Programming Limit Switch

[OwenVanTiem]

I am the programmer for my team, and I am curious how to program a limit switch. I cant seem to find any documentation or code snippets elsewhere on the internet.

Initialize limit switches as a digital input:
DigitalInput switch = new DigitalInput(channel)

To check if a switch is closed or not, use the get() method:
if(switch.get()) doSomething();

See this thread. (http://www.chiefdelphi.com/forums/showthread.php?t=114318)

What Signet said.

Also, if you ware using the Command Based structure with Java you can set the limit switch up to act as a button to fire a command.

final DigitalInput limitSwitch = new DigitalInput(1);
Button limitSwitchButton = new Button() {
public boolean get() {
return limitSwitch.get();
}
};
limitSwitchButton.whenPressed(new SomethingCommand());

Actually there is already a class for this in WPILib: DigitalIOButton.

So you just need:

Button limitSwitchButton = new DigitalIOButton(1);
limitSwitchButton.whenPressed(new limitSwitchCommand());

Even simpler.
