一、前言 在微型计算机大发展的时代,单片微型计算机作为微型机范畴的一个分支,异军突起,发展毫不逊色。 单片微型计算机(简称:单片机)是继微处理器之后发展起来的新型大规模集成电路。它在一块芯片上集成了中央处理单元(CPU)、存贮器(RAM或ROM/EPROM)、输入/输出口(I/O)三大基本功能部件以及有关的其他功能部件。这块芯片就是一个最基本的微型计算机。只要给单片机配以适当少量的外围器件,就可实现各种功能要求。由于这种器件是针对工业控制以及与控制有关的数据采
I. Introduction In the era of great development of microcomputers, the single-chip microcomputer, as a branch of the category of minicomputers, has emerged as a meteoric rise and developed no less. Monolithic microcomputer (referred to as: Microcontroller) is a new type of large-scale integrated circuits developed after the microprocessor. It integrates the three basic functions of CPU, memory (RAM or ROM / EPROM), I / O (I / O) and other related functions on a single chip. This chip is one of the most basic microcomputers. As long as the microcontroller with a suitable small amount of peripheral devices, you can achieve a variety of functional requirements. Because of this device is for industrial control and control-related data mining
