摘　　要：基于嵌入式系统μC/OS-II的个人数字助理中的汉字处理技术主要包括汉字的输入和汉字存储的处理。汉字的输入采用拼音输入法,汉字内码以Uni code编码的形式存放,采用阶梯法查找的方式查找与拼音输入码一致的汉字,从一组相同发音的汉字中选择需要的汉字。Unicode编码中一个汉字使用一个16位数表示,英文字符使用一个8位数表示,μC/OS-II操作系统的文件系统只能直接读写英文字符,在读写和显示汉字时,需要进行中间转换处理。Chinese processing technology of PDA (Personal Digital Assistance)based on the embedded operating system μC/OS-II includes the input method and the processing of its storage.The internal code of Chinese is Unicode and the input method is PINYIN.A ladder's method is used to find the Chinese character corresponding to the input code,then the proper character will be chosen from a group of characters with the same pronunciation. In computer,a Chinese character is represented by a 16-bit digit and a English letter is represented by an 8-bit digit.The file system of the μC/OS-II can not read and write Chinese character directly.It is necessary to make some conversion between reading or writing and display of Chinese.
