Constructor Detail

IRSeekSensor

public IRSeekSensor(SensorPort port)

Creates a sensor instance connected to the given port.

Parameters:

port - the port where the sensor is plugged-in

IRSeekSensor

public IRSeekSensor()

Creates a sensor instance connected to port S1.

Method Detail

getValue

public GenericIRSensor.IRValue getValue()

Polls the sensor. The channel corresponds to the port where the sensor is plugged-in: Port S1:channel 1...Port S4:channel 4.

Returns:

the current value as IRValue defined in GenericIRSensor

getIntValue

public int getIntValue()

Polls the sensor. The channel corresponds to the port where the sensor is plugged-in: Port S1:channel 1...Port S4:channel 4. The returned value has the bearing value in bit 0..7 (augemented by 64 to get only positive values) and its distance value in bits 8..15.

Returns:

the current value as integer
