<h1><center><strong>实验二 利用8255A实现LED的流水点亮实验</strong></center></h1>
|
||||
|
||||
### 一、实验目的
|
||||
|
||||
该实验的目的在于掌握8255A和微机接口的连接方法，了解8255A的基本的工作原理和编程方法。
|
||||
|
||||
### 二、实验内容
|
||||
|
||||
**任务一：**PA口接8个拨动开关K1-K8，PB口接8个LED。初始由开关K1-K8设定8位不同的值，当执行程序后LED按K1-K8初始设定的值点亮，并向右流动（8255A工作在0方式）。
|
||||
|
||||
**任务二：**在数码管上显示“8255-A”。
|
||||
|
||||
### 三、流程图
|
||||
|
||||
**任务一：**
|
||||
|
||||
|
||||
|
||||
**任务二：**
|
||||
|
||||
|
||||
|
||||
### 四、实验过程与分析
|
||||
|
||||
**任务一：**
|
||||
|
||||
首先在实验箱中将接线连好。将8255A芯片的CS连到280H地址。因此命令口为283H，PA口为280H，PB口为281H，PC口为282H。
|
||||
|
||||
将PA口连到开关上，PB口连到LED灯上。
|
||||
|
||||
然后设置好开关。将代码编译后运行。运行效果如视频所示。
|
||||
|
||||
**任务二：**
|
||||
|
||||
首先在实验箱中将接线连好。将8255A芯片的CS连到280H地址。将PA口连到位码接口上，PB口连到段码接口上。
|
||||
|
||||
<img src="task2.jpg" alt="task2" style="zoom:25%;" />
|
||||
|
||||
将代码编译后运行。运行效果如图所示。
|
||||
|
||||
### 五、实验总结
|
||||
|
||||
在本实验中，我掌握了8255A和微机接口的连接方法，了解了8255A的基本的工作原理和编程方法，收获颇丰。
|
||||
|
||||
### 六、思考题
|
||||
|
||||
> 在本实验的硬件电路中，能使用C口对LED指示灯控制码？如果可以写出2种控制方法（编程方法）。
|
||||
|
||||
**控制方法一：**使用命令口直接将PC口置位。
|
||||
|
||||
```assembly
|
||||
MOV DX, 283H ; 设置命令口
|
||||
MOV AL, 00000101B ; 0|xxx|010(指定PC2引脚)|1(置位)
|
||||
OUT DX, AL ; 输出
|
||||
```
|
||||
|
||||
**控制方法二：**使用方式0，将PC口置为数据输出口。
|
||||
|
||||
```assembly
|
||||
MOV DX, 283H
|
||||
MOV AL, 10000000B ; 1|00(A组0方式)|0(PA输入)|0(PC4-7输出)|0(B组0方式)|0(PB输出)|0(PC0-3输出)
|
||||
OUT DX, AL
|
||||
|
||||
MOV DX, 282H
|
||||
MOV AL, 00000001B ; PC1为高电平
|
||||
OUT DX, AL
|
||||
```
|
||||
|
||||
