Persistieren von Sensordaten

[tinytinkerer]

Hallo zusammen,

ich soll Sensordaten vom RED-Brick persistieren. Kann mir da wer weiterhelfen? Ich stehe gerade voll auf dem Schlauch.//Edit hat sich erledigt:

 

package com.company;

import com.tinkerforge.IPConnection;
import com.tinkerforge.BrickletAccelerometer;

import java.io.*;

public class Main {
    private static final String HOST = "localhost";
    private static final int PORT = 4223;

    // Change XYZ to the UID of your Accelerometer Bricklet
    private static final String UID = "Cge";

    // Note: To make the example code cleaner we do not handle exceptions. Exceptions
    //       you might normally want to catch are described in the documentation
    public static void main(String args[]) throws Exception {
        IPConnection ipcon = new IPConnection(); // Create IP connection
        BrickletAccelerometer a = new BrickletAccelerometer(UID, ipcon); // Create device object

        ipcon.connect(HOST, PORT); // Connect to brickd
        // Don't use device before ipcon is connected

        // Add acceleration listener
        a.addAccelerationListener(new BrickletAccelerometer.AccelerationListener() {
            public void acceleration(short x, short y, short z)  {

                PrintWriter outputfile = null;
                try {
                    outputfile = new PrintWriter((new BufferedWriter(new FileWriter("Beschleunigung.txt",true))));
//replace your System.out.print("your output");
                    outputfile.println(+x/1000.0+";"+y/1000.0+";"+z/1000.0+";");
                    outputfile.println("");
                }catch (IOException ioe) {
                    ioe.printStackTrace();
                }finally {
                    if (outputfile != null){
                        outputfile.flush();
                        outputfile.close();
                    }
                }
            }
        });

        // Set period for acceleration callback to 1s (1000ms)
        // Note: The acceleration callback is only called every second
        //       if the acceleration has changed since the last call!
        a.setAccelerationCallbackPeriod(1000);

        System.out.println("Press key to exit"); System.in.read();
        ipcon.disconnect();
    }
}

OK, ich versteh dafür dein Problem nicht. Daten können einfach auf die SD geschrieben werden oder bei Bedarf auf einen externen Speicher.

Problem gelöst.
