Trouble getting encoder output to work with analog trigger sources

[vamfun]

Hi all,
We are using two analog ports on RoboRio to read a grey hill encoder. We set up some analog triggers which tested ok by themselves. When we try to use them as DigitalSource objects for the WPI encoder class it doesn't seem to work.

Does anyone have some C++ code examples of driving encoder software with analog triggers?

We tried something like the following without success.

public class Robot extends IterativeRobot {
...
AnalogInput input1 = new AnalogInput(1);
AnalogInput input2 = new AnalogInput(2);

AnalogTrigger Trigger1 = new AnalogTrigger(input1);
AnalogTrigger Trigger2 = new AnalogTrigger(input2);

AnalogTriggerOutput source1 = new AnalogTriggerOutput(Trigger1,AnalogTriggerType.kRi singPulse);
AnalogTriggerOutput source2 = new AnalogTriggerOutput(Trigger2,AnalogTriggerType.kRi singPulse);

Encoder enc = new Encoder(source1,source2);

* This function is run when the robot is first started up and should be
* used for any initialization code.
*/
public void robotInit() {


Trigger1.setLimitsVoltage(1.5,3.5);
Trigger2.setLimitsVoltage(1.5,3.5);

/**
* This function is called periodically during operator control
*/
public void teleopPeriodic() {

val = enc.Get();


I know .... this isn't our actual code but its representative.
Any ideas??
