当前,单板机在数据采集和处理,以及自动控制中得到普遍应用。随着大规模集成电路技术的发展,单板机的基本结构已能够集成在一片芯片上,即所谓单片微型计算机,简称单片机。由于单片机价格低廉、结构紧凑、功能完善、功耗低等优越特性,在国外获得了广泛应用。近几年来,国内在智能 Currently, the single board machine in data acquisition and processing, and automatic control has been widely used. With the development of large-scale integrated circuit technology, the basic structure of single-board machine has been able to integrate in a chip, the so-called single-chip microcomputer, referred to as single-chip. Because of its low cost, compact structure, perfect function and low power consumption, it has been widely used abroad. In recent years, the domestic intelligence
