adding memory to your ti-84

the doctor (guest) 20 Jan 2014 17:06

I've finally figured out to play music using trusound, but the problem is that the songs take up sooo much space on the calculator. For example a 42 second portion of the song Radioactive takes up 835584. My remaining archeiveable space is 134805. I've already deleted quite a lot of apps from my calculator to fit just this song on it. Is it at all possible to put some sort of card or baby flash drive into the calculator? Or even a better way to compress the songs? I don't mind much if the quality isn't the best, I just need to have more space.

You can check out usb8x, but it might not work on some calculators due to undocumented changes in hardware (specifically, for a little while, the calcs came with 6 additional RAM pages for a total of 128KB of RAM, 8 of which the OS uses, now they have 3 pages, but the CSE has 8 again).

As for compression, the difficulty with that is decompressing. 3.5 inch floppy discs have more memory than the calculator and they worked on processors over a hundred times faster.

MIDI files are much better suited for the low-memory environment, and for that, there is QuadPlayer as a good example.

Just ordered an adapter for headphones, let's see if a TI-84 Plus can compete with an iPod :D

HELP ME, my calculator is messed up!
Now, when I press a key I need to hold it for about a second until it is being evaluated by the OS.
This problem occurs everywhere except in MirageOS. I launched this app, listened to sample music and then when I quitted the program I couldn't turn the calc off (It seems like every button except ON works).

Nevermind, I archived every program and then reset the RAM and after that everything works fine again

Hmm, which app? It seems to me that it isn't writing a 0 to the link port, so the calculator is trying to establish a non-existent link. MirageOS works smoothly because it sets up custom interrupts, so it disables the link port from being able to trigger them.

If you are able to, the following program should fix the problem:

It's annoying that you would have to do that manually :/

EDIT: Also, if you have headphones in, it will do that, too. The fix for that is just to unplug headphones while the OS is active.

Thanks. Does this mean that the headphones need to be plugged in until one quits MirageOS?

Quadplayer is the app I used as you recommended

Hmm, that's odd that Quadplayer wouldn't reset the link port. I don't think it should matter when you unplug the headphones though.

Wait, the TI-84+CE has speakers?!?

The OP is using an 84 Plus, which is able to play sound through the link port on the top. This port was removed for the CE, however, so as of now there is no way to play sound without using an external method (which has been done- see cemete_ch/t13819, replace the underscore with ".") or using the (still under development) USB libraries, which has not been done.
