This revolutionary piece of hardware marks a rennaissance of the TI Community. From this day forward shall we not be silent and stagnant. Let this event mark a new day for all programmers our there! Program my friends, and may the force be with you...

Hats off to Cerrato Renaud, for you, my friend, have sparked a revolution in the TI Community and we shall now from this day be reborn. Everyone should begin programming to celibrate this momentous occasion.

Thank you.

I turn around TI community since 1998. Now, i'm an Electronic Engineer, the community give me many things, so i wonder what i can do for it ? And voilą.

I repeat, all is ok on my 2 TI92 (1.12i and 2.1) and TI89, but i need more testers to report any bugs.

Thank to all community, and David Ellsworth too ;)

um, just how easy is "easy?" like "can be programmed in basic" easy or "needs asm" easy?

The programming isn't the part that scares me, it's the electronics, the hardware stuff...

that, my friend, is the truth

This schematic is actually quite simple. Compared to, say, Sami Khawam's IR Link, this is VERY simple. I will probably make an attempt at this.

There is no programming required because of the PIC microcontroller. It works the same way as a normal cable link.

Yes ! I repeat : It work as a real TI Cable. Fully tested with my TI92 (Rom 1.12i and 2.1) and TI89.

I wait for futures testers to report any bugs.

It will work with all TI (from TI83 to V200), but i need testers.

Send confirmation to nono240@altern.org

Is it possible to convert the program to a PIC16F84 instead? I was gonna get one of those for Sami Khawam's [http://sami.ticalc.org/] PIXPander.

No way. 16F84 doesn't have hardware UART. It's not possible.

Is the PIC16F876 Re-programmable? If so, by UV rays, or automatic Re-programming through the programmer?

of course. Electrically programmable and erasable.

Thank you. See link for a good site.

Nevermind, it doesn't exist anymore.

There is nothing to be programmed. The whole thing should work like a standard link cable- of course, it needs to be tested on other types of calcs to make sure.

Well, this is all nice and great, but its not that practical. Why don't we just start from scratch and realize that its almost impossible for these calculators to do true networking with more than 2 parties. Hell, if you are so intent on that happening just make your own software.

It IS possible to network the caculators!
It can be done rght now!
the current meathod of networking calculators is to connect them all to internet connected PC's and use the currently existing TCP/IP calculator programs.
But that does work, so it is known that multiple calculatr networks are possible, but so far are hard to build, and not worth the effort, however a little inovation *will* fix this, granted that file sending will not work on such a network using the normal ti-protocol, but the upgradable calcs can share files over a network using the ti-navigator protocol.

NO!!! You are missing the point!!! By the time that we make an actual way for this to work, its gonna be pointless. Also, the capabilities do nothing if no one writes for it because its too innefficent. I mean,logically, we've seen how fast the link cable goes, and it wouldn't be good for gaming, even IM would be pretty sluggish. Also, the thing is, this network would probably not have enough distance to be useful. And, the fact that the data port on the calculators IS A ONE WAY PORT destroys whatever practicality there was...

Wait a minute... I doubt calculator data ports are one way. Wouldn't that mean you could only send data or only receive it? (Oh, sorry, I can't send you my games... I've got the Ti-83+ RECIEVE-ONLY model.) That makes no sense at all!

My thoughts exactly... wonder what he's talking about.

Sorry. I had 2 1/2 hrs of sleep last night, so I've been barley awake all day. It is a 2 way port from how you're talking, but what I meant was that info can only go 1 way @ once. It would have made sence if I had elaborated more.

Scratch that. You all are just defective... :p jk lol

Actually, I'd have to check on wether or not it would be considered that or not. I know that it couldn't be considered a full-duplex port, but I doubt that it could be considered technically a one way port... It falls logically in a partial-duplex, but something just tells me that its not that but its a 2 way port. I think that theres an actual difference...

it is a half-duplex port, send or recieve at any given instance.

OK. Thats what I thought. Well, thats what I think that I thought.

Oh, I give up... LOL

Oh, that's why you made that comment at the first page ;-)

Which first page?

WHAT DO YOU MEAN THERES ONLY 1 FIRST PAGE????
Damn you people are defective... lol

Yes. That is why.

LOL, nice touch of sarcasm/humour. BTW I'm glad something else link this has come out for linking. Plan games against your friends on the other side of class, YEAH!

Ooh! And chat and share answers! I love TI calcs... I used them to cheat on the Bio and History finals. Yeah.

I put a periodic table on it for the AP Chem test. Perfectly legal too. A couple of my friends were very suprised I was allowed to do that and wern't too happy. As far as I know I was one of only a few who passed the test, so a 3 is good enough.

It's so easy to put a study guide in a text file and use the calc on the test. Of course, in subjects where you don't use calculators (Bio, History), it's harder. Those are the subjects I do worse in... I wonder if there's a coorelation.

I do good in all subjects where I can't use a calculator, which is all subjects anyway. My math teacher is amazing and he doesn't let us use calculators so that we don't become lazy. We're also the best math school in the state, if not the nation.

whats the school?

Longfellow.

And it should read "one of the best middle schools in math..."

I live in virginia.

I do good in everything where I have good teachers. If I have a good teacher <i wish ticalc had italics>AND</i wish ticalc had italics> a calc, well, in math I got a 105% on the final (not bad for playing games all class, every class).

If I had the same stuff, I'd get a 100, which is the highest I can get...

i took the ap chem test this year and i don't think that any programs on my 89 would have helped at all. i haven't gotten my score back yet but i should hopefully be getting it very soon.

I think I got mine on Sunday. One of my friends hasn't recieved theirs either, so your not the only one.
