reading a usb signal (eclipse to processing)

in Android Processing • 8 months ago

Hi guys,

Looking to read (just read not send back and forth) a signal that will be coming in via the usb connection on my galaxy SIII, found this -

http://developer.android.com/guide/topics/connectivity/usb/host.html - on the android developer website that should contain everything I need, but I'm having some trouble determining how to get anything from java format to processing. Also curious if I need to change the manifest or if one of the android->sketch permission check boxes might do this for me.

I think I am supposed to use the UsbAccessory class and then the UsbRequest classes. If anyone has had any experience with these, any guidance would be much appreciated.

package buildingiot.heartrate;



import java.io.IOException;



import android.app.Activity;

import android.os.Bundle;

import android.util.Log;

import android.widget.TextView;



import org.microbridge.server.Server;

import org.microbridge.server.AbstractServerListener;



public class HeartRateOnCloudActivity extends Activity {



// Create TCP server (based on MicroBridge LightWeight Server).

// Note: This Server runs in a separate thread.

Server server = null;



int heartrate = 0;



TextView textView1;



/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);



textView1=(TextView)findViewById(R.id.textView1);



//Create TCP server (based on MicroBridge LightWeight Server)

try {

server = new Server(4568); //Use the same port number used in ADK Main Board firmware

textView1.setText( "Starting server.." );

server.start();

textView1.setText( "server started!" );



} catch (IOException e){

Log.e( "Seeeduino ADK" , "Unable to start TCP server" , e);

textView1.setText( "server not started!!" );



}



server.addListener( new AbstractServerListener() {



@Override

public void onReceive(org.microbridge.server.Client client, byte[] data){

textView1.setText( "got arduino data!" );

String bpm = new String(data);

textView1.setText(bpm+ " bpm" );



}

});



}
