Sming - Open Source framework for high efficiency WiFi SoC ESP8266 native development with C++ language.
- Fast & user friendly development
- Work with GPIO in Arduino style
- High effective in perfomance and memory usage (this is native firmware!)
- Compatible with standard Arduino libraries - use any popular hardware in few lines of code
- Build-in file system: spiffs
- Build-in powerfull network and wireless modules
- Build-in great JSON library: ArduinoJson
- Open source LWIP implementation
- Simple and powerfull hardware API wrappers
- Based on Espressif SDK v1.0
- Download ESP8266 Unofficial DevKit
- Import Sming example projects to Eclipse IDE
- If you have SDK v0.9.5, please rename "C:\Espressif\ESP8266_SDK\include\lwip" to lwip_old
- Compile it and flash to chip!
You can find more information about compilation and flashing process by reading esp8266.com forum discussion thread.
