Windows环境下利用多线程技术实现计算机与单片机的串行口通讯

Realize serial port communication between PC and singlechip microcomputer in windows by using multi-thread technology

基于 3 2位Windows98环境开发了计算机与单片机间进行串行口通讯的软硬件系统 ,其中采用了多线程技术模拟中断机制 ,并利用同步事件确保线程间资源共享的同步 ,从而有效地克服了传统串行口通讯中的迟滞性和不可靠性。

A software and hardware system that realizes the serial port communication between PC and singlechip microcomputer in 32bit Windows98 operating system was develped. In order to overcome the problem of sluggish and fallibility in traditional serial port communication, Multi Thread technology is used in the system to simulate the interrupt functionality, and synchronize event object is also applied to synchronize the share resources among different threads.
