I think that does a pretty good job.

Ahhhh I got it now! Brilliant statement. XD

Fair enough, thanks Merth. I'm glad to hear that you'll be building a hub and learning more about microcontrollers. Smile

Edit: And thanks, 0rac343. Smile
Should be fun. I've only ever used PICAXEs, so it'll be neat to see what all the fuss over Arduinos is about.
Thats a really interesting project you've got. And I must say that this is totally *PWN* . Very Happy

This truly shows your 1337 skillz with anything to do with calculators and electronics.

You flatter me, sir. Smile I have fun with this stuff, so I pursue it when it gets frustrating, and I feel accomplished when I push past through difficulties. I'm sure most of you guys could accomplish similar things with sufficient time and perseverance. Smile

@Merthsoft: Next step is for me to figure out a nice case to put my Arduino and a bunch of sockets/plugs into.
This looks really nice! How would a program detect if the calculator is connected to CALCnet or gCn?

I've used the following method in Flourish, Netpong, and Chat:

1) Each calculator sends periodic broadcast frames
2) When another calculator sees a broadcast from a calculator it doesn't know about, it sends a directed message back to that calculator introducing itself

This allows both calculators to learn about each other. It can be made more elaborate to mimic a TCP/IP 3-way handshake (SYN, SYNACK, ACK). Alternately, you can just add a calculator to your list of known calcs when you get a broadcast from it. I generally do the broadcasting as a discovery phase before a game begins, as in NetPong and Flourish, although for Chat any calculator can be discovered any time.
Thanks for that, that will definitely be useful for my CALCnet game. Very Happy

Awesome. Smile As I said, I'm more than willing to share all of my calculator setup and management code from things like NetPong; I just need to give myself the free time to separate out the code for you.
Hmmm, just wondering, but will the type of USB port that you use affect gCn in any way? (just a random, wondering thought)

As long as it can maintain a 115Kbaud FTDI serial-over-USB connection, I don't think you'll have a problem with USB 1.1 vs. USB 2.0, if that's what you're asking. Smile

As far as progress goes, I'm currently still entrenched in exploring the various glitches that have been cropping up, most at the Arduino end of things.
exactly what I was asking, sorry if I was being a little unclear. Thanks Kerm, I think that is all my questions for now. I will be waiting for the whitepaper I assume you will make (like with CALCnet) Very Happy

Yeah, that's the plan, although I'd like to get more software written first. It seems the timing occasionally goes out of whack on TI-83+s but not TI-84+s, so I'm not sure exactly what that's about.
Not being familiar with an Arduino setup, does your gcnclient interface with the Arduino over some cross-platform generic Arduino driver, or does it require special device drivers on each platform?

It simply connects to the Arduino as a serual device, in the case of the photograph above, COM4 and COM11 for the two different clients. For this particular setup it's serial by way of USB, but that doesn't really make a difference.
So presumably under Unix environments like OS X, and Linux these would be something like /dev/tty.* rather than COMn?

/dev/ttyS[0-9]+, to be specific. Smile I'll need to write all the proper #ifdefs for Linux and Mac compilation though, once I get everything working satisfactorily from the Windows gcnclient.
Good stuff =) Maybe when I'm in NYC we can fiddle about with a Mac build.

Definitely, that would be fun! I'm using a few Windows-specific constructs, but nothing that wouldn't be relatively simple to rewrite for a Mac build, depending on how OS X handles serial ports and sockets.
