Description: 该程序实现独立按键去控制 LED灯 的亮灭，并讲叙了对按键的处理方法。 独立按键相应的IO口平时为高电平，一旦按键按下，单片机便检测到低电平。-The program implements the independent button to control the LED lights off, and spoke of the right key approach. Independent buttons corresponding IO port usually is high, once the button is pressed, the microcontroller will detect low.

Description: * 1) 按键状态说明：
* 按键采用查询方式判断，每检测一次将以前状态向左移动一位并记录最新检测状态。
* 按键状态只取低三位：
* 000 - 没有检测到按键动作
* 001 - 第一次检测到按键动作
* 011 - 按键稳定闭合
* 111 - 按键持续闭合
* 110 - 第一次检测到按键释放
* 100 - 按键稳定释放
* 010 - 正脉冲抖动干扰,状态置为 000
* 101 - 负脉冲抖动干扰,状态置为 -* 1) Key Status Description:* keys using queries judgments, each will be tested once left a previous state and record the latest detection status.* Low-key status only take three:* 000- did not detect keystrokes to 001- first detected keystroke* 011-* 111 keys stable closure- Button continued closed* 110- first detected key released* 100- Button stable release* 010- positive pulse jitter interference, the state is set to 000* 101- Negative pulse jitter interference, the state is set to 111

Description: 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!-very good key scan
