摘　　要：针对嵌入式应用系统下的汉字输入和显示的问题,利用汉字编码技术、触摸屏控制技术和LCD显示技术,基于ARM9嵌入式硬件开发平台,在VxWorks操作系统中利用设计的拼音码与汉字机内码转换引擎实现拼音到汉字的映射,获取相应汉字,然后通过汉字字形点阵在LCD上显示汉字。该设计原理清晰,易于实现,具有一定的工程应用价值。For Chinese character input and display in embedded system, making use of design for transition engine for Chinese character inner code and spelling code to achieve mapping from spell to Chinese characters in embedded VxWorks system, the text acquires corresponding Chinese characters and displays Chinese characters on LCD through Chinese font lattice. The scheme has been implement- ed by using the Chinese character coding technology touch screen technology and LCD display technol- ogy based on ARM9 embedded hardware flat. This design has clear principle and be easy to realization that it has a certain extent for applying value on engineering.
