在做项目（工程）的时候，我们经常要用到比较多的按键，而且IO 资源紧张， 于是我们就想方设法地在别的模块中节省IO 口，好不容易挤出一两个IO 口，却 发现仍然不够用，实在没办法了就添加一个IC 来扫键。一个IC 虽然价格不高， 但对于大批量生产而且产品利润低的厂家来说，这是一笔不菲的开支! 那，我们能不能想到比较好的扫键方法：用最少的IO 口，扫最多的键？可以吗？-Doing the project (engineering), we often use the relatively large number of keys, and the IO resource constraints, so we are trying to save in another module IO ports, finally out of one or two IO ports, only to find is still not enough there is really no other way to add an IC to sweep on the keys. Although the price of an IC is not high, but low profits, high-volume production and product manufacturers, this is spending a lot of money! That, we can not think of a better scan key method: with a minimum of IO ports, scan Most of the keys? OK?

C51强大功能及其高效率的重要体现之一在于其丰富的可直接调用的库函数，多使用库函数使程序代码简单，结构清晰，易于调试和维护，下面介绍C51的库函数系统。-C51 powerful features and its high efficiency in one important manifestation of its rich can directly call the library, multi-use library functions to make the code simple, clear and easy to debug and maintenance, and C51 introduced below the library system.

该程序设计采用2051进行控制,原理比较简单.但是要完全调试成功比较麻烦!我自己已经调试差不多了,祝大家都可以掌握基本控制理论!-procedures designed using the 2051 control, principle is relatively simple. However, to successfully complete debugging more trouble! I have been debugging almost wish you could grasp the basic control theory!
