Constructor Detail

TetrixMotorController

public TetrixMotorController(I2CPort port,
                             int daisyChainPosition)

Instantiate a HiTechnic TETRIX Motor Controller connected to the given port and daisy chain position.

Parameters:

port - The sensor port the controller (if daisy-chained, the first) is connected to.

daisyChainPosition - The position of the controller in the daisy chain.

Throws:

java.lang.IllegalStateException - if a Motor Controller was not found with given port and daisyChainPosition

Method Detail

getBasicMotor

public TetrixMotor getBasicMotor(int motorID)

Get a TetrixMotor instance that is associated with the motorID.

Parameters:

motorID - The motor ID number. This is indicated on the HiTechnic Motor Controller and is represented using MOTOR_1 or MOTOR_2.

Returns:

The TetrixMotor instance

Throws:

java.lang.IllegalArgumentException - if invalid motorID

java.lang.UnsupportedOperationException - if motorID has already been used for a Tetrix motor instance other than TetrixMotor.

See Also:

TetrixMotor, getEncoderMotor(int), getRegulatedMotor(int)

getEncoderMotor

public TetrixEncoderMotor getEncoderMotor(int motorID)

Get a TetrixEncoderMotor instance that is associated with the motorID. The motor must have an encoder installed for a TetrixEncoderMotor instance to work correctly.

Parameters:

motorID - The motor ID number. This is indicated on the HiTechnic Motor Controller and is represented using MOTOR_1 or MOTOR_2.

Returns:

The TetrixEncoderMotor instance

Throws:

java.lang.IllegalArgumentException - if invalid motorID

java.lang.UnsupportedOperationException - if motorID has already been used for a Tetrix motor instance other than TetrixEncoderMotor.

See Also:

TetrixEncoderMotor, getBasicMotor(int), getRegulatedMotor(int)

getRegulatedMotor

public TetrixRegulatedMotor getRegulatedMotor(int motorID)

Get a TetrixRegulatedMotor instance that is associated with the motorID. The motor must have an encoder installed for a TetrixRegulatedMotor instance to work correctly.

Parameters:

motorID - The motor ID number. This is indicated on the HiTechnic Motor Controller and is represented using MOTOR_1 or MOTOR_2.

Returns:

The TetrixRegulatedMotor instance

Throws:

java.lang.IllegalArgumentException - if invalid motorID

java.lang.UnsupportedOperationException - if motorID has already been used for a Tetrix motor instance other than TetrixRegulatedMotor.

See Also:

TetrixRegulatedMotor, getBasicMotor(int), getEncoderMotor(int)

getVoltage

public float getVoltage()

Return the current battery voltage supplied to the controller.

Returns:

The current battery voltage in volts
