Single-Chip Microcomputer有的时候，也可以用SingleChip来代替下面链接的第六章有讲单片机Single Chip Microcmputer 第148页开始这是一段中汉对照的。中文:单片机是把主要计算机功能部件都集成在一块芯片上的微型计算机。它是一种集计数和多中接口于一体的微控制器，被广泛应用在智能产品和工业自动化上，而51单片机是个单片机中最为典型和最有代表性的一种。本课题选择89S51为核心控制元件，设计了一个日常生活中用到的电子音乐门铃系统。当功能按键按下，音乐响起，发光二极管随着音乐的节拍进行闪烁，LED显示相应的定时器初值。音乐演奏过程中再次按下按键无效，只有当音乐段结束再次按下才有效。如果是电子音乐门铃在响，按下复位按键就终止，显示初始状态。经过实践证明，本系统运行稳定，具有一定的实用价值。-------------翻译:SCM is a major piece of computer components are integrated into the chip micro-computer. It is a multi-interface and counting on the micro-controller integration, and intelligence products are widely used in industrial automation. and MCS-51 microcontroller is a typical and representative.The topics chosen for the 89S51 control of the core components used in the design of a daily electronic music doorbell system. When the function button is pressed, the music sounded and the music beats with light emitting diodes for flickered. Initial corresponding LED timer. Musical process again pressed the button ineffective, and only when pressed again before the end of the music effectively. If the doorbell ring for electronic music, press the button on the reduction and termination, showed initial state. Practice has proved that the system is stable and has some practical value.本设计是以凌阳16位单片机为重心，介绍语音控制在机械手中的应用，实现微型舵机的运作，完成所指定的动作。其中通过凌阳16位单片机输出的脉冲信号来准确的控制机械手的摆动角度，机械手的捏拿动作由电磁铁完成，电磁铁的通断由凌阳16位单片机的I/O口控制，硬件和软件都在具体的实验中证明了其可行性This design is take insults the positive 16 monolithic integrated circuits as a center of gravity, introduced the pronunciation control in manipulator's application, the realization miniature servo operation, completes the movement which assigns. Through insults the pulse signal which the positive 16 monolithic integrated circuits outputs to come the accurate control manipulator to swing the angle, the manipulator pinches takes the movement to complete by the electro-magnet, the electro-magnet passes the legal reason for judgment to insult the positive 16 monolithic integrated circuits I/O control, the hardware and the software all have proven its feasibility in the concrete experiment
单片机又称单片微控制器,它不是完成某一个逻辑功能的芯片,而是把一个计算机系统集成到一个芯片上。相当于一个微型的计算机，和计算机相比，单片机只缺少了I/O设备。概括的讲：一块芯片就成了一台计算机。它的体积小、质量轻、价格便宜、为学习、应用和开发提供了便利条件。同时，学习使用单片机是了解计算机原理与结构的最佳选择。SCM is also known as single chip microcontroller, it is not complete a certain logic function of the chip, but a computer system integrated into a chip. The equivalent of a microcomputer, and compared to the computer, the single chip is only a lack of I/O equipment. Generally speaking: a chip has become a computer. Its small size, light weight, cheap, for the study, application and development provides a convenient condition. At the same time, learning to use the MCU is the best choice to understand the principle and structure of the computer.单片机的使用领域已十分广泛，如智能仪表、实时工控、通讯设备、导航系统、家用电器等。各种产品一旦用上了单片机，就能起到使产品升级换代的功效，常在产品名称前冠以形容词——“智能型”，如智能型洗衣机等SCM has a very wide range of applications, such as intelligent instruments, real-time industrial control, communications equipment, navigation systems, household appliances, etc.. Once a variety of products with the use of a single chip, you can play the product to upgrade the effectiveness, often in the product name preceded by the adjective - "intelligent", such as intelligent washing machines, etc.
