各位好心朋友，帮帮我好吗？关于processing和arduino问题
各位好心的朋友们，帮帮我好吗？我想快点解决这问题。是这样的，最近这几天研究这processing和arduino互动的问题，总是不成功的。我在processing写了一些代码，processing和arduino的串口都是COM4，可是，在arduino下，就出现这问题就出现以下的一串java错误。
processing.app.SerialException: 串口'COM4'在使用中。尝试退出任何可能在使用它的其他程序。

希望大家帮帮我解决。万分感谢！
arduino代码：

pinMode(StepperA2, OUTPUT);
pinMode(StepperB1, OUTPUT);
pinMode(StepperB2, OUTPUT);
pinMode(penPin,OUTPUT);//Pen motor pin as a output
pinMode(paperPin,OUTPUT);//Paper motor pin as a output
back(80);//makes the car return, to be sure it will start at the begin of the line
}
void loop() {
if(Serial.available()){//if there is data on the Serial buffer
while(Serial.available()>0){//continues reading the values on the buffer.
data=Serial.read();
if(data==1){
dot();//if a one was received, makes a dot.

}

pullPaper();//call the pulling paper function.
back(80);//return the car.
}
}
}

void pullPaper(void){ //function to pull the paper

}
processing代码是：
import processing.serial.*;
Serial myPort;// Create object from Serial class
PImage IMG; //create a PImage named IMG
void setup() {
size(60, 118);//Put here the size of your image
String portName = Serial.list();
myPort = new Serial(this, "COM4", 9600);//opens the Serial Port
IMG = loadImage("link2.jpg");//Open your image, put here the name of your image, including the extension.
image(IMG, 0, 0);
}
void draw() {
IMG.loadPixels();
for (int y = 0; y < height; y++) {//check the lines
for (int x = 0; x < width; x++) { //check each pixel in the line
int loc = x + y*width; //the pixels are loaded as in a aray, so its position is only a number.
if (IMG.pixels>color(128)) {
myPort.write(0);//if a pixel is not black, send a '0'.
delay(50);
}
else {
myPort.write(1);//if a pixel is black, send a '1'.
delay(50);
}
}
delay(10000);//Wait for some time, time enough to the printer finish this line.
myPort.write('L');//send a "L" to indicate a new line.
}
noLoop();
}
把 myPort = new Serial(this, "COM4", 9600);//opens the Serial Port
改成 myPort = new Serial(this, portName,9600);//opens the Serial Port
看看 打开注册表HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Control/COM Name Arbiter
把ComDB删除后重新尝试即可!(注:这样会重建所有COM口)。重启电脑！ 275891381 发表于 2014-12-11 09:54 static/image/common/back.gif

按你方法后正常，但是不知道processing情况下怎样才算是正常 cjhhao1 发表于 2014-12-11 21:04 static/image/common/back.gif

写个简单的程序 西安测试一下通信正常不不就知道了
