AS3長時間發送給arduino？

我正在爲學校開展一個簡單的項目。我的麪包板上有4位數12針顯示，所有連接都正確，我可以在程序中設置一個默認值，它顯示得很好。（或得到一個隨機數，增量這是所有的工作，所以我不需要任何意見在這個。AS3長時間發送給arduino？

但是我需要從Flash到Arduino獲得一個長的值（以及它的動作4位數這可以是int但似乎arduino不讀這個，因爲它是8位）

但我似乎無法找到如何將此轉移到我的arduino，我嘗試了不同的事情，我總是有混合的結果任何人都可以指出我在做什麼錯？

代碼從AS3（這是相關的，只要我認爲），下面的Arduino

    socket.addEventListener(ProgressEvent.SOCKET_DATA, onSocketData); 

    //disable until we connect 
    this.enabled = false; 

    //this is important! If you dont set this to 
    //little endian, then Arduino wont understand 
    //the bytes 
    socket.endian = Endian.LITTLE_ENDIAN; 

    socket.connect("127.0.0.1", 5331); 

function onConnect(evt:Event):void 
{ 
    //get the number that the user input 
    var out:Number = Number("1200"); 

    //write it as a float to the server. 
    //this is important. 
    //socket.writeByte(1200); 
    socket.writeByte(109); 
    socket.flush(); 
    //if number is too big, then it will overflow on 
    //the Arduino, and probably come back as 0.00000 
} 

function onClose(evt:Event):void { 

} 

function onError(evt:Event):void { 


} 

function onSocketData(evt:ProgressEvent):void { 
var msg:String = ""; // create a buffer 
    while (socket.bytesAvailable) { // while there is byte to read 
     var byte:int = socket.readByte(); 

      msg += String.fromCharCode(byte); // else, we add the byte to our buffer 

    }   
    trace("data:" + msg); 
}

我使用serproxy使這些2通信。

我現在又裝起來（我有這個問題了一段時間），現在我看到的Arduino默認值（N）不斷復位，我從閃存發送數據後。數據總是1。

我很想知道爲什麼和我在做什麼錯。

可以使用例如寫長篇['BigInteger'] （https://code.google.com/p/as3crypto/source/browse/trunk/as3crypto/src/com/hurlant/crypto/rsa/BigInteger.as?r=3）從as3crypto，或['LongInt'] （https://code.google.com/p/lodgamebox/source/browse/trunk/com/lordofduct/util/LongInt.as）from lodgamebox – fsbmain

嗯，有趣的話題！我搜索了三個舊項目，我看到的只有這個：'_socket.writeUTFBytes（data）; _socket.flush（）;'，其中數據是** String **。說實話 - 我不記得爲什麼，但它總是一個字符串表示，總是UTF。或者你不想投？我可以分享的另一件事是我們用來讀取數據的方式 - 使用分隔符，因爲有時候只有部分包可以到達（但這是另一個話題）。 –

我明白了，我知道如何發送字符串等，但是有沒有什麼機會讓你有一個很好的例子，如何在Arduino上閱讀它？ –

是否串行速度匹配的serproxy和Arduino的草圖？

parseInt()不處理二進制數據的工作，預計數字爲ASCII字符：「1」，而不是1

嘗試採用Socket類的字符串方法之一來發送數據，例如：

socket.writeMultiByte("125" , "us-ascii") ; 
socket.flush();

也嘗試手動輸入數據到以下草圖的串口監聽怎麼看parseInt()作品：

int n = 401;//display value, this value will be displayed, can be changed 
boolean new_val = true ; 

void setup() { 

    Serial.begin(9600);   // set up Serial library at 9600 bps 
    // This check is only needed on the Leonardo: 
    while (!Serial) { 
     ; // Wait for serial port to connect. Needed for Leonardo only 
    } 
    delay(100) ; 
    Serial.println("Started") ; 
} 

void loop() { 
    serialEvent(); 

    if (new_val) { 
     Serial.print("n: "); Serial.println(n , DEC) ;  
     new_val = false ; 
    } 

    delay(200) ; 
} 

void serialEvent() { 
    while(Serial.available() > 0) { 
     int c = Serial.parseInt(); 
     if (c != 0) { 
      n = c; 
      new_val = true ; 
     } 
    } 
}

我會在家裏試試！我猜是有道理的。 –

那麼如果他發送0作爲數字呢？：P –

好問題。根據Stream :: parseInt的源代碼：'return 0;如果超時，則返回零。我不知道如何區分超時值和零值。這是一個幸福的地方 - 不要碰!!! :)。 –
