Post your ideas for new miscellaneous programs here, or build on ideas posted by other visitors.

I don't know if any of the programs I am going to suggest exist (I am getting tired of searching and not coming up with anything. :)). It would be nice to have an on-calculator assembly compiler for the TI-83 where you could write a program (in assembly language) and compile it to run on the TI-83. I would prefer it wrtten in BASIC, ASM for Ion, or ASM needing the launcher (Send(9prgm(insert program name here)). I would also like it to write the programs for Ion (if possible). If not write them for the Send(9prgm(insert program name here).

The other program that would be nice to have would be a TI-83+ to TI-83 BASIC converter for Windows. Once again, in BASIC, ASM for Ion, or ASM (using Send(9prgm(insert program name here)).

I would be very greatful if somebody could either write working version of either (or both) of these or find working versions on the net.

Thanks :)

I would like to make a correction in my previous message...

Disregard the sentence after the one about the TI-83+ to TI-83 BASIC converter. I was tired and therefor screwed up.

Thanks :)

There's an on-calc assembler app for the 83+ in the archives (but you said 83 :( ), and ZAC-an on-calc assembler for the 86-maybe someone could make a port of it......

I am developing this cool project; it involves several different levels of skill / knowledge.
If you are interested, or DONT HAVE TIME, or DONT CARE, or DONT KNOW ANYTHING, check it out anyway; the is NO excuse not to; it rocks!!!!!

I fit under the "don't have time" and "don't care" categories.

harsh, but true

I have an idea: to connect a usb pen drive for a pc (aka flash cards) to a ti-89. With this application you could increase your memory at least at 32MB. These devices are cheap (about $30) and fast in transmission.

The problems to solve are:

- How to connect an usb device in ti-89 serial port
- How to read the information stored in the pen drive: create a 'mounter' for the filesystem, then to manage the archives.

If anyone want to help me, it would be awesome!.

Thanks.

There are plenty of high-end microcontrollers with USB 2.0 capabilities-just connect one of them between the pen drive and the 89's link port, then write a program for the 89 to communicate with the microcontroller and get it to fetch files from the pen drive through the USB link. The hard part would be the firmware for the microcontroller ;).

Can't you just use the Graphlink?

no.....

Why not?

I haven't looked at the actual hardware, but USB is a complex thing-there would be at least a microcontroller between the USB port and the link port....not the kind of thing you can easily send data through in a direction it's not meant to go....besides, the calc couldn't keep up the clock speed for recieving data.

I do two-way comm between the calc and computer all the time.

He's talking calc to USB card...something you can store info on in a little USB device that fits in your pocket...Dell and many other companies make them for transferring data between computers

Yes, that's the point. The SilverLink allows use of USB by a TI calculator. You can store data on a USB keychain from a TI calculator if you have a driver. This is possible. That's all I'm saying.

USB uses 5 wires at 11 Mbps and the link port uses 3 at 9Kbps. Pen drives usually have 64kB sectors transmitted in a single packet. The usb root hub that resides in your computer polls devices for their device id, initializes them, and requests their communication type and approximate bandwith usage. This sounds like it needs a separate processor to handle coms, but it could probably be done using a program to initialize the device that resides on the calculator with an external device to buffer the 5 lines, demultiplex to 3, and step down the voltage so an application could communicate. A tsr program could then monitor the buffer to see if their is ay activity on the line. The buffer should have at least 64kB of memory to capture the serial data packet if it knew it was comming. This setup should enable the TI to communicate with most usb devices if the proper drivers were used, but it requires the use of external memory, pretty much defeating the purpose for memory. You might have better luck trying to program the new TI84's port instead.

The idea is not to need a PC to share information between the pendrive and the calc. I want to use the pendrive as a external storage device usable with the calculator. Now I found a book about USB architecture. Maybe on my vacations (january - march) I read something.

You wouldn't. There would be a driver on the calc to connect to the pen.

Does anyone know how to send an 83+ OS from a computer? Sorry, I know that this isn't a program idea and is very off-topic, but I've looked through the graphlink help, I've looked at TI's website, I've done web searches, and I can't find anything!!!!

You should be able to just double-click the OS file from Windows if you have TI Connect installed. You might have to associate the file type with the TI Connect .exe, though. I'm not sure since I installed mine a while ago.

Oh, I don't have TI connect-I guess that's my problem. Thanks!!!!!!!!!!!! :)

Sorry to be asking for help on the wrong message board again, but when the transfer was ~42% done, the transfer stopped and some text appeared on my calc's screen-"ERROR! Press any key to turn unit off, then turn unit on again". I did that, and it had another message-"Waiting...send calculator software now". I tried sending the OS again, but when TI Connect established a connection, it displayed the error screen again! I've tried pulling every single battery in the thing and leaving it, and nothing changes! Is there a jumper or something to reset the flash? Is my calc unrecoverable? (This is what I like about my '86-the OS is in ROM and I know that no matter what happens, I can always reset everything by pulling the batteries :| ).

Please?? Someone??? Anyone know what's going on with my calc??

Okay, try these things:

1. Try again. Make sure cable is tight at all connection spots and you have a good copy of the OS.

2. If that doesn't work, you can always send the OS via another calculator. This usually goes a little faster than from the computer, too!

And by the way, there is nothing to reset flash. If you try upgrading and it messes up, you cannot use it until you successfully send the OS.

Hope this helped!

Thanks....I tried it a few more times from the computer and it didn't work, so I'm going to try and get a friend to send the OS from his/her calc.

Not that anyone will be interested, or even read this comment, but I finally revived my calc by sending the OS from a virtual 83+ in VTI, avoiding the need to approach another human *hides behind computer*. THANK YOU RUSTY!!!!
