global variables and autonomous independent

[Greg McKaskle]

I think you are wanting to use DS switches to tell the robot what part of the field it is on.

If this is correct, you can read the DS I/O as many times as you like. And it can be stored in a global if that is helpful.

If you only want this info in the autonomous code, the sample code already reads the switch positions and the slider positions on the left. You can use these to tell the robot the field location.

To set the switches, you can either connect the I/O board and attach physical switches using the breadboard or another breakout, or you can leave the I/O board detached and use virtual switches and values onscreen in the I/O tab.

yeah I only want it for the autonomous code. how can I use the code to show the field position? I really have no idea about any of this.

[Greg McKaskle]

One way is to read the analog slider and wire it to the case structure. The value will automatically be converted to an integer and you can add cases for 1, 2, and 3.

Set the slider on the DS, run the autonomous, and put something in your code, like a breakpoint or probe so you can verify the right code is running.

how do I read the analog slider? is it a .vi or something?

[Greg McKaskle]

On the left side of the Autonomous, it calls Get Analog Input.vi. This returns the four sliders from the screen on the DS. If you plug in the I/O board, the board sets the sliders, not the screen.

okay I connected the analog one slot on the get analog in.vi to a case structure surrounding the autonomous code. So now I can just set the slider on the little laptop they sent us and it will convert that to different cases right?

[Greg McKaskle]

Test it and see.

Also check out the "Get Alliance" vi which outputs field position.

I might be mistaken, but I thought that that Get Alliance only shows your DRIVER STATION position, not necessarily your field position.

That is correct. Other than telling you whether you are on the red team or the blue team, Get Alliance does NOT tell you anything about your field position.
