在许多c程序设计中，要用到汉字进行提示或人机交互，而现行的turbo c集成开发环境不是汉化的，如何编制能显示汉字的c程序呢？
下面的方法可以帮你在西文环境下显示汉字。这种方法是调用中文汉字库进行汉字显示。国家标准规定：汉字库分94个区，每个区有94个汉字（以位作区别），每个汉字在汉字库中有确定的区和位编号，这就是汉字的区位码。每个汉字在库中是以点阵字模形式存储的，一般采用16×16点阵（32字节）、24×24点阵（72字节），每个点用一个二进制位（0或1）表示，对应在屏幕上显示出来，就是相应的汉字。
由于在中文环境下，输入的是汉字的内码，我们必须将之转换成区位码，算出偏移量，从字库中找到对应的汉字，将其字模显示即可。
内码转换成区位码方法如下：
qh=c1－0xa0 wh=c2－0xa0
其区位码就是：
qw=qh＊0xff＋wh
该汉字在字库中离起点的位置是：
offset=(94＊(qh－1）＋(wh－1))＊32l
程序例：
＃include 〈graphicsh〉
＃include 〈stdioh〉
＃include 〈fcntlh〉
＃include 〈ioh〉
＃include 〈stdlibh〉
＃include 〈conioh〉
＃define row 1 //纵坐标放大倍数
＃define col 2 //横坐标放大倍数
void main()
{
int x,y;
char ＊s=″汉字显示程序″;
file ＊fp;
char buffer[32]; //buffer用来存储一个汉字
register m,n,i,j,k;
unsigned char qh,wh;
unsigned long offset;
int gd=detect,gm; //图形屏幕初始化
initgraph(＆gd,＆gm,″ ″);
if ((fp=fopen(″hzk16″,″rb″))==null)
//打开汉字库，该字库可以在ucdos中找到
{ printf(″can't open haz16,please add it″);
getch(); closegraph(); exit(0);
}
x=20; y=100; //显示位置设置
while(＊s)
{ qh=＊(s)－0xa0; //汉字区位码
wh=＊(s＋1)－0xa0;
offset=(94＊(qh－1)＋(wh－1))＊32l; //计算该汉字在字库中偏移量
fseek(fp,offset,seek_set);
fread(buffer,32,1,fp); //取出汉字32字节的点阵字模存入buffer中（一个汉字）
for (i=0;i〈16;i＋＋) //将32位字节的点阵按位在屏幕上打印出来(1:打印,0:不打印),显示汉字
for(n=0;n〈row;n＋＋)
for(j=0;j〈2;j＋＋)
for(k=0;k〈8;k＋＋)
for(m=0;m〈col;m＋＋)
if (((buffer[i＊2＋j]〉〉(7－k))＆0x1)!=null)
putpixel(x＋8＊j＊col＋k＊col＋m,y＋i＊row＋n,green);
s＋=2; //因为一个汉字内码占用两个字节,所以s必须加2
x＋=30;
}
getch();
closegraph();
}
上述程序在turbo c 20编译系统下运行成功，它可以将汉字放大显示，读者可以将它改成函数用在您的程序中显示汉字。

给你个方向
先搞清楚数码管是如何显示指定数据的，再看看矩阵键盘的电路和处理方式，结合两者的理解就可以处理你的LED矩阵显示啦。至于程序怎么写，如果搞清楚我说的数码管和矩阵键盘的知识和范例都不会，那给你程序也没什么意义啦。
这个就看你怎么应用了。假设你想用它来显示一个汉字。你想一下，88的点阵只可以显示简单的汉字，复杂的汉字就只能用更大的点阵了。更大的点阵表现力就更加丰富了。功能不多加叙述。
至于程序，其实还要结合电路。即点阵中有许多发光二极管，行列谁对应高，低电平，要清楚。单片机肯定带不动这个电路，故还有驱动电路。结合以上信息才能定义管脚。
