Take a look at the provided examples. From the main LabVIEW FRC 2012 screen, click the Support tab, then click "Find FRC Examples..." In the "FRC Robotics" folder, you will see several examples in the "Pneumatics" subfolder. One or more of them should help you.

i'm not sure, but it doesn't seem like you understand the task that we want to do. We have this catapult mechanism that we want to launch with a pneumatic system, so a quick burst of air, as opposed to a slow, strong air pressure.

Here (http://www.slideshare.net/oregonfirs...pneumatics2012) is a great resource for a beginner learning pneumatics. It explains the mechanical side of things and should give you an insight on what you need to do. If you need clarification on some of the points made in the slideshow, just ask

That can't be solved in programming, that problem is purely physical. We are limited in terms of valve orifice size and working pressure as well as the number of valves we can use per cylinder port (one, max). The only remaining way to do what you want to do would be either to use a spring assist, at which point the cylinder would actually slow you down, which isn't good, or you could use multiple small cylinders each fed off of its own solenoid valve.

we have a solenoid that worked last year and doesnt this year but in a weird way. when programmed as a double solenoid, the double solenoid does not work on any of the plug-ins. but programed as singles, only one side works. you switch the plug-ins of the two sides and the opposite side is the only one that works. is this a programming, wiring, or some other problem and any ideas on how to fix it? help would be appriciated
