I am using LeJOS NXJ 0.7 and NetBeans 6.5 on Vista with Bluetooth. All my environment variables and classpath variables are fine.
About 50% of the time when I am uploading files to the brick, it freezes up and I get the clicking sound. I'm not sure where to begin looking for a reason why.
Here's the program (super simple first iteration):
- Code: Select all
import lejos.nxt.*;
/**
* A program that operates on the Lego NXT Brick
*
* @author Christopher
*/
public class MainClass {
private final TouchSensor touch;
public MainClass() {
touch = new TouchSensor(SensorPort.S1);
SensorPort.S1.addSensorPortListener(new TouchListener());
}
public void run() {
Motor.A.forward();
while (Motor.A.isMoving()) {
}
}
public static void main (String[] args) {
MainClass test;
// System.out.println("Press the Orange button to begin");
// Button.waitForPress();
test = new MainClass();
Motor.A.getTachoCount();
test.run();
}
private class TouchListener implements SensorPortListener {
public void stateChanged(final SensorPort arg0,
final int oldValue,
final int newValue) {
if (newValue < 900) {
System.out.println("Press the Orange button to continue");
Button.waitForPress();
Motor.A.stop();
}
}
}
}
And here's my build file:
- Code: Select all

My template.properties file:

nxj.library.path=${env.NXJ_HOME}/bi
Does anyone have any suggestions? Thanks in advance,
