本節會介紹如何實現

WizFi250+Arduino Uno

和更新的溫度數據到Xively服務器。

開始本節

之前

，你也可以閱讀Xively與WizFi250/ WizFi270的話題。

這裡包括了源文件顯示在Github上（基於網絡的Git倉庫託管服務）
github.com/Wiznet/Arduino_WizFi250/tree/master/Software/WizFi250

基本定義

連接到 AP

該是無限循環部分，負責發送數據和斷開

// The loop function is called in an endless loop
void loop()
{
	char TempC[20] = "";
	floatToString(TempC, getTempC(), 2, 7);
	String dataString = "TempC,”;
	dateString += TempC;
	if (Wifi_setup)
	{
		wizfi250.RevPacket();
		if (myClient.available())
		{
			char c = myClient.recv();
			if (c '= NULL) { 	Serial.print(c);
			}
		}
		else
		{
			if (!myClient.getIsConnected() && lastConnected)
			{
				Serial.printIn();
				Serial.println("disconnecting.");
				myClient.stop();
			}
			if (!myClient.getIsConnected() && (millis() - lastConnectionTime > postingInterval))
			{
				sendData(dataString
				};
			}
			lastConnected = myClient.getIsConnected();
		}
	}
}

發送數據與Xively Http請求格式

void sendData(String thisData)
{
	uint8_t content_len[6] = { 0 };
	String TxData;
	if (myClient.connect() == RET_OK)	// RET_OK
	{
		Serial.println("connecting..");
		// send the HTTP PUT request:
		TxData = "PUT /v2/feeds/";
		TxData += FEEDID;
		TxData += ".csv HTTP/1.1\r\n";
		TxData += "Host: api.xively.com\r\n";
		TxData += "X-Apikey: ";
		TxData += APIKEY;
		TxData += "\r\n";
		TxData += "Content-Length:”;
		itoa(thisData.length(), (char*) content_len, 10);
		TxData += (char*) content_len;
		TxData += "\r\n";
		TxData += “Content - Type: text / csv\ r\ n ";
		TxData += "Connection: close\r\n";
		TxData t = “\r\ n ";
		TxData += thisData;
		TxData t = "\r\n\r\n";

		nyClient.send((String) TxData);
		lastConnectionTime = millis();
	}
}

獲取溫度

然後，您可以驗證（按Ctrl R）和上傳（Ctrl鍵U）到

Arduino Uno  通過配置工具。

打開串口監視器（按Ctrl + Shift+ M）
