects of the application, as well as a preliminary understanding of the development of software and hardware knowledge. Key words MCU; 12864 LCD screen; DS18B20; real-time temperature 目录 TOC \o 1-3 \h \z \u HYPERLINK \l _Toc375670845 第一章 绪论 PAGEREF _Toc375670845 \h - 1 - HYPERLINK \l _Toc375670846 1.1 12864液晶显示概述 PAGEREF _Toc375670846 \h - 1 - HYPERLINK \l _Toc375670847 1.2 12864的特点 PAGEREF _Toc375670847 \h - 1 - HYPERLINK \l _Toc375670848 1.3 12864液晶的工作原理 PAGEREF _Toc375670848 \h - 1 - HYPERLINK \l _Toc375670849 1.4 基于单片机控制液晶显示系统的设计任务摘要 P
