 ===== 6、编程语句块基本应用 =====
+<html><body>
+<p class=MsoNormal><span style='font-size:16.0pt'>树莓派扩展板下载在线调试固件后，就可以即时体验语句块了。（体验之前需要连接<span
+lang=EN-US>WiFi</span>，<span lang=EN-US>WiFi</span>连接部分请看树莓派<span lang=EN-US>AI</span>套件语音识别说明）</span></p>
+<p class=MsoNormal><span style='font-size:16.0pt'>例如文字转语音，找到“树莓派文本转语音”语句块，如下所示，把需要转换的汉字填入空白处，比如：你好。</span></p>
+<p class=MsoNormal align=center style='text-align:center'><span lang=EN-US><img
+width=308 height=100 src="https://www.weeemake.com.cn/wiki/lib/exe/fetch.php?media=wm_wiki:pasted:20201030-191911.png"></span></p>
+<p class=MsoNormal><span style='font-size:16.0pt'>然后鼠标点击积木块，此时，积木块周围变成黄色，过一会，喇叭会播放转换后的语音。积木块执行完成，周围的黄色消失。</span></p>
+<p class=MsoNormal><span style='font-size:16.0pt'>例如语音转文字，在软件中找到“树莓派识别语音”和“树莓派识别结果”语句块。点击“树莓派识别语音”语句块，然后对麦克风说话。</span></p>
+<p class=MsoNormal><span style='font-size:16.0pt'>结束说话一段时间，语句块下面会反馈结果，<span
+lang=EN-US>ture</span>代表识别成功，<span lang=EN-US>false</span>代表不成功。如下图中所示。识别成功后点击“树莓派识别结果”，结果就会显示在下面了。比如说“你好”。</span></p>
+<p class=MsoNormal align=center style='text-align:center'><span lang=EN-US><img
+width=181 height=101 src="https://www.weeemake.com.cn/wiki/lib/exe/fetch.php?media=wm_wiki:pasted:20201030-192002.png"><img width=79 height=44
+src="https://www.weeemake.com.cn/wiki/lib/exe/fetch.php?media=wm_wiki:pasted:20201030-192024.png"><img width=159 height=102
+src="https://www.weeemake.com.cn/wiki/lib/exe/fetch.php?media=wm_wiki:pasted:20201030-192036.png"></span></p>
+<p class=MsoNormal><span style='font-size:16.0pt'>例如物体识别，包括通用物体识别、动物识别、植物识别、文字识别。点击对应的积木块前，将摄像头对准要识别的物体，点击后，树莓派会启动摄像头拍摄一幅照片，然后传到云端。识别到物体时，该积木块会提示<span
+lang=EN-US>ture</span>。否则提示<span lang=EN-US>false</span>。</span></p>
+<p class=MsoNormal><span style='font-size:16.0pt'>结果仍然是点击“树莓派识别结果”积木块，下面就会显示识别到的几种结果。比如拍一个圆珠笔的照片，可能会反馈如下结果。</span></p>
+<p class=MsoNormal align=center style='text-align:center'><span lang=EN-US><img
+width=340 height=144 src="https://www.weeemake.com.cn/wiki/lib/exe/fetch.php?media=wm_wiki:pasted:20201030-192129.png"></span></p>

 ===== 7、供电方式和模块连接方式 =====
+<html><body>
+<p class=MsoNormal style='text-indent:21.0pt'><span style='font-size:16.0pt'>可以给扩展板提供<span
+lang=EN-US>6-12V</span>的直流电源，放电电流最好大于<span lang=EN-US>3A</span>，否则可能会造成树莓派供电不足而死机。</span></p>
+<p class=MsoNormal style='text-indent:21.0pt'><span style='font-size:16.0pt'>套件中的喇叭接入树莓派耳机接口，开机后半分钟会自动播报分配的<span
+lang=EN-US>IP</span>地址（预先输入过<span lang=EN-US>wifi</span>账号密码）。</span></p>
+<p class=MsoNormal style='text-indent:21.0pt'><span style='font-size:16.0pt'>摄像头和麦克风接入树莓派上任何一个<span
+lang=EN-US>usb</span>口，树莓派会自动识别。最好摄像头接<span lang=EN-US>usb2.0</span>上面那个接口，麦克风接<span
+lang=EN-US>usb3.0</span>下面那个接口。</span></p>
