Constructor Detail

RgbSensor

public RgbSensor()
          throws java.io.IOException,
                 com.pi4j.io.i2c.I2CFactory.UnsupportedBusNumberException

Throws:

java.io.IOException

com.pi4j.io.i2c.I2CFactory.UnsupportedBusNumberException

Method Detail

getReading

public RgbSensor.ColorReading getReading()
                                  throws java.lang.Exception

Throws:

java.lang.Exception

getNormalizedReading

public RgbSensor.ColorReading getNormalizedReading()
                                            throws java.lang.Exception

Throws:

java.lang.Exception

readingToHue

public java.awt.Color readingToHue(RgbSensor.ColorReading cr)

setWhitePoint

public void setWhitePoint()
                   throws java.lang.Exception

Takes a reading and sets that to the color point 255,255,255. Raw readings will not be altered, but normalized readings will be scaled assuming the current white point.

Throws:

java.lang.Exception - If hardware failure during reading process

setGain

public void setGain(int gain)
             throws java.io.IOException

Sets the gain (hardware amplification) of readings.

Parameters:

gain - amount of amplification

Throws:

java.io.IOException - If there is a hardware I/O error
