[STM32H7R/S]测评 ⑨nano edge ai studio 训练一个模型--下
<div class='showpostmsg'> 本帖最后由 不爱胡萝卜的仓鼠 于 2024-11-11 21:37 编辑<p>/***********************************************************************************************************/</p>
<p>本文强烈建议和上一篇文章以及datalogger的那篇一起交叉看，因为今天又学到了一点新东西。并且还发现了之前datalogger的一个重大BUG</p>
<p>/***********************************************************************************************************/</p>
<p> </p>
<p> 在上一篇中最后一步移植.a文件到工程中没能顺利完成，我个人感觉还是工程的问题，可惜我能力有限，没法解决。</p>
<p> 正经能力我可能有限，但是我歪办法多<img height="52" src="https://bbs.eeworld.com.cn/static/editor/plugins/hkemoji/sticker/facebook/pleased.gif" width="48" />。我的思路是创建一个空白工程，用Keil，然后只要boot工程，不要跳转APP工程，直接把Boot工程当做主工程来用，我看了主芯片Flash和Ram其实还是可以的，有64K Flash，620K RAM，简单跑跑这个项目应该问题不大。只要我能想尽一切办法让这个boot工程的代码能顺利编译，那就万事大吉啦</p>
<p> </p>
<div> 经过不懈努力，我终于搞定了我想要的东西，现在这个工程就是实现了之前dataLogger功能的，可以用keil编译的，相比之前的我还增加了ready信号的get，这样应该会更好一点，每次都可以保证获取到新的值。还发现之前datalogger代码的一个BUG，他打印出来的结果是错误的，偏移写的不正确。</div>
<div> 之前的工程红框位置的偏移写错了</div>
<div>
<div style="text-align: center;"></div>
<p>本次修正后</p>
<div style="text-align: center;"></div>
</div>
<div> 工程如下：（后面我把datalogger的功能整合进最终的工程了，所以这个大家有兴趣的话就打开看看，可以忽略不看，并且后续有一些代码的小修改，他和最终工程中的也不一定一致，主要是数据格式从int改成了float）</div>
<p> </p>
<div></div>
<div> </div>
<div><strong><span style="font-size:24px;">一.再次训练模型</span></strong></div>
<p> 因为上一个模型有问题，我就重新训练了一个模型，这个模型比之前的那个好，现在这个可以到100%，上一篇就92.5（不过上一篇用了错误的datalogger代码，原始样本数据就是错的，那个模型就是报废的。也没啥参考意义）。具体操作步骤我就不说了，详见上一篇</p>
<div style="text-align: center;">
<div style="text-align: center;">
<div style="text-align: center;"></div>
<p> </p>
</div>
</div>
<p> 并且在验证环节，我尝试了正确位置放正确数据，还尝试交换放数据，结果都是100%正确识别。这个模型肯定嘎嘎好用</p>
<div style="text-align: center;">
<div style="text-align: center;">
<div style="text-align: center;"></div>
<p> </p>
<div style="text-align: center;"></div>
<p> </p>
<p style="text-align: left;">/***********************************************************************************************************/</p>
<p style="text-align: left;">这里再补充一点，最后一步生成库文件时，Compilation Flags默认会勾选第1个和第3个。我的编译器可能不匹配，如果按默认的来，我这儿能编译，能运行，但是检测出来的结果一直是同一个，很奇怪，编译器这玩意也是触摸到了我的知识盲区，搞不明白。反正全部去掉勾选，就可以了</p>
<div style="text-align: center;"></div>
<p style="text-align: left;">/***********************************************************************************************************/</p>
</div>
<p style="text-align: left;"> </p>
<p style="text-align: left;"><strong><span style="font-size:24px;">二.在线验证模型</span></strong></p>
<p style="text-align: left;"> 并且本次我还发现一个很有用的东西，就是在线模拟，通过串口直接把datalogger实时采集的数据传给电脑，电脑直接运行模型，推算结果。这样就不用把模型下载到开发板上再验证结果了，并且这样在线验证后，我们就可以知道模型是不是真的好用，如果回头在开发板上运行时有问题，那至少可以排除模型的问题</p>
<div style="text-align: center;">
<div style="text-align: center;"></div>
</div>
<p style="text-align: left;"> 开发板上运行datalogger的代码，然后界面上选择串口和波特率，再点开始即可</p>
<div style="text-align: center;">
<div style="text-align: center;">
<div style="text-align: center;"></div>
<div style="text-align: center;"> </div>
<div style="text-align: center;">
<div style="text-align: center;"></div>
<p> </p>
</div>
</div>
</div>
<p style="text-align: left;"> 这个玩意儿图文不够生动，我就录了一段视频给大家</p>
<p style="text-align: left;">69151aec60f97e6d2658b72ad5fb01e5<br />
</p>
<p style="text-align: left;"><strong><span style="font-size:24px;">三.移植模型到开发版上运行</span></strong></p>
</div>
<div> 最终得到的模型压缩包如下：</div>
<div></div>
<p> 接下来就是把本次得到的新模型弄到工程中去运行一下，在如图路径创建一个文件夹，用于存放.a和.h</p>
<div style="text-align: center;"></div>
<p>然后把压缩包里的.a、.h拷贝到这个路径下</p>
<div style="text-align: center;"></div>
<p>接下来我们打开keil，然后添加nanoedgeai的文件夹和文件</p>
<div style="text-align: center;"></div>
<p> </p>
<div style="text-align: center;"></div>
<p> </p>
<div style="text-align: center;"></div>
<p> </p>
<div style="text-align: center;"></div>
<p>接下来是添加头文件路径</p>
<div style="text-align: center;"></div>
<div style="text-align: center;"></div>
<p>然后要对.a文件做一下修改，右键点击.a文件</p>
<div style="text-align: center;"></div>
<p> </p>
<div style="text-align: center;"></div>
<p> </p>
<p>接下来就是对main.c进行修改了，参照nanoEdgeAi给的示例代码，和上一篇的修改差不多，只是我这边用了printf（这玩意儿终于好用了）</p>
<p>以下是整个main.c，我这边是整合了datalogger工程和AI模型的，通过“MODE”这个宏定义控制</p>

<p><strong><span style="font-size:24px;">四.心得</span></strong></p>
<p> 本次STM32H7R/S-DK开发板的测评终于圆满完成。本次真的是收获满满，我在今年上半年就了解到ST在Ai方向的各种方案及工具，但是当时nanoedgeai还是要收费的，并且我的本职工作不是做AI方向的开发的，对于Ai相关的知识以及如何训练模型、使用模型完全不懂，是属于小白的档位，所以一直就处于观望阶段，最近nanoedgeai免费了，正好遇上H7S7开发板的试用，就趁着这个契机逼自己一把，学习一下相关的知识和技能。</p>
<p> 不得不说，ST在文档、demo、视频教程相关的技术支持、工具的设计等真的没的说，在业界绝对算的上数一数二。我通过看官方提供的学习资料，一个门外汉，通过几十小时的学习、实践。可以快速掌握模型训练、在单片上运行模型的开发技能，可以看得出来ST的工程师绝对是付出了巨大的努力，并且训练出来的模型实际效果也是非常棒，100条数据，训练一次，就得到了一个非常完美的模型，体积很小，响应很快，准确度很高。这样的结果真的是令我非常震撼，在得到结果前我一直认为会需要有多轮的训练、调参数、调整样本等</p>
<p> ·最后再次感谢ST和EEWORLD给我这次试用的机会，谢谢</p>
