Autonomous questions (Labview) and some general issues

[Daniel_H]

I can't get the autonomous to work, when I switch from TELEOP to AUTO at the DS, nothing happens. Could it be my very simple autonomous test code?
here's my code:



btw, should I remove all controls and indicators from the VI if I want to use the robot not connected to the PC?

Thanks!

all i know is most programs in labview don't work until they are within a while loop,(so you can control them from the dash board) trying creating a while loop to execute when in autonomous mode. If you use a case statement, that is fine, but the control panel won't see that their is anything to run the program with, it needs a while loop to run in labview, idk about in the cRIO.

Are you clicking the run button on Basic Robot Main.vi or Autonomous Independent.vi? I don't believe that the Autonomous Ind VI will run on its own. I think that everything needs to be setup by using Basic Robot Main.vi as the highest-level VI (especially Ethernet comm).

I click RUN at the Basic Robot Main.vi

I changed very few from the original autonomous code

do you mind if i start working with dx/dt for the joysticks, that is an amazing idea

go ahead, and tell me your findings

I already got it working, but didn't implement it on traction control yet. I want to add some inertia to the controls to improva acceleration, since sudden fulls on the joysticks will make you slip

I haven't started on traction control, I'm still working on ballistics, and tracking. But 3d calculus is giving me a headache so I'll see what i can come up with.

Labview can do trig right?

You don't need to remove the controls and indicators before building and deploying as a startup application. I don't believe that these will impact the final performance at all when running as a startup app since the "compiler" will strip off the UI goodies when unnecessary.

I'd recommend that you set some breakpoints in Autonomous Independent.vi and see if the application actually jumps to that VI when you toggle the switch on the DS. Maybe the changes that you've made to Basic Robot Main.vi have somehow defeated Autonomous Independent.vi. For example (and I haven't dug deep enough into the architecture to know whether this is easily accomplished), an infinite loop in teleop may never let the main state machine jump to Auto Ind VI.

What's shown on the DS screen when you switch to Auto?

somehow it is toogling teleop to auto again, but it still needs to be connected to the PC and running, otherwise nothing happens.

[Russ Beavis]

In order to run without your development PC attached, you need to build the app, deploy and set it to "run as startup".

All teams should check out the above link. It's the complete (IMHO) LabVIEW for FRC guide and includes instructions for deploying and running.

If the above link breaks for some reason, the document can easily be accessed through FIRST's Control System portal at http://www.usfirst.org/community/frc....aspx?id=10934 (see LabVIEW Robotics Programming Guide).

Hitting the run button only loads the program into RAM. You will need to build->deploy->run as startup for it to persist.

Do you mean that I never really wrote a code that would be there after I reboot the cRIO? omg

I think I didn't understand how to do that. Where are those commands?

[Jon236]

There is an entire section in the manual which Russ referenced which goes over building, then deploying an application. Try it out.....it's easy. At least you didn't lose your code.
