在工业控制计算机的应用中 ,利用串行方式实现I/O端口的扩展和数据通信不失为改善系统的效能和降低成本的一个较好的方法 .提出了一种简单的通信电路 ,不需要使用± 15V电源和电平转换即可实现微机与单片机之间的通信 ,并介绍和分析了多线程在数据处理中的应用 . In industrial control computer applications, the use of serial I / O port expansion and data communication is a better way to improve system performance and reduce costs.A simple communication circuit is proposed, without using ± 15V power and level conversion can be achieved between the microcomputer and the microcontroller communication, and introduced and analyzed the multi-threaded data processing applications.
