Re: roboRIO usb
Quite true. That is the number they list. However, that *is* in excess of the USB 2.0 spec. That number is in line with the USB 3.0 spec, but the port on the RoboRIO isn't listed as a USB 3.x...

Re: roboRIO usb
We've done it. It works fine as long as you don't try to pull too much current from the RoboRIO. 500ma is the max draw on USB 2.0. So, if you're trying to power 3 cameras, for example, you'll...

Re: roboRIO mDNS Problem
In order for Linux to connect with the RoboRIO via the mdns address, you'll need to have the Avahi service running. That's Linux's mdns resolver.

Re: Cameras allowed on the robot
Naturally, you can still use the Axis IP cameras from previous years. However, if you want to use a USB camera, you need to make sure that the camera is Linux UVC compatible. This means just about...

Re: You can't break it, they said. Try, they said.
Hmm... OK, assuming you can get to a mode where port 22 works, log in via ssh (e.g., putty on WinDoze) as "admin" with no password. Once you're in, issue the command "dmesg" and capture the output. ...

Re: Using the TI LaunchPad from your KoP
We've already got a couple more on order from the TI store. We're looking forward to getting some cool controls whipped up as soon as the build team figures out what we're controlling.

Re: PSoC 4 Prototyping Kit, product documentation
Yeah, I saw that the Launchpad can be used for I/O. But, it's not clear if the Leonardo and the PSoC can be used for anything except the "I". There's no mention of the "O" part in any documentation...

Re: PSoC 4 Prototyping Kit, product documentation
