keilc51编译的51单片机读条码枪源程序

采用定时器中断的方法，设计一个一天24小时进制的实时时钟；用6个发光二极管分别显示时、分、秒的记时； 能进行整点报时。可以从键盘中预置、修改时钟值。含有硬件设计图-timer interruption using the method to design a band 24 hours a day in real-time clock; With six light-emitting diodes showed the hours, minutes, and seconds to the entry; Can the entire point timekeeping. Which can be preset from the keyboard, the revised value of the clock. Containing the hardware design

频率计 等精度频率计 可以用于频率测试的等精度频率计 可用的-Such as precision frequency meter frequency meter can be used for the frequency of tests, such as precision frequency meter available

我觉得挺有用的东西-the things
