实验一单片机仿真开发系统的使用

1.1KeilC51集成开发环境介绍

①、运行keilC51编辑软件，软件界面如图1-1所示
②、建立一个新的工程项目
单击Project菜单，在弹出的下拉菜单中选中NewProject选项

③、保存工程项目
a、选择要保存的文件路径，输入工程项目文件的名称，如保存的路径为C51文件夹，
工程项目的名称为C51，如图所示，单击保存

b、为工程项目选择单片机型号
在弹出的对话框中选择需要的单片机型号，如图所示,这里选择51核单片机中使用较多的
89S51，选定型号后，单击确定，出现如图所示的开发平台界面

④、新建源程序文件
在下图中单击“File”菜单，选择下拉菜单中的New选项，新建文件后得到如图的界面：

程序录入区域

⑤、保存源程序文件
单击“File”菜单，选择下拉菜单中的Save选项,在弹出的对话框中选择保存的路径及
源程序的名称，如图所示。此时光标在编辑窗口里闪烁，这时可以键入用户的应用程序了，
建议首先保存该空白的文件，单击菜单上的“File”，在下拉菜单中选中“SaveAs”选项单
击，屏幕如下图所示，在“文件名”栏右侧的编辑框中，键入欲使用的文件名，同时必须键
入正确的.扩展名。注意，如果用Ｃ语言编写程序，则扩展名为(.c)；如果用汇编语言编写程
序，则扩展名必须为(.asm)。然后，单击“保存”按钮

注意扩展名

⑥、为工程项目添加源程序文件
在编辑界面中，单击“Target”前面的“+”，再在“SourceGroup”上单击右键，得到如图
所示的对话框，选择“AddFiletoGroup’SourceGroup1’”，弹出如图所示的对话框，选
中要添加的源程序文件，单击“Add”，得到如图所示的界面，同时，在“SourceGroup1”
文件夹中多了一个添加的“Text1.c”文件。

⑦、输入源程序源程序输入完成后保存，得到如图所示的界面。程序中的关键字以不同的
颜色提示用户加以注意，这就是事先保存待编辑的文件的好处，即Keilc51会自动识别关键
字

⑧、编译调试源程序
在上图中，单击Pro
