cRIO 2015 : NI roboRIO

Let's go with the STEP model. I'll ask that we add a note on the site about file compatibility.

Great, thanks!

Nothing listed for LabVIEW, but I'm sure the NI booth will have info.

I would presume the LabVIEW sessions at 6:00 and 7:00 would include roboRIO information. It would be pretty bizarre to have a workshop focused on programming for the cRIO.

From my understanding, the LabVIEW training sessions are modeled after the presentations posted here: https://decibel.ni.com/content/docs/DOC-33629
These are for the cRIO. The abstracts for the workshops make them sound more like an introduction to the LV development environment, with specific examples / tips pertaining to FRC framework, than new stuff for the roboRIO.

Their FAQ says

When can we purchase a spare roboRIO?
All FRC Teams will get a roboRIO in the Kit of Parts at Kick Off 2015. Teams can purchase a spare roboRIO starting in December 2014 for <$450 (pricing not yet finalized).

Was hoping to have it a little earlier in the fall to play with. More anxious than concerned about working with the new system. Seems like it should be a pretty smooth transition.

Swing by the area around pit admin. You might see something!

WPI is going to have a small demo bot using the new control system at championship. It's really cool.

My favorite part is the new radio, but that bit still isn't finalized.

The 2CAN is also integrated into the roboRIO

Not exactly.

A separtate CAN interface is included on the RoboRio. It is a 2pin signal connector and the roborio has a built in can terminating resistor.

2CAN is not on the Roborio. 2CAN is a standalone product of CTRE.

The Power Distribution Board has the termination resistor, not the RoboRio.

You need a termination resistor on BOTH ends of a CAN network to make it work. The RoboRio has one built in, always connected. The Power Distribution Board (at least the revision the Alpha Testers got) has one built in, connected through a jumper so that it may selectively be selected as the other end of the chain.

Not true.

For Controller Area Networks (CAN) to work properly, both ends of the bus need to be terminated.

This is because communication flows both ways on the CAN bus therefore both ends of the pair of signal wires (CAN_H and CAN_L) must be terminated.

The RoboRio has an internal terminating resistor that can not be removed. This means the RoboRio should always be at one end of the CAN Interface. The PD Board, has a setable terminating resistor by way of a jumper, this means the PD Board can be used at the other end of the CAN interface if the jumper is in place. However, the PD Board does not have to be at the end of the bus, you can remove the jumper and put another device after the PD Board, just make sure to add a terminating resistor to that device.

Hope this helps,
Kevin

My mistake. Still learning about the equipment.

[jt_999]

Does anyone know if the roborio is REQUIRED for the 2015 season, or will we have the option to continue using the cRIO for a year or two?

[Mark McLeod]

It will be required.
The cRIO's will still be compatible and can be used for practice robots.
