Flash Drives on a Calculator
Posted by Michael on 12 September 2006, 04:43 GMT

[I have mass storage devices on a mass storing calculator!]As the result of a group effort between myself, Brandon Wilson, and Dan Englender, we have released msd8x v0.94, which allows the use of ordinary USB flash drives with a TI-84 Plus. Brandon has been laboring all summer long on finishing the driver and GUI to be acceptable for public usage, and thanks to his dedication and adding of nifty features it is at last at the stage for a general release. Information on downloading and running msd8x can be found at the WikiTI calculator wiki.

With the appropriate cable, you can browse, modify, and copy (in both directions) files between a flash drive and the 84+'s RAM and/or archive. msd8x also supports the running of ION and MirageOS programs directly from a flash drive.

There is, but I think development has somewhat stalled. I'm not really qualified to answer, but I did it anyway. :)

Is it possible to use it on a 83+ silver?

No. The 83 line doesn't have USB ports :(

Wow. this means you can have like 2 gb of games/programs.
maybe... you could have all of the programs of ti-84 archives. lol.

WOW. That's all I have to say. WOW.

Maybe a calc based mp3 player is a plausable extension to this... wait... does the 84 also have the old stereo style links?

Hey I didn't even think of that.. can you put mp3s converted by RealSound [I think that was the name of it] onto the flash drive and listen to them now?!

Yeah, this should be great for programs like RealSound which need huge files. It's sort of a pain to copy an app from the drive, play it, then delete it when done, but a frontend or something should be able to take care of that. An on-calc MP3 player wouldn't be possible, though, since they take too much processing power to decode. WAVs, maybe...

The problem is RealSound uses just about all of the 15Mhz available to it for playing the sound. There isn't much time in there for reading USB data. I do recall jim e saying he found a way to make it a whole lot faster though, so it might be possible, difficult, but possible.

Actually, I was talking about transferring data from the drive and writing it to flash, then running it, but I guess that would be hard to code and take too long.

The problem is you can't write to flash (well, you can, but you have to be careful). Dan, or anyone else for that matter, on average, how quickly does streaming from a flash drive go?

Exactly speeds depend a number of variables like drive speed and format. Reading raw sectors seems to max out at about 120 KB/s. Reading through the filesystem about 70 KB/s. Writing to the file system anywhere from 5 KB/s to 40 KB/s depending whether the file needs to be grown, the number of sectors per cluster, and the drive speed.

When you say app do you mean the kind that runs from flash memory? I can transfer programs, sure (the software is designed to do that), but I can't transfer flash apps, which is what I need more memory for in the first place.

Yah! I mean, this thing is awesome! the only thing is that the 89T already has so much memory i'm not even sure if it would be worth it. but fot the the 84+ it's very ideal!

Well, you see it isnt the amount of memory the calculator has, but the amount of memory that programs require. Yes the 89T has more memory than the 84+, but 89 progs (games, not math programs) also require a lot more memory than 84 progs do. So ~proportionately~ they are about the same.

Memory's not the only use for USB on a calculator. If a USB driver was developed for the Titanium, we could have other pointless things, like mice (wikiti.denglend.net/stuff/mouse.avi) and maybe even a USB ethernet adaptor. Yay, internet on a calculator!

Ethernet? try WiFi! The only problem is current draw is too high though (I bet both an ethernet and wireless would use more power than the port can provide). This could be resolved though by an external power supply- all you would need are some batteries and a five volt voltage regulator.

more ppl have a TI-84 than a 89T. besides, like i just said, it wouln't be THAT much better because of the current mem of the 89T. Anyways, while ppl are reading this:
where is everyone at the games Ideas board/forum/thingie. I can barely find a comment anywhere from 2006... Maybe they should delete the old ones (<2005).

That's EXACTLY what we need. it may require a tinsy bit of organization with like mods and stuffs, but I don't know if it would be THAT hard to work out! Come on ticalc.org staff! Are you all listening? I'm not saying that ur not doing a good job now, but a forum would be really nice.

I didn't say that I would MODERATE it; just create it. I'll leave most of the moderating up to the ticalc staff. I just like making forums, that's all.

They need an RSS feed for it - "83+ Games Ideas has been updated"

That would be convenient.

Here I am. ;)

OK BTtec work on something similar with SD Cards for our wireless network. (Look at our website). It's an SD card linked to a MSP 430 from texas Instruments which will setup the network but this time the extended memory is more important. The MSP 430 will eb connected to the I/O Port. I work on an graphical browser for the extended memory (look at the board for screenshots). Another member of us writes the routines for the MSP430.
