拷拷贝到你的Keil安装目录下的c51in文件夹中。 工程文件中需设置一下: project->Option for Target Target1 选Debug页 左侧最下面 Dialog Dll 一般是DP51.DLL，不用修改 Parameter 中是 -P51 在其后加入 -dledkey 即该行看起来应该是这样的： -p51 -dledkey 保存即可 进入调试后，点击：Peripherals，其中多出一个“键盘LED实验仿真板”选择该项即可。-emboss your copy of the Keil installation directory under the decoder bin folder. The project document to be provided as follows : project-gt; Option for Target Target1 election Debug bottom of the left page is generally Dialog Dll DP51.DLL, need not be amended Parameter is- P51 add after-dledkey that the bank should look like this :-p51-can be preserved into dledkey to debug and click : Peripherals, in which more than a "keyboard LED simulation board," which can be chosen.

具有固定的“红灯―绿灯”转换间隔，并自动切换。它们一般由“通行与禁止时间控制显示、红黄绿三色信号灯和方向指示灯”三部分组成。在交通灯的通行与禁止时间控制显示中，通常要么东西、南北两方向各50秒；要么根据交通规律，东西方向60秒，南北方向40秒，时间控制都是固定的。交通灯的时间控制显示，以固定时间值预先“固化”在单片机中，每次只是以一定周期交替变化。-having fixed the "red light-green light" switch partitions, and automatic switching. They are generally from "prohibiting access and time control, red-yellow-green lights and direction indicator" is composed of three parts. Traffic lights in the passage of time and prohibit control indicates that things are usually either the north-south direction of the two 50 seconds; either on the basis of traffic laws, an east-west direction 60 seconds, 40 seconds north-south direction, the time control are fixed. Traffic lights to the time control, a pre-fixed time value "cured" in SCM, each is a certain cycle alternation.
