【XR806开发板试用】 PWM播放《铃儿响叮当》发布在 Wireless & Analog Series
PWM播放<<铃儿响叮当>>
参考
OpenHarmony LYEVK-3861开发板播放《蜜雪冰城》
OpenHarmony Neptune开发板PWM驱动 播放《小星星》
收到XR806开发板了，之前在公众号看到有人用开发板播放蜜雪冰城，快到圣诞节了，今天试下播放<<铃儿响叮当>>。环境搭建
- WSL2 Ubuntu 20.04 LTS开发环境搭建
感觉和正常的Ubuntu环境配置(220119发现链接失效，我从提交记录里找到了当时参考的那一篇)没啥区别，区别有以下几个
a.在 安装必要的库和工具的时候把
libc6-dev-amd64替换为libc6-dev就成，这个方法参考github上边wsl给的遇到E: Unable to locate package libc6-dev-amd64的解决方案b.我没装LLVM也可以烧录
- XR806开发板、无源蜂鸣器
开发
曲谱

XR806系统选择问题咨询（2023年8月）发布在 Wireless & Analog Series
很长时间没有用这块板子了，最近又需要用起来。想咨询下大家这么几个问题：
- FreeRTOS需要在全志客户服务平台下载，我属于学生开发者没发完成资质认证怎么办？
- 21年左右接触过XR806的鸿蒙开发，今天在查看开发者论坛的时候看到了XR806 SDK的相关内容，这个SDK和鸿蒙和FreeRTOS的关系是什么呢？
