点阵字库
一般我们使用16*16的点阵宋体字库，所谓16*16，是每一个汉字在纵、横各16点的区域内显示的。
不过后来又有了HZK12、HZK24，HZK32和HZK48字库及黑体、楷体和隶书字库。
虽然汉字库种类繁多，但都是按照区位的顺序排列的。前一个字节为该汉字的区号，后一个字节为该字的位号。
每一个区记录94个汉字，位号则为该字在该区中的位置。
因此，汉字在汉字库中的具体位置计算公式为：94*(区号-1)+位号-1。
减1是因为数组是以0为开始而区号位号是以1为开始的。
这仅为以汉字为单位该汉字在汉字库中的位置，那么，如何得到以字节为单位得到该汉字在汉字库中的位置呢？
只需乘上一个汉字字模占用的字节数即可，
即：(94*(区号-1)+位号-1)*一个汉字字模占用字节数，而按每种汉字库的汉字大小不同又会得到不同的结果。
以16*16点阵字库为例，计算公式则为：(94*(区号-1)+(位号-1))*32。
汉字库文该从该位置起的32字节信息即记录了该字的字模信息。
了解点阵汉字及汉字库的构成原理后，显示汉字就变得简单。以16*16点阵字库为例，
通常的方法是：将文件工作指针移到需要的汉字字模处、将汉字库文件读入一2*16数组再用for循环一位位地显示。

i=chinease[0]-0xa0;j=chinease[1]-0xa0; /*获得区码与位码*/
fseek(HZK,(94*(i-1)+(j-1))*32l,SEEK_SET);
fread(mat,32,1,HZK);
for(j=0;j<16;j++)
for(i=0;i<2;i++)

‘叁’ 8*8双色点阵怎么用，C语言代码怎么写
1、8*8双色点阵实际上是两个8*8点阵，必须增加一个端口来控制是使用哪个颜色的8*8点阵；或者连接成一个8*16点阵来控制。C语言代码和控制8*8点阵类似，增加扫描端口就可以了。
