+# 维护指南
+* 为提高可移植性、可维护性、可阅读性，开发（应用层）时尽量使用`CMSIS_OS2`的抽象接口，特殊情况时再考虑使用RTOS的原生接口
+* 线程任务实例及属性、句柄的声明及定义，独立存放在`App`文件夹 
+* 线程、定时器、事件标志、互斥锁、信号量、消息队列等功能的初始化统一在`freertos.c`文件中进行初始化（内核启动前的预装载）
+* `freertos.c`中的任务实体只保留默认任务即可
 # 勘误
  硬件的v1.0以前版本中，SYS_RESET脚和MOD_SLEEP到单片机的实际连接与网络标号是相反的（问题发生在TXB0108PWR芯片附近），故代码中在GPIO处进行了相反的设置。
