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
    1. 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。
    1. 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：



    1. GPIO 配置引脚输出
    1. 中断引脚配置
    1. NVIC中断配置
    1. 串口配置
    1. 代码预览功能查看
    1. 工程代码生成配置

  • Firmware Library固件包下载：https://www.arterytek.com/cn/product/AT32F435.jsp#Resource

  • 📜生成的工程：

    1. 使用DAP-LINK进行程序下载

  • 串口打印信息：
