Step 2. Download SDK - 下载 ESP8266 软件源代码

[ESP_Faye]

Download ESP8266 SDK.

ESP8266_NONOS_SDK is the SDK without OS.
1. IOT_Demo in folder "examples" is a demo in which we exampled ESP8266 how to run as device "Plug", "Light", or "Sensor", these three devices are defined in user_config.h, please only enable one of them every time.
2. AT is another demo, if we want to use ESP8266 as a slave which can be controled by a host with AT commands.
3. Both IOT_DEMO and AT need to compile based on ESP8266_NONOS_SDK, copy one of them as folder "app" which in ESP8266_NONOS_SDK and then compile.

ESP8266_RTOS_SDK is the SDK with FreeRTOS, it is open source on github.
1. ESP8266_RTOS_SDK wiki.
2. ESP8266_IOT_PLATFORM is the demo application based on ESP8266_RTOS_SDK.

Hope this is helpful, thanks for your interest in ESP8266 !

开发者可以在 BBS 的 Downloads 板块中下载最新 release 的软件

ESP8266_NONOS_SDK 是不带操作系统的 SDK，IOT_Demo 和 AT 的编译都基于它。
1. IOT_Demo 位于 ESP8266_NONOS_SDK/examples 路径中，给出三种物联网设备“智能开关”，“灯”，“传感器”的简单应用示例，三种设备在user_config.h 中定义，请每次只使能一种设备调试。
3. AT 是另一个应用示例，示范 ESP8266 作为 slave 外接一个 Host，Host 通过 AT 指令控制 ESP8266 联网传数据等操作。
4. AT 是与 IOT_Demo 同一级别的应用示例，请勿同时拷贝到文件夹“app” 编译。未改动代码的情况下，要么运行 IOT_Demo，要么运行 AT。

ESP8266_RTOS_SDK 是基于 FreeRTOS 的 SDK，在 github 上开源。
1. 简单说明可参考 wiki 。
2. ESP8266_IOT_PLATFORM 是基于 ESP8266_RTOS_SDK 的应用示例。
