基于AT32_Work_Bench配置AT32工程

---

✨AT32_Work_Bench工具是用来给AT32 MCU快速构建外设初始化工程软件，类似STM32的STM32CubeMX工具软件。

• 📍AT32 TOOL系列工具下载地址：https://www.arterytek.com/cn/support/index.jsp?index=4
• 🏷这里以AT32F435RGT7作为测试对象（对标STMF4系列），创建基于Keil平台编译的代码工程。
• 🎈对应 Keil AT pack包下载地址：https://www.arterytek.com/cn/support/index.jsp?index=4

📑工程创建

🔖下面列举一些常见外设的基本配置。

• 1. 新建工程
     
• 2. 根据个人配置习惯，先配置debug，也就是下载和在线调试方式配置。
     
• 3. CRM时钟配置：（如果选择关闭，则默认使用内部时钟源）
     
     

• 点开列表可以参看对应总线上挂载的具体的哪些外设：
  
  
  
  

• 4. GPIO 配置引脚输出
     
• 5. 中断引脚配置
     
• 6. NVIC中断配置
     
• 7. 串口配置
     
• 8. 代码预览功能查看
     
• 9. 工程代码生成配置

• 📜生成的工程：
  

• 10. 使用DAP-LINK进行程序下载
      
      

• 串口打印信息：
