我是新來的這個論壇和處理整個事情。 我有一個具體的問題要問,並且非常感謝您的時間和想法!連接Arduino以太網盾並讀取數據問題PROCESSING
如何將我的Arduino與Ethernet Shield連接起來,從傳感器獲取溫度值,以便將它們看作是處理腳本? 在一個直接的Arduino腳本中,人們可以獲得該值,從以太網屏蔽層連接到服務器並執行所喜歡的任務。我已經完成了。
在我的情況下,我希望Arduino只運行從傳感器讀取模擬輸入值的腳本。 這可能嗎?
我已經使串行連接工作,並通過USB讀取值,但以太網屏蔽?我怎樣才能得到的價值,arduino讀取沒有USB /串行連接?
ps。我使用WAMP服務器等,Windows 7的
我想兩者的Arduino和處理來自http://arduino.cc/en/Tutorial/UDPSendReceiveString UDP連接的腳本示例,但
1)我不知道這是什麼,我需要,
2)我已經排除防火牆端口6000,8888我的測試,並在Arduino的腳本已經把我的Arduino的IP地址和「本地主機」,在處理腳本
的代碼複製用於更好地利用這裏

這不是直接回答你的問題,但是你能否請你先與USB /串口連接進行原型設計,以確保你可以首先發送和接收/組織信息?有一個內置的Arduino庫,應該可以幫助你... – 2013-04-26 15:19:28
謝謝你的回覆jesses, ,但正如我已經指出的,串行連接就好,一切都按預期工作。 ps。你能否指定你的原型是什麼意思? – ODstuck 2013-04-27 02:34:27
