单片机

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、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.
