Sming

Sming - Open Source framework for high efficiency WiFi SoC ESP8266 native development with C++ language.

Summary

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
OTA (cloud) firmware updating
Build-in file system: spiffs
Build-in powerfull network and wireless modules
Build-in great JSON library: ArduinoJson
HTTP, AJAX, WebSockets support
MQTT protocol based on [libemqtt] (https://github.com/menudoproblema/libemqtt)
Open source LWIP stack
Simple and powerfull hardware API wrappers
Based on Espressif SDK v1.0.1b1

Getting started

You can find more information about compilation and flashing process by reading esp8266.com forum discussion thread.

Examples

More information at Wiki Examples page.

Simple GPIO input/output

#define LED_PIN 2 // GPIO2
...
pinMode(LED_PIN, OUTPUT);
digitalWrite(LED_PIN, HIGH);

Connect to WiFi and start Serial communication

Serial.begin(9600);
Serial.println("Hello Sming! Let's do smart things.");

WifiStation.enable(true);
WifiStation.config("LOCAL-NETWORK", "123456789087"); // Put you SSID and Password here

Read DHT22 sensor

#include <Libraries/DHT/DHT.h> // This is just popular Arduino library!

#define WORK_PIN 0 // GPIO0
DHT dht(WORK_PIN, DHT22);

void init()
{
	dht.begin();

	float h = dht.readHumidity();
	float t = dht.readTemperature();
}

HTTP client

HttpClient thingSpeak;
...
thingSpeak.downloadString("http://api.thingspeak.com/update?key=XXXXXXX&field1=" + String(sensorValue), onDataSent);

void onDataSent(HttpClient& client, bool successful)
{
	if (successful)
		Serial.println("Successful!");
	else
		Serial.println("Failed");
}

Embedded HTTP WebServer

server.listen(80);
server.addPath("/", onIndex);
server.addPath("/hello", onHello);
server.setDefaultHandler(onFile);

Serial.println("=== WEB SERVER STARTED ===");
Serial.println(WifiStation.getIP());

...

void onIndex(HttpRequest &request, HttpResponse &response)
{
	TemplateFileStream *tmpl = new TemplateFileStream("index.html");
	auto &vars = tmpl->variables();
	vars["counter"] = String(counter);
	vars["IP"] = WifiStation.getIP().toString();
	vars["MAC"] = WifiStation.getMAC();
	response.sendTemplate(tmpl);
}

void onFile(HttpRequest &request, HttpResponse &response)
{
	String file = request.getPath();
	if (file[0] == '/')
		file = file.substring(1);
		
	response.setCache(86400, true);
	response.sendFile(file);
}
