The digital stopwatch using C language development, digital display timing results. The system hardware and software design, Proteus and Keil software development platform, digital stopwatch simulation. The simulation results show that the digital stopwatch high precision and stability. Today, puter technology has brought major leap in scientific research and production, microputer applications have penetrated into the production, and all aspects of life. Singlechip microputer has a small size, low price, strong features, with improving performance, its scope of increasing width, occupies an important position in the field of puter applications. The stopwatch used in the time we live, work, sports. The stopwatch digitization has brought great convenience to the people39。s production and living, and greatly expanded the original stopwatch function. Development by the beginning of mechanical stopwatch digital stopwatch to the monly used today. The the stopwatch timing accuracy is higher and higher, more and more powerful, increasingly plex structure. In this paper, a singlechip puter, a design based on AT89C52 digital stopwatch, and Proteus and Keil software simulation.Keywords: digital stopwatch。 SCM。 simulationIII目 錄1 設(shè)計(jì)課題任務(wù)、功能要求說(shuō)明及總體方案介紹1 設(shè)計(jì)課題任務(wù)1 功能要求說(shuō)明1 設(shè)計(jì)課題總體方案介紹及工作原理說(shuō)明12 硬件系統(tǒng)的設(shè)計(jì)3 硬件系統(tǒng)各模塊功能簡(jiǎn)要介紹3 電路原理圖、PCB圖、元器件布局圖5 元器件清單53 軟件系統(tǒng)的設(shè)計(jì)18
