arduino和flash的as3连接
本帖最后由 桐桐 于 2012-5-18 09:18 编辑以前arduino和flash的链接flash端都是as2编的，但是现在大家都用as3了，所以前段时间学习了一下arduino和flash的as3连接。
下面程序实现的功能是点击flash上的按钮，arduino上就会开始闪灯，并接受arduino上发来的数据。再点击flash上的按钮，闪灯结束，并接受arduino上发来的数据。
——————————————————————————————————————————————
首先放上Arduino端代码：#define LED_PIN 13
#define TOGGLE_LED_STATE 't' //定义一个来自Flash端的联系字符，随意定，与Flash端一样就可以
#define EOL_DELIMITER "$" //定义一个发送字符结束标记，也随意定
int incoming = 0; //定义一个变量，用于接收数据时用
boolean shouldBlinkLED = false; //是否闪灯值，初始为不闪
void setup()
{
Serial.begin(9600);
Serial.print("INITIALIZING");//连接上电脑时发送一个字符串
Serial.print(EOL_DELIMITER);
pinMode(LED_PIN, OUTPUT);
blinkLED(5); //arduino刚连上电脑时闪灯5下
Serial.print("READY"); //发送“ready”到电脑端
Serial.print(EOL_DELIMITER);
}
void loop()
{
if(shouldBlinkLED) //如果闪灯，就闪灯一下
{
blinkLED(1);
}
if(Serial.available() > 0) //如果arduino接受到电脑端来的字符
{
incoming = Serial.read(); //变量incoming就等于受到的字符
if(incoming == TOGGLE_LED_STATE) //假如收到的字符与定义的字符相同
{
shouldBlinkLED = !shouldBlinkLED;//转变闪灯值，如果闪灯就变不闪，不然相反
Serial.print("LED BLINK STATE: "); //同时发送字符串"led blink state:"
if(shouldBlinkLED) //假如正在闪，发“on”
{
Serial.print("ON");
}
else
{
Serial.print("OFF"); //否则发"off"
}
Serial.print(EOL_DELIMITER);
}
}
}
//下面是闪灯程序，这就不解释了
void blinkLED(int count)
{ for(int i = 0; i < count; i++)
{
digitalWrite(LED_PIN, HIGH);
delay(500);
digitalWrite(LED_PIN, LOW);
delay(500);
}
}

下面是Flash端代码，建一个FlashBlink.as文件package
{
import flash.events.Event;
import flash.display.Sprite;
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 FlashBlink extends Sprite
{ private static const TOGGLE_LED_STATE:String = "t";//定义一个与arduino联系字符
private static const EOL_DELIMITER:String = "$";//定义一个结束字符，注意与arduino上一样
private var _socket:Socket;
private var _proxyAddress:String = "127.0.0.1";
private var _proxyPort:uint = 5333;
public function FlashBlink()
{
addEventListener(Event.ADDED_TO_STAGE, onAddedToStage);
}
//下面代码是在画一个方块按钮，并且定义点击按钮时运行程序onclick
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);
s.x = 50;
s.y = 50;
s.addEventListener(MouseEvent.CLICK, onClick);//点击时运行onclick程序 //下面的程序是与arduino建立连接，如果连接上了怎么样，如果断了怎么样等等
_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);
}
//连接上了执行
private function onConnect(event:Event):void
{
trace("Socket Connected");//连接上就发送一个消息
}
private var buffer:String = "";//定义一个字符串缓存字符
//下面程序师接受来自arduino的数据，一个字母一个字母接收的
private function onSocketData(event:ProgressEvent):void
{
var data:String = _socket.readUTFBytes( _socket.bytesAvailable );
buffer += data;
var msg:String;
var index:int;
//下面是把接受到的字符拼起来
while((index = buffer.indexOf(EOL_DELIMITER)) > -1)
{
msg = buffer.substring(0, index);
buffer = buffer.substring(index + 1);
trace("Message Received from Arduino : " + msg);
}
}
//下面就是onclick程序，就是点击按钮时要做的
private function onClick(event:MouseEvent):void
{
trace("onClick");
if(!_socket.connected) //假如没有连接上，发送你要连什么的
{
trace("You must be connected to send a command to the Arduino.");
return;
}
_socket.writeUTFBytes(TOGGLE_LED_STATE);//如果没有不连接上，就发联系字符给arduino
_socket.flush();//发送
}
//下面定义关掉arduino时，显示Socket Closed
private function onClose(event:Event):void
{
trace("Socket Closed");
}
//下面是出错时显示的消息的
private function onIOError(event:IOErrorEvent):void
{
trace("IOErrorEvent : " + event.text);
}
//下面也是出错时的
private function onSecurityError(event:SecurityErrorEvent):void
{
trace("SecurityErrorEvent : " + event.text);
}
}
} 上次的程序是点击按钮时来触发arduino做一些动作以及接受数据的，这次测试一下让arduino连续的发送数据，让flash来接受，并通过在flash的文本框里实时显示。

arduino端的程序
#define LED_PIN 13
#define TOGGLE_LED_STATE 't'
#define msgstop 's'
#define EOL_DELIMITER "$"
int incoming = 0;
int i=0;
int in=0;
void setup()
{
Serial.begin(9600);
Serial.print("READY");
Serial.print(EOL_DELIMITER);
}
void loop()
{
if(Serial.available() > 0) //如果收到数据
{
incoming = Serial.read();
if(incoming== TOGGLE_LED_STATE) //如果收到的是开始代码
in=1; //变量in=1；
if(incoming==msgstop) //如果收到的是结束代码
in=0; //in=0；
}
if(in==1)
{Serial.print(i); //发送一个变化的值i
Serial.print(EOL_DELIMITER);//发送结束字符
i++; //值i递增1
}
else
{ Serial.print("off "); //如果受收到结束代码，发送off
Serial.print(EOL_DELIMITER);
}
delay(100); //没100毫秒发一个
}
以下是flash 端，flash端分两部分，一部分是getshu.as类里面的程序，如下：package
{
import flash.events.Event;
import flash.display.Sprite;
import flash.display.MovieClip;;
import flash.net.Socket;
import flash.events.IOErrorEvent;
import flash.events.ProgressEvent;
import flash.events.SecurityErrorEvent;
import flash.utils.Endian;
import flash.events.MouseEvent;
public class getshu extends MovieClip
{
public static var ardmsg:String;
private static const TOGGLE_LED_STATE:String = "t";
private static const msgstop:String = "s";
private static const EOL_DELIMITER:String = "$";
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 var i:Number;
private function onClick(event:MouseEvent):void
{
trace("onClick");
if(!_socket.connected)
{
trace("You must be connected to send a command to the Arduino.");
return;
}
//下面是点击按钮时发送开始字符，再点击发送结束字符
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里的代码，建立一个动态文本框，命名为armsg，下面是帧代码addEventListener(Event.ENTER_FRAME,onEnterFrame);
function onEnterFrame(event:Event):void{
armsg.text="";
armsg.text=getshu.ardmsg;
}
结果，点击按钮，文本框里开始显示动态变化的数字，来自于arduino
serproxy or others ?
电脑端用serproxy 本帖最后由 qykings 于 2013-12-5 14:01 编辑
IOErrorEvent : Error #2031: Socket Error. URL: 127.0.0.1
flash 连接不上arduino
明了，，我没有加serproxy做代理
flash是连上serproxy了，
FlashBlink.swf - 解压缩后为 2,751 个字节
Socket Connected
我就没有收到arduino返回的任何数据
arduino代码
int temp=Serial.read();
Serial.println( temp );
Serial.print("fromarduino");
Serial.flush();
我用arduino自的工具可以看到有输出
是怎么回事啊
