摘要:

Visual C++6.0是Window平台下最为流行的编程工具之一.在测控系统中,PC机与各种嵌入式系统之间的接口控制也通常采用VC6.0完成.然而嵌入式系统通常对时序有较高的要求,Windows系统则并非实时操作系统.因此如何在VC6.0中实现各种不同精度的定时功能就成为许多面向嵌入式系统的VC6.0开发关键环节.文中研究和比较了VC6.0平台下各种定时器的用法和性能.根据试验结果,并针对某实际工程需要,采用时间戳计数器实现了一种微秒级定时器.通过测试,该定时器可以实现微秒级高精度定时,与某嵌入式系统平台配合良好,并通过了设备验收,证明了其设计有效性

Abstract:

Visual C++6. 0(VC 6. 0) is one of the most popular development environments for Windows platform. Therefore,most of in-terface control of measurement&control system between embedded system and PC were also developed via VC6. 0. However,since high-precision timing is often necessary for embedded system,and Window operation system (OS) isn't real-time OS. How to design timer to meet different embedded system requirement becomes a vital process for VC 6. 0 development. In this paper,all kinds of timer design strategies were introduced and presented,following with their comparison. Finally,according to one project demand,based on CPU time stamp counter technique,a microsecond-level timer was presented. Whole project has been validated,therefore this times strategy's effect was also proved
