【RTT大赛作品连载】AB32VG1评估板 音乐播放器
之前，记录了从新建项目到点灯，按钮控制彩灯测试！接下来看看在如何ab32vg1评估板实现音乐播放器！
硬件如图：
要用到tf卡，和美标3.2mm耳机 在rt-threadstudio的音乐播放器项目到对应开发配置！！！整体配置：
详细配置如下：
内核设置如图（注意不要多选，或者少选！！！）
组件如图：
软件包如图：
硬件设置如图：
以上就是在rt-threadstudio的设置，这是我验证过的设置！！！其他的设置是否可用存在很大问题！！！我自己试过选择mp3格式，结果异常一大堆！！！所以建议在设置项目的时候尽量要注意！！！我也希望用截图这种直观的方式，快速记录项目设置的每个细节！尽量保证照着这个记录重新建类似的项目一次成功！！！
下面就是软件实现！有了前两次的ab32vg1评估板项目调试经验！这次相对就顺利多了！
软件逻辑是初始化后先获取对应目录下的.wav格式文件列表！在自动播放第一首歌！效果如图！
接下来就是通过按键实现各种操作！如图：
增加了两个关联变量，控制声音，及播放完毕

即可实现ab32vg1评估板 音乐播放器！
目前只支持.wav格式，其实一个好的播放器应该支持多种音频文件格式!如：mp3,aiff!有兴趣的爱好者可以在此基础上实现更多或者自己更喜欢的方式！！！
