  +--tinyvm.rcx.Sensor

public class Sensor

extends Object

Abstraction for a sensor. Example:

   Sensor.S1.activate();
   Sensor.S1.addSensorListener (new SensorListener() {
     public void stateChanged (Sensor src, boolean value) {
       if (value)
         Sound.beep();
     }

     public void stateChanged (Sensor src, int value) {
       LCD.showNumber (value);
       for (int k = 0; k < 10; k++) { }
     }
   });

Field Detail

S1

public static final Sensor S1

Sensor 1.

S2

public static final Sensor S2

Sensor 2.

S3

public static final Sensor S3

Sensor 3.

Method Detail

addSensorListener

public void addSensorListener(SensorListener aListener)

Adds a sensor listener.

NOTE 1: You can add at most 4 listeners.
NOTE 2: Calling this method will result in the creation of a non-daemon thread (one per sensor at most), i.e. your program will not terminate on its own.
NOTE 3: Synchronizing inside listener methods could result in a deadlock.

activate

public final void activate()

Activates the sensor. This method should be called if you want to get accurate values from the sensor. In the case of light sensors, you should see the led go on when you call this method.

passivate

public final void passivate()

Passivates the sensor.

readRawValue

public final int readRawValue()

readBooleanValue

public final boolean readBooleanValue()

readPercentage

public final int readPercentage()

readSensorValue

public static int readSensorValue(short aCode,
                                  byte aType,
                                  byte aMode)

Low-level API for reading sensor values.

Parameters:

aCode - Sensor ID (0x1000 + num_in_rcx - 1).

aType - 0 = RAW, 1 = TOUCH, 2 = TEMP, 3 = LIGHT, 4 = ROT.

aMode - 0x00 = RAW, 0x20 = BOOL, 0x40 = EDGE, 0x60 = PULSE, 0x80 = PERCENT, 0xA0 = DEGC, 0xC0 = DEGF, 0xE0 = ANGLE. Also, mode can be OR'd with slope (0..31).
