<div> <h3 style="line-height:1.8;"> 1、项目功能介绍</h3> <hr> <div> <div>基于立创开源蓝牙模组制作的简易AI对话机器人，实现AI实时语音对话。它能够听懂你的情绪，解答你的疑惑，也能分享你的快乐。</div> <div>该项目分为插件版和贴片版，插件版便于焊接，贴片版建议使用热风抢或加热台焊接。</div> <div>本项目为官方训练营项目，附上原官方资料：<a href="https://lceda002.feishu.cn/wiki/B2LLwyC7binHuJkkHGMce03wnWf?fromScene=spaceOverview" target="_blank">插件版小智AI设计教程 - 飞书云文档</a></div> </div> <h3 style="line-height:1.8;">2、项目属性</h3> <hr></div> <p>本项目为训练营实战项目，电路设计和布局均参考了官方的资料。</p> <h3 style="line-height:1.8;"> 3、开源协议</h3> <hr> <p style="line-height:1.8;">GPL3.0</p> <h3 style="line-height:1.8;">4、硬件部分</h3> <hr> <p style="line-height:1.8;"><span style="font-size:12pt;"><strong>完整原理图：</strong></span></p> <p style="line-height:1.8;"><img src="https://image.lceda.cn/oshwhub/pullImage/f681ec97a9904440a7db6ae0382c5243.png" alt="f681ec97a9904440a7db6ae0382c5243.png"></p> <p style="line-height:1.8;"><strong>按键部分：</strong></p> <p style="line-height:1.8;"><img src="https://image.lceda.cn/oshwhub/pullImage/c7736271274b4c13adccaf069fa98ca7.png" alt="c7736271274b4c13adccaf069fa98ca7.png"></p> <p style="line-height:1.8;">U3按键为高电平有效，由于VSYS为电池电压，最高4.2V，主控的io端口能承受的电压为3.3v，估采用串联电阻分压，R2为10k时，R1电阻最小值为2.7K，由于不想多一种规格的电阻，估R1选用了10k。</p> <p style="line-height:1.8;"><strong>功放与喇叭部分：</strong></p> <p style="line-height:1.8;"><img src="https://image.lceda.cn/oshwhub/pullImage/7e54b41cefe443febc6ac627c2e92f2c.png" alt="7e54b41cefe443febc6ac627c2e92f2c.png"></p> <p style="line-height:1.8;">功放芯片最高支持3W，由于电池供电为最高4.2v，理论最高功率为2w，实测2w的小喇叭能带动，电量低的时候声音会出现失真，如需大功率喇叭需更换功放芯片。</p> <p style="line-height:1.8;"> </p> <h3 style="line-height:1.8;">5、软件部分</h3> <p><strong>前置准备</strong></p> <div> <div>在开始之前，我们需要进行一些前置工具，请确保完成以下的步骤：</div> <ol> <li> <div>sftool: 用于SF32系列SoC芯片的烧录</div> </li> <li> <div>下载固件： 开发板的固件位于 <a href="https://github.com/78/xiaozhi-sf32/releases" target="_blank">https://github.com/78/xiaozhi-sf32/releases</a>，我们下载最新release版本的压缩包。需要注意的是，我们一共需要<code>bootloader.bin</code>、<code>ER_IROM2.bin</code>、<code>ER_IROM3.bin</code>、<code>ER_IROM1.bin</code> 和<code>ftab.bin</code>这五个文件。 建议先下载sftool工具，下载完成后将这些文件放在sftool文件夹中，与sftool.exe同一路径。</div> </li> <li> <div>开发板对应固件：小汤圆直插版（立创训练营）: sf32lb52-xty-ai-tht.zip</div> </li> </ol> </div> <p>固件烧录需要用到sftool工具：<a

target="_blank">https://downloads.sifli.com/github_assets/OpenSiFli/sftool/releases/download/0.1.3/sftool-0.1.3-x86_64-pc-windows-msvc.zip</a></p> <p>sftool1.3.0版本烧录命令：(COM3需修改为你电脑实际的下载器串口号)<br><code>.\sftool.exe -p COM3 -c SF32LB52 write_flash bootloader.bin@0x12010000 ftab.bin@0x12000000 ER_IROM2.bin@0x12A28000 ER_IROM3.bin@0x12268000
