静态数码管显示+动态数码管显示——“51单片机”

各位CSDN的uu们好呀，今天小雅兰的内容还是51单片机的知识，是为静态数码管显示和动态数码管显示，下面，让我们进入51单片机的世界吧！！！

静态数码管显示

动态数码管显示

源代码

静态数码管显示

首先，我们得知道，数码管是一个什么样的东西：

它就是51单片机最上面的那个看起来像显示屏的东西，断开电源的时候，是八个八的样式！！！

然后这边还有C语言的一些小知识点：

了解了上面这些知识之后，就可以开始来写一个我们的代码了！

cpp 复制代码

#include <REGX52.H>

unsigned char NixieTable[]={0x3F,0x06,0x5B,0x4F,0x66,0x6D,0x7D,0x07,0x7F,0x6F};
void Nixie(unsigned char Location,unsigned char Number)
{
	switch(Location)
	{
	case 1:
		P2_4=1;
		P2_3=1;
		P2_2=1;
		break;
	case 2:
		P2_4=1;
		P2_3=1;
		P2_2=0;
		break;
	case 3:
		P2_4=1;
		P2_3=0;
		P2_2=1;
		break;
	case 4:
		P2_4=1;
		P2_3=0;
		P2_2=0;
		break;
	case 5:
		P2_4=0;
		P2_3=1;
		P2_2=1;
		break;
	case 6:
		P2_4=0;
		P2_3=1;
		P2_2=0;
		break;
	case 7:
		P2_4=0;
		P2_3=0;
		P2_2=1;
		break;
	case 8:
		P2_4=0;
		P2_3=0;
		P2_2=0;
		break;
	}
	P0=NixieTable[Number];
}
void main()
{
	Nixie(7,8);
	while(1)
	{}
}

修改一下Nixie的参数，就能改变数码管显示的数字和位置。

#include <REGX52.H>

unsigned char NixieTable[]={0x3F,0x06,0x5B,0x4F,0x66,0x6D,0x7D,0x07,0x7F,0x6F};
void Nixie(unsigned char Location,unsigned char Number)
{
switch(Location)
{
case 1:
P2_4=1;
P2_3=1;
P2_2=1;
break;
case 2:
P2_4=1;
P2_3=1;
P2_2=0;
break;
case 3:
P2_4=1;
P2_3=0;
P2_2=1;
break;
case 4:
P2_4=1;
P2_3=0;
P2_2=0;
break;
case 5:
P2_4=0;
P2_3=1;
P2_2=1;
break;
case 6:
P2_4=0;
P2_3=1;
P2_2=0;
break;
case 7:
P2_4=0;
P2_3=0;
P2_2=1;
break;
case 8:
P2_4=0;
P2_3=0;
P2_2=0;
break;
}
P0=NixieTable[Number];
}
void main()
{
Nixie(2,5);
while(1)
{}
}

动态数码管显示

		} while (--i);
		xms--;
	}
}

void Nixie(unsigned char Location,unsigned char Number)
{

	{
