67 /* 文本方式下的汉字显示方法
68 在文本方式下显示汉字, 需要在SED1335 等显示RAM 内建立一个自定义字符库
69 CGRAM,然后通过在相应的单元写入相应的字符代码来实现汉字的显示.
70 SED1335 等的字符代码对应的是8x8 点阵的字符块, 而一个汉字需要四个8x8
71 点阵的字符块组合显示, 所以在建立汉字的CGRAM 时, 需要四个字符代码管理一个
72 汉字, 一般是按左上部, 左下部, 右上部和右下部四部分分配代码. 比如在演示程
73 序中建立 "清华" 两个汉字的CGRAM,那么这两个汉字的代码为80H(81H,82H,83H)和
74 84H(85H,86H,87H). */
