As announced in several recent news articles, CALCnet2.2 is a long-running project of mine that has in the past two weeks reach fruition on real hardware devices. NetPong v1.0 is a small game that I have been developing for the last few days to showcase the capabilities of CALCnet 2.2, including broadcasting, one-to-many and one-to-one transmissions, fault and collision tolerance, and low latency capabilities. NetPong allows you to play Pong across an arbitrary number of calculators. With two, three, four or more calculators, NetPong creates a single virtual LCD for a standard Pong game, complete with scoring, paddles, distributed pausing and quitting, and more. Although no specialized hardware is required, playing with more than two calculators requires a simple splice of I/O cables together; feel free to ask here on the forums for assistance with that.

CALCnet2.2 will continue to be developed, and I plan to soon re-integrate it into Doors CS 7, no mean feat considering how little free space is left in it for me to add new features. I'll let the somewhat unwieldy screenshots of two-, three-, and four-calculator gameplay speak for themselves.

NetPong v1.0

Now that's some great work Kerm! Can't wait to see what else is possible!

ahh, finally, a beta!

Now, I think it is time to test on my nspire in a bit... I will post results



I tested it on the nspire

needless to say, it didnt work

Thanks comicIDIOT! I'm very excited about it, and am also looking forward to all the possible applications of this.

Argh, how so? The Nspire never saw the other calculator?

oh, no

the both reconize each other, but the calculator is position number 1 will freeze and I will have too reset RAM or all MEM

It will freeze when you press [ENTER] to start the game, you mean? Hmm, that's interesting. It doesn't behave the way the Nspire does when it executes an illegal instruction, does it?

No, but a very interesting peice of info

while the "one" position calc is frozen, pressing on and off a few times will cause a full reboot on teh nspire and a RAM clear on the TI-84+SE

How weird! The Cn2.2 interrupt catches poweroff, so it should allow you to turn on and off indefinitely while it waits for data. What if you hold down [CLEAR] while the Nspire appears frozen?

Nothing.. that is how I know it is frozen, clear does nothing to the calculator

Meh, that's a pain. I'll have to investigate this further, because I'd love for CALCnet2.2 to work properly even on the Nspires.

I'm at school right now and my AP Computer Science class is in love with this.... Just sayin.

That's great to hear. You should convince them all that they should be using Doors CS 7, and give them my regards for liking CALCnet.

HA, good luck with that

Yeah, I know it's far-fetched, but I'd still like to pull it off. I guess I need to treat myself to an Nspire one of these days.

it would save me alot of trouble ()

I suppose, but I'd probably still want your confirmation of things working or failing.

yeah, probably

Good, it's always nice to have other sets of eyes than my own looking into these things. I probably would have missed about 80 to 90% of the bugs that you guys found for me in Doors CS.

could someone direct me to the page where it shows you how to make the spliced cords for this?

I'm actually going to put up a tutorial for it. You have two cords and you want to splice them into a four-port network? If I were to post detailed instructions, would you be able to take decent photos of the process for me to include in the tutorial?
