keil c51在编译的时候会将0xfd的字符(有些汉字含该字符的内码)过滤, 而导致程序出错.特别是在做液晶汉字显示时. 针对这个bug.由网友编写了这个补丁. 请下载之后放到你的keilc51in 目录里,运行这个程序.就可以了. 支持v8.02-keil c51 will be at compile time 0xfd characters (some characters with the character code) filter, which led to error. particularly in the so LCD display Chinese characters. To address this bug. prepared by the users of the patch. Please after download put your keil c51 bin directory, run the process. it. support v8.02
