[ESP32-Audio-Kit音频开发板测评] 先让板子动起来

<p><span style="font-size:12pt"><span style="background:white"><span style="font-family:宋体"><span style="font-size:10.5pt"><span style="font-family:"微软雅黑","sans-serif""><span style="color:#444444"><span style="letter-spacing:.75pt">好经过一番探索其中的一块被搞定，且下载非常方便几乎是一键完成，这款板子就是K32W061，它在命令操作窗口使用“↑”就可重现出以前使用的指令，一个回车即可加以执行。然而前期的环境构建会化一些功夫。</span></span></span></span></span></span></span></p>
<p><span style="font-size:12pt"><span style="background:white"><span style="font-family:宋体"><span style="font-size:10.5pt"><span style="font-family:"微软雅黑","sans-serif""><span style="color:#444444"><span style="letter-spacing:.75pt">再有一块就属ESP32-Audio-Kit音频开发板，开发环境的构建同样交代的不很清楚。所幸的是一位坛友介绍了用ArduinoIDE来开发的方式，还是比较实用的，起码先要让板子动起来才是硬道理！</span></span></span></span></span></span></span></p>
<p><span style="font-size:12pt"><span style="background:white"><span style="font-family:宋体"><span style="font-size:10.5pt"><span style="font-family:"微软雅黑","sans-serif""><span style="color:#444444"><span style="letter-spacing:.75pt">当然有喜也有忧，喜的是它可以让板子动起来，有的是它能否提供对语音录放的支持就是未知数了，只好先走一步是一步了。</span></span></span></span></span></span></span></p>

不错哦，回头我也试试看
<p>基本的处理用Arduino IDE还是比较容易实现的</p>
