Class Sensor14bits

java.lang.Object
  java.util.Observable
      org.lsst.ccs.framework.Module
          org.lsst.ccs.subsystems.fcs.Sensor14bits

All Implemented Interfaces:

Serializable, Observer, org.lsst.ccs.framework.Configurable, Sensor

Direct Known Subclasses:

CanOpenSensor14bits, SimuSensor14bits

public abstract class Sensor14bits
extends org.lsst.ccs.framework.Module
implements Sensor

This class represents an ADC which is a 12bits sensor : the value returned by the sensor is coded with 14 bits, so its value is between 0 and 32760.

Method Summary

int	getMaxValue()
int	getMinValue()
int	getValue() This method returns value if the sensor is not updating otherwise it waits until the update is completed and returns the new read value from the hardware.
void	initModule()
void	setMinValue(int minValue)
void	setValue(int aValue)
String	toString()
void	updateValue() This method updates the sensor value : first it reads a new value from the hardware or from the simulated sensor, then it checks if the value is in the range between minimal value and maximal value.

Method Detail

initModule

public void initModule()

Overrides:

initModule in class org.lsst.ccs.framework.Module

getValue

public int getValue()

This method returns value if the sensor is not updating otherwise it waits until the update is completed and returns the new read value from the hardware.

Specified by:

getValue in interface Sensor

Returns:

value

setValue

public void setValue(int aValue)

getMaxValue

public int getMaxValue()

Returns:

the maxValue

getMinValue

public int getMinValue()

setMinValue

public void setMinValue(int minValue)

updateValue

public void updateValue()
                 throws SensorValueOutOfRangeException,
                        HardwareError

This method updates the sensor value : first it reads a new value from the hardware or from the simulated sensor, then it checks if the value is in the range between minimal value and maximal value. If it's ok it updates the sensor value with the new value, otherwise it throws an exception.

Specified by:

updateValue in interface Sensor

Throws:

SensorValueOutOfRangeException

HardwareError

toString

public String toString()

Overrides:

toString in class Object
