The problem was that Arcade Drive was running in Teleop.vi and Tank Drive was running in Robot Main.vi

Im guessing Arcade Drive is originally in Teleop.vi because we never put it there.
Anyways, we fixed the problem. The error was that the power cable was not properly connected to the Digital Sidecar.

I just read your post. We have been doing the same thing with a servo, but with two preset positions and a button to toggle between them.

Here's a picture of our code:

I put this in a sub-vi, called from teleop.vi. Two controls in teleop.vi are used to set the two angles of the servo. When you get them where you want, either make the current value the default value, (right-click and select Data Operations) or replace them with a constant of the same value. The green, boolean wire comes from the joystick button where it breaks out from the unbundle block.



The Flip-Flop.vi is used to latch the button. I found the VI here on CD a while back, posted by one of the NI people. I don't recall the name or exact post, but it's been quite useful, once I made a few modifications to simplify it for our use.

Thanks, but we have already solved this problem by wiring axis 3 of joystick 3 to the Camera Set Position. It is much simpler code.
