数字钟是一种用数字电路技术实现时、分、秒计时的装置，与机械式时钟相比具有更高的准确性和直观性，且无机械装置，具有更更长的使用寿命，因此得到了广泛的使用。数字钟从原理上讲是一种典型的数字电路，其中包括了组合逻辑电路和时序电路。目前，数字钟的功能越来越强，并且有多种专门的大规模集成电路可供选择-Digital Clock is a digital circuit technology with the hours, minutes, seconds, timing devices, as compared with the mechanical clock has a higher accuracy and intuitive, and no mechanical devices, with more longer life, so be a wide range of use. Digital clock from the principle of speaking, is a typical digital circuits, including combinational logic circuits and sequential circuits. At present, the digital clock and more powerful, and there are a variety of specialized large scale integrated circuits to choose from

使用89S52为核心做的USB键盘,注意修改了一下windows设备描述符以及端点处理等就行了。用了一个4*4的小键盘,有0-9十个数字键, Num Lock键,Caps Lock键,Shift键,Ctrl键,Alt键,回车键等。 最多可以有三个键同时按下，如果相交的话，最多只能两个键按下-89S52 use as the core of the USB keyboard to do, pay attention to modify the look and the windows device descriptor, such as treatment endpoint on the list. Used a 4* 4 small keyboard, has the number keys 0-9 10, Num Lock keys, Caps Lock key, Shift key, Ctrl key, Alt key, enter key and so on. Can have up to three keys pressed at the same time, if the intersection, then a maximum of only two keys pressed
