Re: Encoder resolution on fast turning shafts
If you look at "roboRIO Specifications" linked from here (https://decibel.ni.com/content/docs/DOC-30419), in the Digital I/O section on page 4, it references "minimum pulse width". That's the...

Re: Encoder resolution on fast turning shafts
While much of that discussion still holds to some extent, much of it is not all that applicable given the roboRIO's vastly faster DIO, unless you have a blindingly fast encoder signal.
The roboRIO...

Re: Encoder resolution on fast turning shafts
The roboRIO FPGA can track encoder edges at 25 ns from edge to edge. It will also calculate and report rates at the same resolution. I suspect this is more capability than any team needs, but I'm...

Re: GRIP/Labview compatibility?
The LabVIEW vision support has shipped with Vision Builder AI for years. GRIP is not compatible with LabVIEW, but VBAI has and continues to serve the same purpose as GRIP now does for Java and C++.

Re: Got Gyro drift? Try Sensor Fusion !
If you actually installed the FRC update then you would have these VIs. You could then use those VIs to understand the API that FRC uses so that you can port to the other USB I2C API.
I would...

Re: Failed to Deploy, File Permission Error
How interesting. I just started seeing this too - but in the 2016 beta. We'll get to the bottom of it, but in the mean time, you can work around it by going to a Linux shell and changing the owner of...

Re: Labview Challenge 3
I threw together a quick starting point for the interaction with a board UI. There is no game logic behind it, just the board itself.
Hope that helps.

Re: Labview keeps messing up ethernet settings
This is all old news. You never have indicated what version of LabVIEW or the driver station you are running, but from the evidence, it is at least a year old.
When you provide details it helps...

Re: Brownout behavior - alternative design goals
That's contradictory and not how it will work. And anyway, if you have no comms how does FMS disabling do any good. You have no comms.
No, we will continue to have the designed behavior that the...

Re: Brownout behavior - alternative design goals
The point of having it "high" at 6.8 V is to have some breathing room to get those loads turned off in time for the battery to recover before the controller blacks out. Since we don't have control...

Hi Tom,
I think this is a perfect example of where your robot has a better chance to operate reliably using the new functionality, but the control software needs to pay attention to the info...
