如何利用ASCII表显示ASCII？？（不知程序错在哪？）

程序如下，但是运行显示的ASCII却不正确？请问是偏移地址算的不正确吗？？！还是什么原因呢？！
static GetFontasc (char *asccodes1)
{
      unsigned long offset;
      char *p1;
      p1=asccodes1;
   offset=(*asccodes1)*16;
      ASC=fopen("D:\\ascii","rb");
      fseek(ASC, offset, SEEK_SET);
      fread(FontDataBufasc, 16, 1, ASC);
      fclose(ASC);

}

void Lcd_DispAsc(char *asccodes2)
{
            int i,j,m=0;
          unsigned int data;
          char *p2;
          p2=asccodes2;
          GetFontasc(p2);
          for(j=0;j<16;j++)
          {
              data=FontDataBufasc;
                  for(i=0;i<8;i++)
                  {
                       if(data&(128>>i))
                       {printf("%c",'#');m++;}
             else
                       {printf("%c",'-');m++;}
         
                  }
                  if(m>7)
          printf("\n");
          }
}

int main()
{   
   Lcd_DispAsc("A");
   return 1;
}

字模点阵是多少？怎么排列的？

gushiyi 发表于 2010-12-17 09:35:26

16*8点阵，是把下列数组写到了asc的二进制文件中，在文件中寻找的，感觉总是找不对偏移地址，不是说每个ASC占16个字节，又没有机内码，那应该是直接乘16就可以了吧？？？！
