本人想做一个51单片机的LED点阵显示，怎么从单片机调用所有汉字

1、选一个带汉字库的LED，直接写汉字内码就可以显示汉字了，应该最方便。

2、将国标汉字库转换成LED的汉子库，转换软件可以从供应商求取，也可以自己编一个小程序自己生成。从网上找也可以，很多很多。

#include"at89x51h"

unsigned char code led[]={0x10,0x04,0x10,0x03,0xD0,

0x00,0xFF,0xFF,0x90,0x00,

0x18,0x1D,0xF7,0x13,0x14,

0x00,0x00};

unsigned char i=0,j=0,time_50ms=0;

delay();

你好！！

改了你的程序，还有一个警告，是来自你程序的嵌套了，你在优化一下吧；

代码发给你，主要是修改了fun函数的声明部分：

#define char unsigned char

#define int unsigned int

sbit f0=P1^0;

sbit f1=P1^1;

sbit f2=P1^2;

sbit f3=P1^3;

sbit f4=P1^4;

char key,keytmp();

char code distaba[]=

{0xfd,0xae,0xff,0xae,0xfd,0x06,0xff,0x40,

0xf5,0xb5,0xbf,0xb5,0xf5,0x8a,0x7f,0x2a,

0x20,0xe9,0x8e,0x8e,0xe9,0x22,0x7f,0xa0,

0x10,0x10,0xff,0x10,0x10,0x02,0x7f,0xa0,

0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,

};

char code scan_cona [8]=

{0xfe,0xfd,0xfb,0xf7,0xef,0xdf,0xbf,0x7f};//列扫描控制字

void fun();

//按键扫描函数//   

  void keyscan()   

   {          

    if(f0==0)    

      { 

  while(1) 

  {

  fun(); 

  }   

 }    }

//1ms延时子程序

void delay1ms(int t)

{

int i,j;

for(i=0;i<t;i++)

for(j=0;j<120;j++);

keyscan();

}

//向右滚动显示

void fun()

{

int m,n,h;

  for(h=0;h<32;h++)//控制显示字数（32/8＝4个）

{for(n=0;n<25;n++)//控制帧移动速度

{for(m=0;m<8;m++)//显示1帧扫描（分8行，每行亮1ms)

{P2=scan_cona[7-m];P0=distaba[m+h];delay1ms(1);}

}

}

}

//主程序  

   main()   

    {      

P0=0XFF;

P1=0XFF;

P2=0XFF;

P3=0XFF;

while(1)

  { fun();}

 }

我也不怎么会，还在学习中

下面有一个1616的C程序

参考一下。。。

字模软件你要的话我可以给你

共同学习。。。
