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
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！
#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)
{

P2_4=1;
P2_3=1;

}
void main()
{
Nixie(2,5);
while(1)
{}
}

好啦，静态数码管显示和动态数码管显示的内容就到这里啦，还要继续加油！！！
