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

利用动态扫描和定时器1在数码管上显示 出从765432开始以1/10秒的速度往下递减 直至765398并保持显示此数，与此同时利 用定时器0以500MS速度进行流水灯从上至 下移动，当数码管上数减到停止时，实验 板上流水灯也停止然后全部开始闪烁，3秒 后（用T0定时）流水灯全部关闭、数码管上 显示出"HELLO"。到此保持住。 设晶振频率为12MHz。-The use of dynamic scanning and Timer 1 in the digital control to show from the beginning of 765,432 to 1/10 seconds until the speed of descending down 765,398 and maintain display this number, at the same time the use of Timer 0 to 500ms the speed of light from the flowing water to Under the move, when reduced to a few digital tube stop, the experiment on-board water stop and then all the lights started to flicker, 3 seconds later (T0 regularly used) closed water lights, digital tubes show
