MDK简单编译STM程序

ARM开发环境MDK5.0建立和STM32程序的简单编译

安装Keil uVision5

1. 下载MDK5.0软件双击安装包，点“Next”

2. 勾选同意再次点击“Next”

3. 选择软件和支持包的安装路径

4. 安装过程等待几分钟

5. 安装进度完成后，选择“安装”

6. 安装完成后，点击“Finish”

STM32简单程序编译

1.点击左上方Project的New μVision Project到新建的文件夹中

2.在弹出来的对话框中选择你所用的STM32的芯片

3.新建一个main.c文件，并添加到工程中

在建立的文本文件中输入C中的main函数

点击保存

保存后，将文件添加到工程中

4.点击编译

5.编写main.c的代码
