范文编号:JD1157 范文字数:14828,页数:43 附任务书 随着电子产品向智能化和微型化的不断发展,单片机已经成为电子产品研制和开发中首选的控制器。单片机即单片微型计算机(Single-Chip-Microcomputer),是集CPU、RAM、ROM、定时、计数和多种接口于一体的微控制器。其中51/52是由各种单片机中具有代表性的,广泛运用于各个领域。为了更好的推广在公共领域的运用,本文介绍一种应用AT89S52单片机设计的自动打铃系统,经实际制作表明该系统具有时间的校准及设定等等的作用,符合学校打铃的要求,具有一定的实际意义。 关键词:AT89S52; I2C总线 ;AT24C02 ; DS1302; LCD1602; ABSYTACT As lectronic products to intelligence and the continuousdevelopmentof miniaturization, SCM has become the research and development of electronic product first controller. SCM (Single Chip computer is Chip Microcomputer - - your CPU, is set to), ROM, RAM, timing, counting and multiple interfaces in one of the micro controller. One is by all sorts of 51 SCM / 52 the representative, is widely used in various fields. In order to promote the use of public domain in an application,this paper introduces the design of automatic AT89S52 SCM system, theactual production bell that this system has the time of calibration andsetting, etc, accord with the request, ringing school has certain practical significance. 目录 摘要…………………………………………………………………………………I 基于单片机的打铃系统相关范文 |
