public class DVS128
extends AERetina
implements java.io.Serializable

Describes DVS128 retina and its event extractor and bias generator. This camera is the Tmpdiff128 chip with certain biases tied to the rails to enhance AE bus bandwidth and it achieves about 2 Meps, as opposed to the approx 500 keps using the onchip Tmpdiff128 biases.

Two constructors ara available, the vanilla constructor is used for event playback and the one with a HardwareInterface parameter is useful for live capture. setHardwareInterface(net.sf.jaer.hardwareinterface.HardwareInterface) is used when the hardware interface is constructed after the retina object. The constructor that takes a hardware interface also constructs the biasgen interface.

Constructor Detail

DVS128

public DVS128()

Creates a new instance of DVS128. No biasgen is constructed for this constructor, because there is no hardware interface defined.

DVS128

public DVS128(HardwareInterface hardwareInterface)

Creates a new instance of DVS128

Parameters:

hardwareInterface - an existing hardware interface. This constructer is preferred. It makes a new Biasgen object to talk to the on-chip biasgen.

Method Detail

getDescription

public static java.lang.String getDescription()

setHardwareInterface

public void setHardwareInterface(HardwareInterface hardwareInterface)

overrides the Chip setHardware interface to construct a biasgen if one doesn't exist already. Sets the hardware interface and the bias generators hardware interface

Overrides:

setHardwareInterface in class Chip

Parameters:

hardwareInterface - the interface

setAeViewer

public void setAeViewer(AEViewer v)

Description copied from class: AEChip

Sets the AEViewer that will display this chip. Notifies Observers of this chip with the aeViewer instance.

Overrides:

setAeViewer in class AEChip

Parameters:

v - the viewer
