Class Sensor

Direct Known Subclasses:

Gyro, I2c, Light, Light_rcx, Rotation, Sound, Temperature, Touch

class Sensor

Class for analog sensors - also works as the base class for all other sensors

Sensor

public Sensor( Sensor_port port, Connection* connection, Sensor_type sensor_type, Sensor_mode sensor_mode );

Sensor constructor

Parameters:

port - [which sensor port to use]

*connection - [attach a connection]

sensor_type - [set the sensor type]

sensor - mode [set the sensor mode]

~Sensor

public virtual ~Sensor();

get_i2c_address

public virtual unsigned char get_i2c_address();

Get the I2C address (Dummy method does nothing - is implemented in some sub class )

Returns:

the I2C address

get_mode

public virtual Sensor_mode get_mode();

Get the sensor mode

Returns:

the sensor mode

get_port

public virtual Sensor_port get_port();

Get the sensor port

Returns:

the sensor port

get_type

public virtual Sensor_type get_type();

Get the sensor type

Returns:

the sensor type

init

public virtual void init( bool reply = false );

Initiate the sensor (sets its type and mode)

Parameters:

reply - [true = require reply from NXT; false = no reply from NXT]

print

public virtual string print();

Get the sensor reading as a string (init method will be called if the sensor has not been initialized)

Returns:

the sensor reading as a string

read

public virtual int read();

Get the sensor reading (mode dependent) (init method will be called if the sensor has not been initialized)

Returns:

the mode dependent sensor reading

read

public virtual int read( Result& result );

Get multiple sensor readings (Dummy method does nothing - is implemented in some sub classes)

Parameters:

&result - [reference where the sensor readings are placed]

Returns:

1 if sensor readings are placed in &result otherwise 0

set

public virtual void set( unsigned int value );

Set a parameter on the sensor (Dummy method does nothing - is implemented in some sub classes)
