周立功LPC214X关于硬件出发转换的程序.-Ligong LPC214X weeks starting on the hardware conversion process.

14*14点阵，调整为14×16 的。 不同于16*16，12*12的，比12*12的大气， 又不象16*16的满格，字与字之间没有什么间隙。 纵向取模，字节倒序。 先取上面的14字节， 在取下面的14字节。 是14×14的字库加入了拼音的索引。并且索引的汉字部分做了简单的划分，避免一个拼音对应的汉字分在2个区中 原拼音索引格式是 0-0xd4f 拼音索引 8个字节一个记录，前面6个字节是拼音，后面2个字节是汉字所在的地址。（高字节在后，低字节在前） 映射在本字库的7B00-884F区 0x1000―0x2167 汉字区 映射在8880－99e7 0x2168―0x468f 汉字区 映射在3da50－3ffff 在【显示程序】里面有关于上面14×16字库中的读取程序，-14* 14 dot matrix, adjusting for the 14 16. Unlike 16.12* 16* 12, 12* 12 in the atmosphere, not like 16* 16 full grid of characters and characters no gap. Vertical take-mo, reverse-byte. Take the first 14 bytes above, the admission of the following 14 bytes. 14 14 is the character of the alphabet to join the index. Index of Chinese characters and do some simple division and avoid a corresponding Chinese phonetic pm in two areas Zhongyuan phonetic index format is 0-0xd4f phonetic indexing an 8-byte records, previous six byte is phonetic, behind two Chinese characters which is the byte address. (High byte in the post, little endian) mapping in the font 7B
