Arduino與Flash的連接需要一個(gè)serproxy的程序
serproxy.cfg文件需要修改，用記事本打開(kāi)如下
# Config file for serproxy
# See serproxy's README file for documentation
# Comm ports used
comm_ports=5 //這個(gè)是你的Arduino連接到電腦上后對(duì)應(yīng)的com端口號(hào)，如果大于10，要修改到小于10的
# Default settings
comm_baud=9600
comm_databits=8
comm_stopbits=1
comm_parity=none
# Idle time out in seconds
timeout=300
# Port 1 settings (ttyS0)
net_port5=5333 //這個(gè)是發(fā)送到flash端的號(hào)碼，要與Flash端arduino.as文件中相對(duì)應(yīng)
————————————————————————————————————————————————
在Arduino端發(fā)送需要代碼如下：
Serial.print(變量名);
Serial.print(0,BYTE);//以發(fā)送空字節(jié)結(jié)束
——————————————————————————————————
falsh端接受首先需要Arduino.as文件，然后flash里需要代碼如下（現(xiàn)在還只搞定了actionscript2，還沒(méi)有搞定actionscript3）
var a:Arduino = new Arduino(5333);
a.addEventListener("onConnect",aListener);
a.addEventListener("onConnectError",aListener);
a.addEventListener("onDisconnect",aListener);
a.addEventListener("onReceiveData",aListener);
//接收Arduino的數(shù)值
aListener.onReceiveData = function(evtObj:Object){
//取得Arduino的值
var ArduinoInt = evtObj.data
artm=ArduinoInt; //將來(lái)自arduino端的數(shù)據(jù)賦值給變量artm
}
----------------------------------------------------------------
上次的程序是點(diǎn)擊按鈕時(shí)來(lái)觸發(fā)arduino做一些動(dòng)作以及接受數(shù)據(jù)的，這次測(cè)試一下讓arduino連續(xù)的發(fā)送數(shù)據(jù)，讓flash來(lái)接受，并通過(guò)在flash的文本框里實(shí)時(shí)顯示。

arduino端的程序
#define LED_PIN 13
#define TOGGLE_LED_STATE 't'
#define msgstop 's'
#define EOL_DELIMITER "$"
int incoming = 0;
int i=0;
int in=0;
void setup()
{
}
void loop()
{
if(Serial.available() > 0)
{
incoming = Serial.read();
if(in==1)
{
}

以下是flash 端，flash端分兩部分，一部分是getshu.as類里面的程序，如下：
package
{
import flash.events.Event;
import flash.display.Sprite;
import flash.display.MovieClip;;
import flash.net.Socket;
import flash.events.IOErrorEvent;
import flash.events.ProgressEvent;
import flash.events.SecurityErrorEvent;
import flash.utils.Endian;
import flash.events.MouseEvent;
public class getshu extends MovieClip
{
private static const TOGGLE_LED_STATE:String = "t";
private static const EOL_DELIMITER:String = "$";
private var _socket:Socket;
private var _proxyAddress:String = "127.0.0.1";
private var _proxyPort:uint = 5333;
public function getshu()
{
addEventListener(Event.ADDED_TO_STAGE, onAddedToStage);
}
private function onAddedToStage(event:Event):void
{
removeEventListener(Event.ADDED_TO_STAGE, onAddedToStage);
var s:Sprite = new Sprite();
s.graphics.beginFill(0x00FF00);
s.graphics.drawRect(0,0, 200,100);
s.graphics.endFill();
addChild(s);
//position it
s.x = 50;
s.y = 50;
s.addEventListener(MouseEvent.CLICK, onClick);
_socket = new Socket();
_socket.addEventListener( Event.CONNECT, onConnect );
_socket.addEventListener( Event.CLOSE, onClose );
_socket.addEventListener( ProgressEvent.SOCKET_DATA, onSocketData );
_socket.addEventListener( IOErrorEvent.IO_ERROR, onIOError );
_socket.addEventListener( SecurityErrorEvent.SECURITY_ERROR, onSecurityError );
_socket.endian = Endian.LITTLE_ENDIAN;
_socket.connect(_proxyAddress, _proxyPort);
}
private function onConnect(event:Event):void
{
trace("Socket Connected");
}
private var buffer:String = "";
private function onSocketData(event:ProgressEvent):void
{
var data:String = _socket.readUTFBytes( _socket.bytesAvailable );
buffer += data;
var msg:String;
var index:int;
while((index = buffer.indexOf(EOL_DELIMITER)) > -1)
{
msg = buffer.substring(0, index);
buffer = buffer.substring(index + 1);
trace("Message Received from Arduino : " + msg);
}
ardmsg=msg;
}
private function onClick(event:MouseEvent):void
{
trace("onClick");
if(!_socket.connected)
{
trace("You must be connected to send a command to the Arduino.");
return;
}
//下面是點(diǎn)擊按鈕時(shí)發(fā)送開(kāi)始字符，再點(diǎn)擊發(fā)送結(jié)束字符
if(i==0)
{
_socket.writeUTFBytes(TOGGLE_LED_STATE);
i=1;
}
else
{
_socket.writeUTFBytes(msgstop);
i=0;
}
_socket.flush();
}
private function onClose(event:Event):void
{
trace("Socket Closed");
}
private function onIOError(event:IOErrorEvent):void
{
trace("IOErrorEvent : " + event.text);
}
private function onSecurityError(event:SecurityErrorEvent):void
{
trace("SecurityErrorEvent : " + event.text);
}
}
}
——————————————————————————————
下面是flash里的代碼，建立一個(gè)動(dòng)態(tài)文本框，命名為armsg，下面是幀代碼
addEventListener(Event.ENTER_FRAME,onEnterFrame);
——————————————————————————
結(jié)果，點(diǎn)擊按鈕，文本框里開(kāi)始顯示動(dòng)態(tài)變化的數(shù)字，來(lái)自于arduino
