Re: timer task with multiple pulse input pins

[Paul Johnson]

One more question. When I connect to the IOIO board with this code both 
lines of text show the same numbers and do not return to 0 when the wire is 
unhooked from the pin. Also numbers continue to display for probably 10 
times the amount of time the pin was connected. 

Please see the video. The pin was just plugged in for a second. (only one 
pin). Anyone see what I am missing?

Thanks for the help with the code. I think its starting to come together.

class  PulseInputThread extends Thread {
 private final PulseInput input_;
  private final Timer timer_;
  
 public PulseInputThread(PulseInput input,Timer timer) {
 input_ = input;
    timer_ = timer;
}

 
 private synchronized void read() throws ConnectionLostException {
    TimerTask task = new TimerTask() {public void run() {
     interrupt();
  }};
  
    timer_.schedule(task, 1000);
    try {
      last_ = 1/input_.waitPulseGetDuration();
      task.cancel();
    } catch (InterruptedException e) {
      last_ = 0;
    }
  }
 
   public void run() {
    try {
      while (true) {
        read();
      
        try {
Thread.sleep(1000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
      }
    } catch (ConnectionLostException e) {
     e.printStackTrace();
    }
  }

public synchronized float getLastReading() {
    return last_;
  }
 }
  class Looper extends BaseIOIOLooper {
 PulseInputThread thread1_;
PulseInputThread thread2_;
 @Override
protected void setup() throws ConnectionLostException {
 PulseInput   input1_ = ioio_.openPulseInput(new DigitalInput.Spec(1), 
ClockRate.RATE_62KHz,  PulseMode.POSITIVE, false);
PulseInput  input2_ = ioio_.openPulseInput(new DigitalInput.Spec(3), 
ClockRate.RATE_62KHz,  PulseMode.POSITIVE, false);

 Timer t = new Timer();
   thread1_ = new PulseInputThread(input1_, t);
   thread2_ = new PulseInputThread(input2_, t);
  thread1_.start();
  thread2_.start();
 }

 @Override
public void loop() throws ConnectionLostException {
  setText1(thread1_.getLastReading());
  setText2(thread2_.getLastReading());
 try {
Thread.sleep(1000);
} catch (InterruptedException e) {
}
}
 public void disconnected() {
   try {
 
     thread1_.join();
     thread2_.join();
   } catch (InterruptedException e) {
   }
}
 }



@Override
protected IOIOLooper createIOIOLooper() {
return new Looper();
}

private void setText1(final float freqHZ1) {
runOnUiThread(new Runnable() {
@Override
public void run() {
 row1.setText("Seeds per second: " + freqHZ1);
 }
});
}
 private void setText2( final float freqHZ2) {
runOnUiThread(new Runnable() {
@Override
public void run() {
 row2.setText("Seeds per second: " + freqHZ2);
 }
});
}
