Read any sensor on NXT 2

[Danny Meier]

Hi,

I tried to read any kind of sensors using my NXT 2 brick. Either the result is always 0 or I get a StackOverflowException (e.g. using the Sonar sensor)

Code example for Ultrasonic sensor (produces a StackOverflowException):

                var brick = new Brick<Sensor, Sensor, Sensor, Sensor>("usb");
                brick.Connection.Open();
                
                var test = new Sonar(SonarMode.Centimeter);
                brick.Sensor4 = test;
                Console.WriteLine(test.ReadDistance());
                brick.Connection.Close();

Code example for Touch sensor (reads always 0)

                var brick = new Brick<Sensor, Sensor, Sensor, Sensor>("usb");
                brick.Connection.Open();
                
                var test = new TouchSensor();
                brick.Sensor1 = test;
                Console.WriteLine(test.Read());

In any case the IsInitialized property is always false. Also calling test.Initialize() doesn’t change anything.

Can you try it with the following code:

var brick = new Brick<Sensor, Sensor, Sensor, Sensor>("usb");
brick.Connection.Open();

brick.Sensor1 = new TouchSensor();
Console.WriteLine(brick.Sensor1.ReadAsString());

Reads all the time 0. Independent whether I press the button or not.

Can you try Bluetooth?
