Right click on the "Buttons" cluster -- Go to the "Cluster Pallette -- Click unbundle -- wire that to the Button out -- wire to the button you want.

Hope that helps.

Here's a bit more of a visual in case you're using the basic framework (Pretty much what DHR2o said):

Go to your palette and go to "WPI Robotics Library" > "DriverStation" > "Joystick" and add a "Get.vi" .. hook it up to the connector shown below:


Go to your palette and go to "Programming" > "Cluster, Class & Variant" and add an "Unbundle by name". Hook it up to the pink output of the get VI as shown below:



Now from the cluster outputs you have access to all of the buttons.


Good luck!

Thanks, me and the other programer found a salution but this is alot better.

wait, what's the difference between using get and get raw for the buttons?

[TotalChaos]

As far as the buttons go, nothing. The only difference I know of is the joystick axis output ranges from like -30000 something to +30000 something in increments of 256 or 512 or something around there...

The joystick ranges from -1 to 0 to 1. If it is scaled to 127 (which it is set to by default) then the joystick ranges from -127 to 0 to 127. Which gives you a more finer control over a motor.

Ah, that's right... When I wrote that I was thinking about the preseason when we had a joystick hooked up to the computer directly and got input through the computer... My bad.

what is the joystick axis output?? it is really -1 to 1??? or is it 0 to 256 or -158 to 158

-1 to 1. If you have a running system, don't forget that in LV you can open the panel and watch the values as they flow through. Many times that is a good way to understand the values being sent.

I want to program in a way that when i press the trigger the motor works at half speed...
I don't know how to do it.. I did a little bit of the steps that were mentioned above and it really didn't help. So can you tell me how to do it??
If you can provide pictures with that I would really appreciate..
Thank you..
