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

I am now asking for ideas. Can you give me some ideas for the App Contest. Whoever's idea I take will see it come to life (I promise). Thank you!

Make a greyscale raycasting PUZZLE (for the educational value) game with sound.

Make an app that nukes other peoples calc's memory. All my teachers have one, but i dont know where they got them.

Or make an app that emulates another programming language. there are a few out already.

BETTER IDEA

Make an app that allows you to program C/hex/asm on calc.

Today I wrote my first program!!! Woo Who!!!

It will caclualte pH from Ka/Kb and Ci, but I need help taking it to the next level. Sometimes in pH calculations a second ionization is required.

So I would like to have the program ask if I want to proceed with a 2nd inoization. I respond to the Q, ie 1 yes, 2 for no... If I hit yes the program would cont. No the program would end.

Any suggestions???? I read the manual and I did not seem to find any info on this. Also, I know nothing about programing, I'm just a Chem major with too much spare time.

Thanks in advance for any help!!

I am guessing that your program looks somthing like this:

1st part of equasion

Ask for second part, if no goto end

2nd part of equasion

(end)

I had this same problem with some programs I made at first, and I found that I could solve this problem by at the end of the program, using the I/O command DISP, then I typed 2nd, (-) key, which brought up the command ANS. So, I told the program to DISP ANS, or display the answer. Of course, I only have a TI-83 Plus, and if you have a higher or lower version, this may not help.

HEY MR. ASSEMBLY PROGRAMMER & EVERYONE ELSE:
HERE'S THE BEST IDEA; somebody better freaking DO this;
there is NO REASON NOT TO (I will get a freaking
petition if I have to get some body to do this):

check out the minitune (play cminor3) & calcmod
(play something with stereo sound) for the ti83+
and you'll see how it is capable of decent sound;
(there are even programs that will play .wav files,
but they take up too much memory)

THE POINT ---> .
why the hell hasn't anybody made any assembly games
with SOUND yet!? It's a great idea; even if if they
just make stupid beeps like atari games! Even some of
the old Nintendo (NES) games have "music" composed of
different pitches of beeps & stuff. C'MON, even some
versions of PONG beep (I think)!

Are you good at BASIC? Because you can make even Basic programs with sound. Use sndlib, which you can download here. You store numbers in two variables to set the pitch and length of the note to be played, the Asm(prgmSND. It's that simple. I might remake some good Basic games that way.

I have used SNDLIB several times, all of which
attempts it NEVER WORKED!
-Why? does anyone else have this problem?????????

Ooh!, ooh!, I have!

-Sndlib SUCKS!, the only time it works is when you
execute the included example (sound) program! >:(P

I'm sure this has been mentioned before and shot down. But I thought I'd bring it up anyway for purposes of theory. And actually, it may be possible to play short and/or low-quality MP3s.

The obvious problems - the killers by themselves - are memory and CPU speed. Only the 83+SE has enough memory to store a song of any good length. But there's no way anything short of a 68K can muster the CPU speed to decode an MP3 - and I'm not even sure that can. But about 1.5 minutes of low-quality (but still enjoyable) music could be stuffed into an 89 or 92+'s flash. And if a basic 68K isn't fast enough, it can be overclocked (somewhat).

For academic purposes, let's ignore those. The next problem is playing anything besides square waves. You'll need a DAC or two, and some circuitry (or better yet, a microcontroller) to assemble raw bits coming over the link into bytes/words to send to the DAC.

*Over the link*. This seems like the second killer. I don't know what bandwidth is possible from a (possibly overclocked) 89/92+, one-way, no-error-checking, ultra-simplified protocol (possibly 2 bits at a time, with Manchester encoding for timing.) I do know you can get decent mono sound at 22.5kbps. So if this is achievable, then it's irrelevant. If not, and you want enjoyable quality, you'll need compression - something simple, like Huffman or LZ77, that won't overload the microcontroller or what's left of the calc CPU.

Moral: It may be possible to store and play a small amount of mediocre music on your 89/92+.

BTW, cellphone headsets make good mono headphones - right plug size and all. It may also be possible to use them for sound input.

Oops. Actually, it's not 22.5 kilobits per second, it's 22500 bytes per second. BIG difference.

Ogg Vorbis would probably be better than MP3 for this. And even if proper wave sound can't be done, MIDIs and game music would sound a lot better.

I don't know much about the bus architecture, but presumably with some hardware modification it could be directly tapped into. Then, a sound card could either read calculator memory or map in some of its own memory for much faster access. If the second, then it could also have some extra flash for storing MP3s!

The only way to ever possibly to get mp3's pn the calc is to completly rewrite the os to do nothing but play sound.But this takes out the convience and you might as well just buy an mp3 player(you cheap bastards).As for games a MIDI or wav style sound would be appropriate for things such as SFX(gunshots,explosions,etc.),Bkgnd music would take a pretty complex system of multitasking and should be saved for the higher end 68k calcs.

This is the BEST idea; anybody can do this (it is MUCH easier than it sounds in many aspects, and there are SO MANY WAYS you can do this, and SO MANY THINGS you can add)

THE POINT:
The idea is to make a PROGRAM that will read "BASIC" from a source file and convert into Assembly commands in a .z80 file (Tasm can compile it into a .8xp or something). The cool thing is that, since it's your program (or "our's", if anybody thinks we should get a bunch of people to help with how it will work), the code does not have to be in the EXACT format as on the calc; it can be however you want.

You could Also add extra features/commands that coudn't be done in z80 BASIC, but that could be done in ASM. However it's done (however simple), it can be in any format. It could be like a new programming languege or something that is nearly the same as (or better than) BASIC

It could start with the easy stuff like Disp, ClrHome, Input for Vars, Rom Calls, etc... and could have more complicated stuff added later. If anyone wants to take the idae far enough, then maybe I could see an actual Compiler thingy.

To some point I have done this however, It lacks many things but tries to make source understandable to a BASIC programmer. For the most part it has been sucessful. It still lacks many IMPORTANT things, such as: Floating point numbers, complex conditionals and syntax checking(computer-based) as well as a few miscellanious things here and there that I can't tink of right now.If you want to look into this plz email or im me

Since it bothers me that people can just not know
stuff that I know, because I have nothing better to
do, and because I like to teach people stuff...

ALL YOU BASIC PROGRAMMERS SUCK! no offense, I am also
a basic programmer...but I see so many programs that
could be done MUCH better (haven't seen ONE that I
couldn't improve)

So, if you want I can teach you basic programmers how
to program WELL and/or VERY Efficiently! I know some
of you think you know all the "tricks" and stuff...
but even people who think they can do all this stuff
well enough can learn plenty from me as far as Basic
programming; I can do things that shouldn't be done
in Basic

Hello? Pay attention to me! I'm so Bored!!!

Really. And I don't suppose you've seen any of the Final Fantasy games by Maxcoderz. You should look at them. And download them. And play them. And TRY to improve them.

(Unfortunately, all of my really cool games are works in progress, so I have to defend other games)

drop me an email if you'd want to teach a n00b some stuff... basic at first, i just got my first calc 2 weeks ago and only created a few programs that display my formulas for physics and some math progs for finding distance, slope, all that good stuff.

[w00xy@charter.net]

just find some programs, run them, and then take them apart. That's what I did. Try to figure out what parts of the program did what, and then write little test programs to see if your right. download any program that you are unfamilliar with, even if it seems pretty pointless at the time.

And by the way, there's nothing wrong with BASIC. In my oppinion, it's probably the best simply because no matter how bad you screw up your programs, it can be fixed (unlike assembly where if you screw up bad enough your cal becomes useless) most of the crappy progs out there are made by ppl who never actually bothered to learn the WHOLE language

Please teach me!!!!! I am new to the programming world and id like to make something cool on my calculator.
Contact me on marina_moroz@lycos.com

I'd like to learn a few things. I'm fairly good but no where near really good. I know a few triks like leevin off final paren and quotes and stuff but nothin really good. email me plz. it would be greatly appreciated. NO SPAM!
