PSD813F2的FLASH区操作的一个很有用的程序--A useful program of operating FLASH in PSD813F2.

通常的汉字显示方式是先根据所需要的汉字提取汉字点阵（如16×16点阵），将点阵文件存入ROM，形成新的汉字编码；而在使用时刚需要先根据新的汉字编码组成语句，再由MCU根据新编码提取相应的点阵进行汉字显示。在这种显示方式中，如果使用的流字数量较大或语句较多时，利用汉字的新编码组成语句将是一件十分繁琐而枯燥的工作。针对这种情况，本文提出了一种十分简单的方式――直接利用PC机的汉字内码作为单片机系统的编码。-Chinese characters are usually displayed in accordance with the need to first extract of the Chinese character dot-matrix (such as 16 × 16 dot matrix), will be deposited into the matrix documents ROM, a new Chinese character encoding while just need to use the Chinese characters according to the new code composed of statements, and then by the MCU according to the new code to extract the corresponding Chinese character dot-matrix display. In this show the way, if you use the word flow statement number of the larger or more, the use of Chinese characters composed of a new coding language will be a very tedious and boring work. In view of this situation, this paper presents a very simple way- direct access to PC-code character encoding as a single-chip microcomputer system.
