Welcome to Sming Framework

Let’s do smart things!!!

Sming is an asynchronous C/C++ framework with superb performance and multiple network features. Sming is open source and is tailored towards embedded devices. It supports multiple architectures as ESP8266 for example.



  • Superb performance and memory usage (Sming compiles to native firmware!)

  • Fast and user friendly development

  • Simple yet powerful hardware API wrappers

  • Compatible with standard Libraries - use any popular hardware in few lines of code

  • Multiple file system support: Installable File System, SPIFFS IFS Library, LittleFS

  • Built-in powerful wireless modules

  • Powerful asynchronous (async) network stack.

  • Async TCP and UDP stack based on LWIP.

  • With clients supporting: HTTP, MQTT, WebSockets and SMTP.

  • And servers for: DNS, FTP, HTTP(+ WebSockets), Telnet.

  • With SSL support for all network clients and servers. Based on axTLS and BearSSL.

  • Over-The-Air(OTA) firmware upgrades via HTTP(S) and MQTT(S).

  • ESP8266 specific features

  • Linux/Windows features

  • Sming has a host emulator that allows libraries and sample applications to be compiled on a Linux/Windows host system and be tested before uploading them to an actual microcontroller.
