文档介绍：ABOUT SCM
It can be said across the twentieth century, the three "electric" era, that is, electrical era, the electronic age, and has now entered puter age. However, such puter, usually refers to the puter, referred to as PC. It consists of the host, keyboard, monitor etc.. Another type puter, most people do not know how. puter is to smart to give a variety of mechanical microcontroller (also known as micro-controller). As the name suggests, puter system only used the smallest one IC, you can perform simple operations and control. Because of its small size, usually hidden in a charged mechanical "stomach" Lane. It is the entire device, like the human brain plays a role, it goes wrong, the whole device was paralyzed.
Now, this MCU has a very wide field of use, such as smart meters, real-time industrial control, communications equipment, navigation systems, home appliances and so on. Once the microcontroller were using a variety of products, you can serve to upgrade the effectiveness of the product, often in the product name is preceded by the adjective - "smart", such as washing machines and so intelligent. At present, some technical personnel of factories or other amateur electronics developers to engage in out of certain products, not the circuit is plex, that is, functions are too simple and easy to be copied. The reason may be stuck in the product without the use of a mic
