Hey, I'd like someone to tell me how can you produce real sound in a TI-89. I suppose it's related with ASM programming... (Be serious please).

Im not sure how to program it but I know if you get a 3.5mm to 2.5 mm converter and plug it and your headphones into they link port its possible to get sound. Im not sure how many programs have it but it involves sending voltages at the right frequency for the headphones to work.

I need to know what type of resistor to use to hook up POWER SPEAKERS.

GOt any Ideas?

yo, i have a program for 83+ that i believe was ported from 89 that gives it sound. for it to work either buy the necessary equipment from the TI people, make your own speaker or hold it up to the speakers of a radio that is tuned to an unused AM radio station. I found it by following a chain of links starting at www.tigalaxy.com, but unfornately i don't remember which links. it works okay, but it's not the same as the original for the 89 (before it was ported)

Sound

Sound is quite simple to produce via - you guessed it - ASM.
You do this by pulsing the link-port high and low. In TI-83+ asm you set the pins high with:

ld a,d0hd1h
out (BPORT),a

and low with

ld a,d0ld1l
out (BPORT),a

FM (Frequency Modulation) can be achieved with this sort of thing:

1: Make link port High
2: Pause for 'PITCH'
3: Make link port Low
4: Pause for 'PITCH'
5: Decrease 'DURATION', if it isn't 0 GOTO 1

You specify PITCH (the higher the value, the lower the pitch) and DURATION.

I've written some routines for playing WAV files out of the link port (in stereo) - click the WEB PAGE link for a demo!

Re: Sound

It is (with clever thinking) possible to create sound through BASIC. because sound is just bytes interpreted by the headphones. I don't program in BASIC as I think it is hiddiously slow, but it is possible through a modified TI-OS (only needs slight modification (like a couple bytes)). I know it's annoying that i keep proving a lot of people wrong but you know how that goes.

Someone should make a game with music/sound effects for the 83+ (sort of like Duke68k for the 89). Mario like that would be cool, as would Pheonix. If that's possible, someone please make something like that.

Yeah...
Is it possible to change only some of the pixels to blue annd leave the rest at black? Also, I've seen some pretty good 4-level greyscale programs for the 83+; Pheonix, Zelda, Mario, Breakout all would be good games with sound/color. Someone make games like that if possible! Oh, and you can get some pretty big Apps (64K, Geomaster). Someone should make a HUGE game as an App with sound/color!!!!

If some1 does figure that out I will promise to make a Sonic game where sonic is blue and background is black/white/gray

Goto the Graphics ideas section, they have a LOT on color there...

(P.S. That program that draws the triangles in the 83+ handbook? That burned itself into my friend's screen...)

Oh, also, a good App of that type could win the App Contest!!! Everyone start making cool games!!!

Another good game to make would be Brave Fencer Musashi (for Playstation). That or any other behind the character 3D game would be very cool on a calc.

I;m working on a new BASIC gane engine, using ZAPI, o it could be as fast as ASM if I get the code right. I'm thinking of doing a lookdown version of Lord of the Rings (I already have a playble demo, but then I might make it second-peron, ehind the head. I might do HALO this way as well.

Hey. there is also a way to change the LCD driver controls and have it use color (this of course would require direct machine code directly into the driver)! and as for sound, I have been frustrated at the amount of ram given for use on the 83 plus but I am curently in consrtuction of a "ram pack" that would hook in to the link port and would contain extra (we're talkin megs) ram. I've also tried to figure out a way to add another link port and a speaker to my creation. when I'm done I'll let you people know. if anyone want to know how to do any of the things i've talked about reply and i'll post it.

Ram pack
nishant srivastava  Account Info

awesome! i could use this so much as ihave a normal ti 83+ and need space for prgms. when do u plan on finishing it? you should sell it!but please give me a free one! also, offtopic,(most) people w/ silvers are pansys and only use em to show off. my friend has a silver with mirage and phoenix on it. i have 75-80 prgms on my black edition.all over 500bytes,some arch-ed and 12 apps!

Damn! You replied kinda late! Ahem!

I recently gave up z80 programming as it didn't interest me anymore, but the number of replies and emails I'm getting has inspired me to finish my construction.

Thanks guys! Without you I'd never do z80 again!

I have been a little depressed lately cuz of Hannah. She always piss'n me off, but I still love her. That's why I haven't been able to finish my project. I think I'm ok now.

COLORS?

COLORS?
How can a black/white screen make colors? Ever seen a black/white TV making colors, yes if you paint the screen it is posible.

A black/white screen NEVER will output colors.
Most calculators can output grayscale by changing the pixels black-white-black-white rather quick.

(If your black/white calculator has colors please tell me)

This has nothing to do with sound, but by overloading the LCD you can make parts of the screen look blue.

It is almost impossible to control, only affects whole rows and may damage your LCD...

COLORS.... yes... I have had my ti-83+ make colors. I've done it many times too. Not by BASIC... Not by ASM... by typing in a seris of commands that like "Crash the OS" Not literly. It is quiet interesting. But it is not supposed to be good for the lcd. Blue is only color that i've got. but hey it fun "Crashing the OS". Teacher almost killed me the first time it did it though.

Re: COLORS?

No offense, but you are hiddiously wrong. I work as a programmer at BAH and i specialize in extending the possibilities of machines. If you change the controls of a driver it perform anything you want. the problem is that too many colors added to the insrtuction set will make it run a slight bit slower. and just in case you were wondering I am 13 (i said this because most people think that if you're a programmer then you're an adult).

And another thing:
A black and white TV CAN MAKE COLORS!
All you must do is add a light-spectral prism to the edge of the screen and voila! The screen emits the light spectral eqivalent of the shade of white or gray the TV is using.

Ugh...You idiots...You don't know how to do color?!!

1.) Get a TI-84+(SE).
2.) Install xLib on it.
3.) Run the following program:

:ClrHome
:Repeat getKey
:real(5,39
:real(5,0
:End

I don't think that is a good idea. I tried it and it wore my screen out. Took a while to get my calc to turn on again!
