要在屏幕上显示文字，其实就是在二维点阵上，用一个个点来组成文字。描绘的点的形状不同可以形成不同的字体。

上图中，显示一个“A”用的是16x16的点阵，被画到的点用1表示，未被画到的点用0表示。第一行没有画到点，所以是“00000000，00000000”（二进制）=“0x00,0x00,（十六进制）”，第二行和第三行同理。第四行是“00000001，11000000”==“0x01,0xC0”。以此类推可以得到如下“A”的字模编码。

//A
0x00,0x00,0x00,0x00,0x00,0x00,0x01,0xC0,0x03,0xC0,0x02,0xE0,0x06,0x60,0x04,0x70,
0x0C,0x30,0x0F,0xF8,0x18,0x38,0x10,0x1C,0x30,0x1C,0xFC,0x3F,0x00,0x00,0x00,0x00,

我们按照ASCII码表里的排列顺序，依次提取它们的字模编码。这样做的好处是，我们可以用该字符的ASCII码值算出它在字库里的偏移位置。
offset = (ASCII码 - 32) x 32;
-32表示字库的第一个字符' '的ASCII码为32,
x32表示每个字符在字库数组里占用32个字节

如果要显示汉字，因为汉字比较多，制作比较耗时间，可以调用现成网上制作好的HZK16字库，HZK16字库是符合GB2312标准的16×16点阵字库。GB2312标准里将汉字和图形符号排列在一个94行94列的二维代码表中，每个汉字用两个字节编码，第一个字节叫区码，第二个字节叫位码，范围为A1A1~FEFE。
汉字在HZK16中的偏移地址,
offset = (94x(区码-0xA1)+(位码-0xA1))x32。
x32表示每个字符占32个字节
