求助：如何通过Arduino按钮控制Flash AS3跳转指定帧

我已经完成了Flash AS3控制Arduino的功能，相关源码如下。现在需要实现反向控制：当按下Arduino引脚13连接的按钮时，让Flash跳转到并停止在帧1或帧2，恳请技术帮助。

现有可正常运行的代码 #

Flash端Arduino连接代码（AS3） #

import flash.net.Socket;

var _socket:Socket = new Socket();
var _proxyAddress:String = "127.0.0.1";
var _proxyPort:uint = 5331;
_socket.addEventListener(Event.CONNECT, onConnect);
_socket.connect(_proxyAddress, _proxyPort);
      
function onConnect(event:Event):void{
        trace("Socket Connected");
    }

Flash控制Arduino开关的帧代码（AS3） #

// 帧1代码
MovieClip(root)._socket.writeUTFBytes("f");
MovieClip(root)._socket.flush();

// 帧2代码
MovieClip(root)._socket.writeUTFBytes("n");
MovieClip(root)._socket.flush();

Flash按钮控制代码（AS3） #

onBtn.addEventListener(MouseEvent.MOUSE_DOWN,btn1);
function btn1(evt:MouseEvent):void
{
    gotoAndStop(1);
}

offBtn.addEventListener(MouseEvent.MOUSE_DOWN,btn2);
function btn2(evt:MouseEvent):void
{
    gotoAndStop(2);
}

Arduino端代码 #

#define BULB 13
int incoming = LOW;

void setup(){
Serial.begin(57600);
Serial.println("INITALIZING");
pinMode(BULB, OUTPUT);
Serial.println("READY");
}

void loop(){
  
if(Serial.available () > LOW ){
incoming = Serial.read();

if(incoming == 'n'){
digitalWrite(BULB, LOW);
}
else if(incoming == 'f'){
digitalWrite(BULB, HIGH);
}

  }
}

一、Arduino端代码修改 #

给引脚13连接按钮（建议使用内部上拉电阻简化接线），修改代码检测按钮状态并向串口发送帧跳转指令：

#define BULB 13
#define BUTTON_PIN 13  // 按钮连接至引脚13
int incoming = LOW;
int lastButtonState = HIGH;  // 内部上拉初始为高电平
int currentButtonState;
int targetFrame = 1;  // 初始跳转目标帧

void setup(){
  Serial.begin(57600);
  Serial.println("INITALIZING");
  pinMode(BULB, OUTPUT);
  pinMode(BUTTON_PIN, INPUT_PULLUP);  // 启用内部上拉电阻
  Serial.println("READY");
}

void loop(){
  // 保留原有的Flash控制Arduino逻辑
  if(Serial.available () > LOW ){
    incoming = Serial.read();
    if(incoming == 'n'){
      digitalWrite(BULB, LOW);
    }
    else if(incoming == 'f'){
      digitalWrite(BULB, HIGH);
    }
  }

  // 检测按钮状态，发送帧跳转指令
  currentButtonState = digitalRead(BUTTON_PIN);
  if(currentButtonState != lastButtonState){
    delay(50);  // 按键消抖
    currentButtonState = digitalRead(BUTTON_PIN);
    if(currentButtonState == LOW){  // 按钮按下时电平为低
      // 交替发送帧1、帧2指令
      Serial.print(String(targetFrame));
      targetFrame = targetFrame == 1 ? 2 : 1;
    }
    lastButtonState = currentButtonState;
  }
}

二、Flash端（AS3）代码修改 #

给Socket添加数据接收监听，处理Arduino发来的指令实现帧跳转：

import flash.net.Socket;
import flash.events.ProgressEvent;
import flash.events.Event;

var _socket:Socket = new Socket();
var _proxyAddress:String = "127.0.0.1";
var _proxyPort:uint = 5331;
_socket.addEventListener(Event.CONNECT, onConnect);
_socket.addEventListener(ProgressEvent.SOCKET_DATA, onDataReceived);  // 新增数据接收监听
_socket.connect(_proxyAddress, _proxyPort);
      
function onConnect(event:Event):void{
        trace("Socket Connected");
    }

// 处理Arduino发来的指令
function onDataReceived(event:ProgressEvent):void{
    var receivedCmd:String = _socket.readUTFBytes(_socket.bytesAvailable);
    trace("Received from Arduino: " + receivedCmd);
    // 根据指令跳转对应帧
    switch(receivedCmd){
        case "1":
            gotoAndStop(1);
            break;
        case "2":
            gotoAndStop(2);
            break;
    }
}

关键注意事项 #

• 按钮接线：一端接引脚13，另一端接GND（因启用内部上拉，无需额外电阻）
• 确保串口波特率统一：Arduino、Flash代理工具均设为57600
• 确认Flash代理工具正常转发串口数据至指定端口5331
