Using SkypeAPI in Processing

When helping a friend (my previous student) on her final project, I tried to use the SkypeAPI for Java in Processing, and finally got it work in windows XP using Processing 1.0 (Finally ... well I didn't know they released the 1.0 version until last week).

Platform and system specifics:

OS- Windows XP

Processing version- Processing 1.0 (Without Java)

Sun JDK  (NOT JRE!) version- 1.6 rev 11

Skype API for Java- Latest code in tar ball [link]

Skype ver 2.0 or above

Installation steps:

1) Do the usual setup for Processing and JDK, expand the tarball to a new folder.

2) In the sketch folder (in Processing version 1.0 only!), create the following file structure

-- libraries
    -- skype
        -- library
            |-- skype.jar (copy from folder Skype->release)
            |-- swt.jar (copy from Skype->lib->window)
            |-- winp.jar (copy from Skype->lib->window)
            |--libskype.jnilib (copy from Skype->res

  

3) Copy the file skype.dll to c:/windows/system32

4) Start Processing, now you should see an option  for importing skype library in import->libraries

5) Start Skype, test the following code in skype

import com.skype.connector.windows.*;
import com.skype.connector.test.*;
import com.skype.connector.*;
import com.skype.connector.linux.*;
import com.skype.*;
import com.skype.connector.osx.*;
import com.skype.connector.win32.*;

void setup(){
  try{
  Skype.call("+8521878200");
  }catch (Exception e){
    e.printStackTrace();
  }
}

void draw(){
}

Using AT commands + serial port to control mobile phone from processing

import processing.serial.*;

Serial mobilePort;

void setup(){
println(Serial.list());
 mobilePort=new Serial(this, Serial.list()[9], 9600);  
 size(400, 400);
}

void draw(){
  // Expand array size to the number of bytes you expect
  byte[] inBuffer = new byte[7];
  while (mobilePort.available() > 0) {
    inBuffer = mobilePort.readBytes();
    mobilePort.readBytes(inBuffer);
    if (inBuffer != null) {
      String myString = new String(inBuffer);
      println(myString);
    }
  }
  
}

void mousePressed(){
  //make phone calls
  //mobilePort.write("ATD+1878200;");
 // mobilePort.write("\n\r");

 //Anser phone call
 mobilePort.write("ATA;");
 mobilePort.write("\n\r");
}

Hacked serproxy

There's a problem with the serproxy program for connecting ports number over 10. Based on the instructions in the arduino forum, I've recompiled the serproxy that overcome this problem.
