Sorry for my lack of knowledge, but what would the pins allow you to do? What's the advantage to having them?

And happy for turning a bot into an FPS sim!

These pins allow teams to make their own custom buttons to control robot functions.

There are eight digital inputs, eight digital outputs, as well as four analog inputs.

Oh right, that makes sense. So this eliminates the need to making your own ghetto port or anything? What kinda of connection dealys are we gonna have to put together to put the switches/buttons/what-have-you onto the pins?

Nothing special You can just use the same standard 3-pin connector used for PWM cables.

That's what I figured, and those don't take that long to wire. So each connection needs the ground, the 5v supply and the signal. I'm slowly learning this stuff! Now if only I could program better... =P

As opposed to 16 digital inputs, 16 analog inputs, and 8 LED digital outputs on the old system.

I like the ease of connectivity. I dislike losing so many OI I/O points - especially the digital inputs. This may limit what we can do on the button box. You can never have enough pushbuttons, rocker, and toggle switches. We often wire spares up to support future use applications developed as the season progresses.

Switching the joysticks over to USB will help offload some of what we used to wire to the digital and analog inputs, but I still feel we'll be a bit lacking for button box I/O.

However, perhaps we can use a laptop keyboard to take up the slack - who wants to create some custom keyboard overlays for FIRST robots? That would be kinda fun.

In the end, though, I'd rather just rely upon the simple pushbuttons and switches wired to the digital in's - tradition is a good thing, as Bill Gates may decide to intervene and not let us operate our "laptop button box". That would not be fun - Bad, Bill, bad!

You could always pick up a gameport to USB converter at the RadioShack or simiar and use that to provide the additional inputs you want. The loss of LED outputs is harder to counter though... no more HUDs, I guess.

Presuming the hardware works as advertised out of the gate, with no flaky behaviour (Canadian in honour of 1114 celebratory week)....

I'm thinking I'll create a 15-pin D-SUB to PWM-style breakout harness for the analog ins just so I can still go old school in the event of any "newfangled geewhiz" USB flakiness. A tribute to the past.

No I'm not very trusting. Always have a backup plan....

I wonder how much current the 8 digital outputs can drive? What would you use them for otherwise?

I don't know about the digital outputs, but standard USB specifications state that each port must be capable of supporting at least 100 mA of current, with the option to sink as much as 500 mA. Any unused USB ports, with the addition of some transistors on the digital outputs, should provide enough power for other things.

My god, that new driver station is... So, pretty...


Pretty...

Great info!
