摘要介绍了在一个监测或监控系统中使用多个单片机时,单片机之间的数据交换方法。重点阐述了双单片机之间数据交换的双向平行、单向平行、串行、并转串或串转平等数据交换方式,并从硬件和软件两个方面分析了保证数据交换准确性而采取的抗干扰措施。 关键词 系统 多单片机 数据交换方法 Abstract The method of data exchange among multiple single chip computers in one measuring or monitoring system is introduced. The Schemes of data exchange between two single chip computers,e. g. ,bi-directional parallel,single directional parallel ,seriral,parallel to serial,or serial to parallel,etc. are described emphatically. The measures of anti-interference to ensure precise data exchange are analyzed from both hardware and software aspects. Keywords System Multiple single chip computers Data exchange Method
