介绍了以8051(CMOS低功耗)单片机为核心元件,并配以微功耗LED显示屏和串并行转换芯片及其他低功耗集成芯片,组合成的秒表系统。与普通秒表相比,除了带有计时暂停功能以外,增加了自设初始值的功能。其突出的优点:体积小、场外作业、功耗最低、宜用电池作为电源、硬件结构紧凑、简单和软件设计灵活。

-Introduced in 8051 (CMOS low-power) microcontroller as the core element, and with a micro-power LED display and serial to parallel conversion chips and other low-power integrated chip, a combination stopwatch system. Compared with ordinary stopwatch, timer with the pause function in addition, increases from an initial value setting function. Its outstanding advantages: small, off the job, lowest power, to use the battery as a power source, a compact hardware architecture, software design is simple and flexible.
