[ESP32-Audio-Kit音频开发板测评]二、下载音频固件
<p>这周我在官网下了下载FLASH的软件。</p><p>也下了音频开发板的固件。<a href="https://docs.ai-thinker.com/esp32-audio-kit-factory-bin">https://docs.ai-thinker.com/esp32-audio-kit-factory-bin</a></p>
<p>总共三个bin文件，我把第一个最全的烧进去了。</p>
<p></p>
<p> </p>
<p>我用串口助手观察，发现没有声音，只有噪声。我想得改那个I2C引脚。那就得搭开发环境了。</p>
<p>以下是我串口的数据，按KEY2是WIFI同SD卡的切换。</p>

<p>这是几天 以前的实验了，但我今天觉得奇怪，我打开固件那个连接，固件下载居然没了。给我感觉，厂家对音频我觉得不太认真。因为固件根本就是以前版本的。</p>
<p> </p>
<p>技术支持很少啊。没有资料怎么玩？？</p>
<p>但是这不就是一个专门为音频设计的开发套件吗？</p>
<p>从串口数据来看，基本是可以控制音频了</p>
<p>赚个积分</p>
