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.
