<h3>一、项目功能介绍</h3> <hr> <p style="line-height:1.8;">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。</p> <p> </p> <h3>二、硬件部分</h3> <hr> <p style="line-height:1.8;">硬件全开源、基本全插件，该项目在硬件上，除主控外，元器件全插件，方便焊接入门与练习。</p> <div> <h4>硬件电路分析</h4> <p><img src="//image.lceda.cn/pullimage/xpE4MNigg2lx7kSP6mNLLWkAeptXNIHnVmDGZ30E.png" alt=""></p> <p><strong>1、主控</strong></p> <p><img

<strong>240MHz</strong>，集成 8MB PSRAM 和 16MB Flash，支持锂电池直接供电。BLE 连接功耗（1S间隔）仅需 7μA，BT连接功耗（1S间隔）仅需 10μA，BLE + BT 双连接功耗比同行单BT连接功耗还能降低 60%。</p> <div> <div>模组支持 BT PAN 功能可以直接连接手机上网，相比 WIFI 功耗更低，更加适合电池场景，带屏连接功耗仅 <strong>30mA</strong>。在本项目中，直接让电池电源直连模组的电源输入引脚 VSYS。这里需要注意<span style="color:#d83931;"><code>该模组电压范围要求 3.7V~4.7V</code></span>。3.3V 和 5V 供电都不行。</div> </div> </div> <div> <div>模组的 VDD33_VOUT2 是由软件控制输出的，需要芯片正常启动后才有输出3V3。</div> <div> </div> <div><strong>2、电源部分</strong></div> <div><img src="//image.lceda.cn/pullimage/nFu7u0zhmFFVgg7EIlSOE5rKltLooSaYOSkzZKM4.png" alt="" width="316"

src="//image.lceda.cn/pullimage/TKx7g4x3enHfgnWsxH9c4cB6uuw0C0NMI7yIEXru.png" alt="" width="433" height="132"></div> <div> <div> <div>音频功放主要以上图的 U6 为主，它型号是 LM4871，是一款 3W、单声道 AB 类音频功率放大器，工作电压 1.9 - 5.5V。</div> <div> <p> </p> <div> <div>器件的 1 脚 Shutdown 是芯片掉电控制引脚，为高电平时功放停止工作实现低功耗；为低电平时功放正常工作。在原理图中通过 R5 电阻让该引脚默认为高电平即芯片默认停止工作，当需要功放工作时，需要主控的 PA26 引脚输出低电平才能工作，这样只有需要用的时候才开，不用的时候默认关闭。</div> <div> <div> <div style="background-color:#f0fbef;border-color:#b7edb1;"> <div><strong>声音大小控制</strong></div> <div>通过实际测试发现，项目原理图中的 R7 和 R8 电阻跟声音大小成线性关系，两个电阻越大，声音越小；两个电阻越小，声音越大。但是声音的大小始终不会超过喇叭的实际可输出声音大小。毕竟该芯片只有 1W 的功放输出。 W 数越大，功率越高，耗电越大，声音越响。</div> <div> </div> </div> </div> </div> <div> <div> <div style="background-color:#f0fbef;border-color:#b7edb1;"> <div><strong>噪声控制</strong></div> <div>通过实际测试发现，项目原理图中的 C4 和 C5 电容跟噪声消除有关，具体如何调整数值达到理想效果参考该芯片的数据手册说明。这里简洁为一句话：高频噪声放小电容滤除，低频噪声放大电容滤除。</div> </div> </div> </div> </div> </div> </div> </div> </div> </div> </div> </div> </div> <p style="line-height:1.8;"> </p> <p

height="196"></p> <p style="line-height:1.8;"> </p> <div> <div>麦克风咪头（通常为驻极体话筒）的核心是一个可振动的极板（振膜）与固定背极板组成的电容。</div> <div> <div><span style="color:#000000;">在原理图中，R1 电阻的作用就是给麦克风的正极输入一个基准电压MIC_BIAS，这个电压是由模组控制输出的，由模组控制则可以在要用时才输出，不用时关闭，实现低功耗。R3 的电阻值为 10K，测试效果能够接受，过低则采集的音频信号弱，过高则易引入噪声。</span></div> <div><span style="color:#000000;">U2 电容的作用就是对采集的信号进行滤波，滤除高频噪声，大多是滤除滋滋滋的声音或者声音沙哑问题。</span></div> <div> </div> <div> </div> <div><strong><span style="color:#95a5a6;font-size:14px;"><span style="color:#95a5a6;font-size:14px;"><span

<h3>六、固件下载烧录部分</h3> <hr> <p style="line-height:1.8;"> </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> <div style="text-align:left;">sftool: 用于SF32系列SoC芯片的烧录</div> <div style="text-align:left;">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> <div> <div style="text-align:left;">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> <div style="text-align:left;"> <div> <div style="white-space:pre;">使用<a href="https://docs.sifli.com/projects/xiaozhi/sftool.html" target="_blank">sftool工具</a>烧录固件，打开终端之后输入如下命令（Windows）： 需要注意的是：命令中的 ./sftool.exe 中的斜杠，在不同操作系统中有不同的表现： windows是反斜杠，linux是斜杠。</div> </div> </div> <div style="text-align:left;"> <div> <pre><code>./sftool.exe -p COM3 -c SF32LB52 write_flash bootloader.bin@0x12010000 ftab.bin@0x12000000 ER_IROM2.bin@0x12A28000 ER_IROM3.bin@0x12228000 ER_IROM1.bin@0x12020000</code></pre> </div> </div> <div> <div> <div> <div style="background-color:#fff5eb;border-color:#fed4a4;"> <div style="white-space:pre;"><code>bootloader.bin</code>、<code>ER_IROM2.bin</code>、<code>ER_IROM3.bin</code>、<code>ER_IROM1.bin</code> 和<code>ftab.bin</code>是你下载的固件文件名，建议使用绝对路径引用，如果路径中出现中文或者空格请用<code>"</code>将路径括起来。 其中<code>COM3</code>是你连接开发板的串口号，可能会有所不同，请根据实际情况修改。 可以打开设备管理器查看对应串口号：'COM'后面接着的数字就是串口号</div> </div> </div> </div> <div>没有意外的话，烧录完成之后会自动重启运行，屏幕应该被点亮。</div> <div> </div> <div> </div> <div> </div> <div> <h3>七、使用说明</h3> <hr> <p style="line-height:1.8;"> </p> <div> <div>在连接板子设备之前，打开手机的蓝牙网络共享功能，烧录固件之后，确保蓝牙共享网络已打开，这时，手机就可以连接蓝牙 sifli-pan 设备了，这个时候，打开浏览器，输入网址：<a href="https://xiaozhi.me/" target="_blank">https://xiaozhi.me</a>。浏览器用手机或者电脑都可以。 进入小智 AI 的网页后，点击控制台，用手机号登录。</div> <div> <div>新建智能体填写，最后添加设备码。</div> <div>这个时候拔掉开发板上的数据线再接入就可以正常使用了</div> <div><img src="//image.lceda.cn/pullimage/2tY3EMaoOUnnqpEtMjwvnc1dXIbJLxk89szed9vC.png" alt=""
