public final class LEDPhidget

extends Phidget

This class represents a Phidget LED. All methods to control a Phidget LED are implemented in this class.

The Phidget LED is a board that is meant for driving LEDs. Currently, the only available version drives 64 LEDs, but other versions may become available so this number is not absolute.

LEDs can be controlled individually, at brightness levels from 0-100.

Method Detail

getCurrentLimit

public int getCurrentLimit()
                    throws PhidgetException

Returns:

Current Limit

Throws:

PhidgetException - If this Phidget is not opened and attached, if the index is out of range, or if unsupported by this board. See open for information on determining if a device is attached.

setCurrentLimit

public void setCurrentLimit(int currentLimit)
                     throws PhidgetException

Sets the current limit for all outputs. This is only supported by some PhidgetLEDs - see the product manual.

Returns:

Voltage

Throws:

PhidgetException - If this Phidget is not opened and attached, if the index is out of range, or if unsupported by this board. See open for information on determining if a device is attached.

setVoltage

public void setVoltage(int voltage)
                throws PhidgetException

Parameters:

voltage - Voltage

Throws:

PhidgetException - If this Phidget is not opened and attached, if the index is out of range, or if unsupported by this board. See open for information on determining if a device is attached.

public int getLEDCount()
                throws PhidgetException

Returns the number of LEDs that this board can drive. This may not correspond to the actual number of LEDs attached.

Returns:

number of LEDs

Throws:

PhidgetException - If this Phidget is not opened and attached. See open for information on determining if a device is attached.

getDiscreteLED

public int getDiscreteLED(int index)
                   throws PhidgetException

Returns the brightness value of an LED. This value ranges from 0-100.

Parameters:

index - LED

                           int brightness)
                    throws PhidgetException

Sets the brightness of an LED. Valid values are 0-100, with 0 being off and 100 being the brightest. This 0-100 value is converted internally to a 6-bit value (0-63) so only 64 levels of brightness are actually possible.

Parameters:

index - index of the LED

brightness - desired brightness of this LED

Throws:

PhidgetException - If this Phidget is not opened and attached, or if the index of brightness value are out of range. See open for information on determining if a device is attached.
