Problem with LabView Update 3.2 #2
 
:yikes: We installed LabView update 3.2 and when we downloaded our code which was working with 3.0 the digital side car did not put out any pwm signals??? The rest of the digital side car worked. We had DIO inputs from the line sensors and compressor switch working. And the relay outputs to the compressor worked as well. Only the PWM signals were not functioning. I didn't have a scope to check the pwm signals but the Jaguars and the victors didn't see any. Is this a problem with the FPGA crio load?? Help.
Thanks
Tom

I just installed LabView Update 3.2 #2, and now LabView won't run at all. When I try to launch it, it says "Unable to open resource files." This is a horrible time to have no LabView! Suggestions anyone?

The FPGA did not change with 3.2, only NetConsole changed.

That seems to mean you tried to run the update from within the .zip file.

Uncompress everything and run it again.

We've heard of this happening when Windows decides to update in the middle of your FRC install. Usually running the FRC update again fixes it. I'm curious how you run the FRC update. Do you unzip it to a folder, and then run the installer?

I'm having this same problem and the same error message pops up every time I try to install the 3.2 update. I also cannot roll back to 3.1

Exactly how are you installing it?

By extracting everything from the .zip archive and running Autorun.

I'll just reinstall LabVIEW.

Problem wasn't with the update at all. Learned about the DriveSafteyUpDate.VI. The TeleOp.VI wasn't running fast enough.::rtm::

I'm sorry to say this, but we had the same problem and the way we fixed it is to reinstall labview. also remember to extract the update before running it.

We had to remove some code that was measuring a Potentiometer in a while loop inside the teleop.vi The code wasn't running fast enough for the WPI_RobotDriveSafetyUpdate.vi to get the update signal that resets it so it disables all PWM signals. Then the Jag's/Victors see no control and disable their oututs. I think...

Re: Problem with LabView Update 3.2 #2
 
Can you post your code? In general, it is a bad practice to put while loops in the Teleop.vi for the reason you mentioned. When we implement sensors we normally put these in a "Sensors" While Loop in Periodic Tasks, with about a 20-40 ms wait.
