【window下配置Maxim SDK环境】

1. 前言

MAX78000FTHR为快速开发平台，帮助工程师利用MAX78000 Arm® Cortex® M4F处理器快速实施超低功耗、人工智能(AI)方案，器件集成卷积神经网络加速器。本文为MAX78000羽毛板搭建window开发环境。

• 下图为板载资源
  
  具体硬件介绍见

2. Maxim SDK下载

温馨提示：接下来需要安全上网，否则一定会失败哟！

官网地址：https://www.maximintegrated.com/en/design/software-description.html/swpart=SFW0010820A

3. Maxim SDK安装

3.1 安装详解

• 下载完成后，双击安装
  
• 看到上面的提示点击下一步
  
• 此过程需要远程连接maxin官网，一定要安全上网
  
• 修改安装位置，下一步
  
• 勾选VS code支持，只选择MAX7800，下一步
  
• 接受许可，下一步
  
• 默认下一步
  
• 需要4.43GB，点击安装
  
  静静需要20分钟左右，可以去喝杯咖啡，也不介意你打赏一下小弟，请我喝杯咖啡，下面有交流群，可以相互问问题哟！
  

3.2 安装完成

在搜索栏中找到这全家桶，

• Eclipse就是调试编译下载全覆盖的UI编程软件；
• Maxim就是辅助下载的软件；
• MinGW就是命令行方式的编译下载的软件；

4. 测试环境

4.1 新建Hello word demo

• 点击Eclipse，这个是检查更新，不急
  
• 新建一个demo，file>new>Project
  
• 选择Maxim Microcontrollers，下一步
  
• 配置默认工作位置，首先helloworld吧，下一步
  
• 按照我的配置就好，finish
  
• 打开Helloword demo如下
  main.c

}

• 大家插入系统demo可以看看readme.md,分别实验验证
  

4.2 编译调试下载

• 将Maxim通过安卓数据线连接到电脑上
  
• 连接正常会出现DAPLINK 的U盘，如下查看
  

如果故障了，可参照官网刷固件还原！

4.2.1 clean

• 鼠标右键项目，点击clean project，清除原有编译结果（clean)
  

• 显示清除成功
  

4.2.2 build

• 鼠标右键项目，点击build project，编译项目（build)
  
• 呼吸灯，打印Hello World!程序，生成elf为编译成功
  

4.2.3 Openocd

现在下载程序，采用Openocd

• 鼠标右键项目，点击Debug as，选择Debug configurations（Debug)
  
• 选择GDB Openocd Debugging下的Helloworld，点击Debug就开始下载程序啦！
  
  打印如下，就下载成功啦！

5. 实验效果

• 此时板载绿灯一直闪烁，
  
• 复位或者F8开始运行程序
  
  
• 打开串口调试助手，我用的Serial studio，设置好115200波特率，选择端口连接，调试如下
  

6.小结

通过对这篇文章我们掌握了window下配置Maxim SDK环境，接下来会有许多有趣的实验，尝试与Arduino通讯做语音小车，进而丰富我们的生活。从而实现对外部世界进行感知，充分认识这个有机与无机的环境，科学地合理地进行创作和发挥效益，然后为人类社会发展贡献一点微薄之力。
再次非常感谢大赛支持和胡同学
