Q: RTOS SDK 和 Non-OS SDK 有何区别?

Q : RTOS SDK 和 Non-OS SDK 有何区别? 主要差异点如下: 【Non-OS SDK】 Non-OS SDK 主要使用定时器和回调函数的方式实现各个功能事件的嵌套,达到特定条件下触发特定功能函数的目的。Non-OS SDK 使用 espconn 接口实现网络操作,用户需要按 照 espconn 接口的使用规则进行软件开发。 【RTOS SDK】 1. RTOS 版本 SDK 使用 freeRTOS 系统,引入 OS 多任务处理的机制,用户可以使用 freeRTOS 的标准接口实 现资源管理、循环操作、任务内延时、任 务间信息传递和同步等面向任务流程的设计方式。具体接口使用...
