利用MFC实现Windows下工业控制的高精度定时

Implementation of High-performance Timer Applied to Industrial Control under Windows System by Use of MFC

Windows9x系统下的高精度定时器的设计一直是实现高速控制和采集的关键技术。本文分析了Windows的普通API定时函数的局限性,提出了一种利用MFC实现在Windows9x系统下高精度定时的新方法。

The design of high-performance timer under windows system is always the key technology to implement the high speed control and sampling.The paper analyzes the limitation of normal windows API functions,and propose s a new method to implement it by use of MFC.
