# 流水灯

## sbit 变量名=地址值；  在给某个引脚取名的时候经常会用到。

## typedef使用

`typedef unsigned char u8;`

`typedef unsigned int u16;（后面要加分号）`

## define使用

`define A P0(注意后面不用加分号)`

# 蜂鸣器

* I/O端口默认都是高电平

## 数码管(静态，动态)

* 位选，3-8译码器

```

sbit LSA=P2^2;			 //三八译码器

sbit LSB=P2^3;

sbit LSC=P2^4;

```

## 独立按键

* P3^1，P是大写

* 消除抖动 一般大约10ms
