Programming Limit Switch

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.

Re: Programming Limit Switch

Initialize limit switches as a digital input:

Code:

DigitalInput switch = new DigitalInput(channel)

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

Code:

if(switch.get()) doSomething();

See this thread.

Re: Programming Limit Switch

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.

Code:

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:

Code:

Button limitSwitchButton = new DigitalIOButton(1);

limitSwitchButton.whenPressed(new limitSwitchCommand());

Even simpler.
