其中有一段是显蔽昌示变量的，那个时候简单写的，你试试看

利用PC上的16×16点阵扰扒汉字库，提取后将点阵文件存入ROM，直接利用PC中汉字内码作为单片机系统的编码（不再形成新的汉字编码）。

在数字电路中，所有的数据都是以0和1保存的，对LCD控制器进行不同的数据 *** 作，可以得到不同的结果。对于显示英文 *** 作，由于英文字母种类很缓穗昌少，只需要8位（一字节）即可。而对于中文，常用却有6000以上，将ASCII表的高128个很少用到的数值以两个为一组来表示汉字，即汉字的内码。而剩下的低128位则留给英文字符使用，即英文的内码。

那么，得到了汉字的内码后，还仅是一组数字，那又如何在屏幕上去显示呢？这就涉及到文字的字模，字模虽然也是一组数字，但它的意义却与数族亏字的意义有了根本的变化，它是用数字的各位信息来记载英文或汉字的形状，如英文的“A”在字模的记载方式如图
