用Proteus仿真实现数字钟 要求秒表显示时分秒。 支持秒表基本控制，启动，停止，复位 用Keil C51编程实现上述功能 用Keil与Proteus联调 -Proteus simulation is used to implement digital clock Ask a stopwatch shows minutes. Support a stopwatch basic control, start, stop, reset Use Keil C51 pr

AVR单片机秒表，用PROTUES仿真，一秒一秒的加，直到999为止-AVR microcontroller stopwatch with PROTUES simulation, one second plus one second until the 999 so far

基于proteus 的用51单片机做的秒表 ，有源程序以及仿真程序，直接下载可用-Proteus based on 51 SCM done with a stopwatch, have the source code and simulation program, downloaded directly available
