LabVIEW CAN issue

Technical NI LabVIEW
1

We are having a stuttering issue on our robot this year. In our CAN loop, we only have the RoboRIO, two Talon SRXs, the Pneumatics Module, and PDB.

Whenever I press the button to activate the one of the Talons, the lights on the Talon rapidly flash between green and orange. The flashing is so rapid, it makes it quite hard to see. This is indicating that the Talon is getting a signal. I ran a simulation in LabVIEW with probes in the appropriate places (the button output wires and the orange wire going into the “Set Speed”) and all the values are staying consistent.

I am at a loss as to what the issue is. Any help or example Talon SRX CAN code would be appreciated.

Thanks!

Did you read the product’s documentation and examples on the manufacturer’s website?

I am having the same problem it will stutter and then all of a sudden it will go solid orange and then go back to green/red and orange blinking. Could this be a CAN firmware issue?

That’s a good description of the results of a common programming error. It’s likely that you have two different places in your code setting the Talon’s speed, and one of them is setting it to zero while the button is trying to set it to run forward.
