<hr>
<p style="line-height:1.8"><strong>1.实现原理</strong></p>
<p style="line-height:1.8">主控为立创·开源SF32LB52模组，通过该主控以及麦克风和喇叭，实现与小智联网对话，并通过按键实现唤醒功能，从而降低功耗。</p>
<p style="line-height:1.8"><strong>2.模块详解</strong></p>
<p style="line-height:1.8">主控部分：立创·开源SF32LB52模组，一款蓝牙低功耗芯片，频率 <strong>240MHz。</strong></p>
<p style="line-height:1.8">电源部分：一节CR123A电池，<strong>电压3.7V</strong>，尺寸34(L) x 16.5(W) mm，自带Type-C充电口。一个拨动开关，可实现通电和断电。</p>
<p style="line-height:1.8"><img src="https://image.lceda.cn/oshwhub/pullImage/1818e55141b84e9a855412b2b5502dc6.png"></p>
<p style="line-height:1.8">音频功放与喇叭部分：采用LM4871芯片，是一款音频功率放大器芯片，工作电压 1.9 - 5.5V。喇叭选用3020_8欧2瓦_带线2P_1.25腔体喇叭。R2和R3两个电阻可控制喇叭的音量，阻值越大，音量越小。</p>
<p style="line-height:1.8"><img src="https://image.lceda.cn/oshwhub/pullImage/0b05681fd06f4339a04597864f08d369.png"></p>
<p style="line-height:1.8">麦克风部分：由一个麦克风咪头、一个电容以及一个电阻组成。</p>
<p style="line-height:1.8"><img src="https://image.lceda.cn/oshwhub/pullImage/5f99613b5c52405b8e47fdcaa4805ca4.png"></p>
<p style="line-height:1.8">屏幕部分：采用一块1.69寸LCD屏</p>
<p style="line-height:1.8"><img src="https://image.lceda.cn/oshwhub/pullImage/549ed337f63f46e499a22148261fbf3a.png"></p>
<p style="line-height:1.8">按键部分：由两个按键及一些电阻组成，U6按键用来唤醒小智。U5按键功能待定。</p>
<p style="line-height:1.8"><img src="https://image.lceda.cn/oshwhub/pullImage/512aba331f854a4d8da832c71bbefeae.png"></p>
<p style="line-height:1.8">LED部分：用来实现LED指示功能，由主控的PA32控制，输出低电平灯亮。</p>
<p style="line-height:1.8"><img src="https://image.lceda.cn/oshwhub/pullImage/80ad2a7338d84becaefc1ea6bcf5d777.png"></p>
<p style="line-height:1.8">串口下载部分：通过串口烧录程序，也可使用串口与主控进行通信，主控PA18为RXD，PA19为TXD</p>

<p style="line-height:1.8"><strong>烧录教程：</strong></p>
<p style="line-height:1.8">1.下载附件中的压缩包，解压后得到以下文件</p>
<p style="line-height:1.8"><img src="https://image.lceda.cn/oshwhub/pullImage/929c1a553dd540edafc97b044a3ea959.png"></p>
<p style="line-height:1.8">2.用一个USB转串口模块，连接板子与电脑。然后打开1.3命令.txt文件，将COM17改为你自己的串口号（可在控制面板—设备管理器中查看），然后全选并复制。</p>
<p style="line-height:1.8"><img src="https://image.lceda.cn/oshwhub/pullImage/d4c364228f16499e85eba1cade3a39cd.png"></p>
<p style="line-height:1.8">3.右键sftool.exe文件，选择在终端中打开</p>
<p style="line-height:1.8"><img src="https://image.lceda.cn/oshwhub/pullImage/e19300206e5f46488bfdfe824be41b5d.png"></p>
<p style="line-height:1.8">4.在弹出的界面中粘贴刚刚复制的内容，按回车等待烧录完成即可</p>
<p style="line-height:1.8"><img src="https://image.lceda.cn/oshwhub/pullImage/2345f83347cf45e0a27cb46b1fba62fe.png"></p>
<p style="line-height:1.8">5.烧录完成后会重启，之后来到这个界面</p>
<p style="line-height:1.8"><img src="https://image.lceda.cn/oshwhub/pullImage/a52a1c675b8945aba6897bcaf5ca30c4.png"></p>
<p style="line-height:1.8">6，打开蓝牙，并且开启蓝牙共享网络功能。连接成功后，最后会来到这个界面。</p>
<p style="line-height:1.8"><img src="https://image.lceda.cn/oshwhub/pullImage/5d1097d6f22a4ba3aeefcf45a504a531.png"></p>
<p style="line-height:1.8">7.这时，打开<a href="https://xiaozhi.me" target="_blank">https://xiaozhi.me</a>，点击控制台，用手机号登录。新建智能体，然后添加设备码。这样就烧录完毕，可以与小智进行对话了；</p>
