Constructor Detail

PrototypeSensor

public PrototypeSensor(SensorPort port)

Creates a sensor instance connected to the given port.

Parameters:

port - the port where the sensor is plugged-in

PrototypeSensor

public PrototypeSensor()

Creates a sensor instance connected to port S1.

Method Detail

setDIO

public void setDIO(int[] ioControl)

Sets the direction of the 6 digital input/output channels.

Parameters:

ioControl - the direction of each channel. 0: input, 1: output

readAnalog

public void readAnalog(int[] ain)

Reads the sensor. Analog input data 0..1023 are returned in the given ain.

readDigital

public void readDigital(int[] din)

Reads the sensor. Digital input data 0 (corresponds to low state) or 1 (corresponds to high state) is returned in the given din. For digital channels defined as outputs -1 is returned.

setSamplingPeriod

public void setSamplingPeriod(int period)

Sets the sampling period of the ADC (4..100 ms, default 4 ms).

Parameters:

period - the new sampling period

read

public void read(int[] ain,
        int[] din)

Reads the sensor. Analog input data 0..1023 are returned in the given ain, digital input data (0, 1) in the given din. For digital channels defined as outputs -1 is returned.

write

public void write(int[] dout)

Writes the given bit state (low/high) to the digital output channels. Only channels set as output will be affected. Input channel bits are ignored.

Parameters:

dout - an integer array of length 6 that holds the bit state: 0->low, 1->high

addPrototypeListener

public void addPrototypeListener(PrototypeListener prototypeListener)

Registers the given prototype listener.

Parameters:

prototypeListener - the PrototypeListener to become registered.
