安装mdk5软件、安装stm32包，熟悉mdk开发环境、完成一个stm32的简单程序的编译

mdk安装

1.通过指导老师提供的安装途径安装 2.完成注册（自助注册机） 3.具体步骤 找到注册机注册机crack.exe→在 keygen.exe 里面，设置 Target为 ARM→拷贝 MDK License Management 界面里面的 CID 号→复制到 keygen.exe 里面 CID栏→ 点击Generate，即可获得注册码→拷贝注册码到 License Management 里**→点击 Add LIC 即可完成注册

完成一个stm32的简单程序的编译

建立一个文件 2.打开Keil uVision5，点击Project，然后点击New uVision Project 3.芯片选择STM32F103RB 4.创建编译文件 步骤如下 双击Source Group →寻找startup_stm32f10x_md文件然后点击Add 自定义名字，选择C File文件格式

编译完成功

Proteus环境下完成一个51程序设计

暂未完成
