Total Posts: 199 | Hey everyone. I've just made a calculator heaphone adapter, and already have started working with sound. I was planning to do an IR link, but that will have to wait. (cost, equipment, time...) But this sound thing is coming out good. Check this out:
http://www.angelfire.com/amiga2/anthonyl/archives/SoundBst.asm
That routine plays a pure tone on the TI-86, given a wavelength and duration. I'm gonna post a picture of an oscilliscope image to show how a TI-calculator sound looks like in its wave form. It's actually quite interesting. Expect the picture in about five or six hours, at least. |

Total Posts: 199 | Nope. Plus, I use rechargeables :blink_a:. It depends what you use as headphones. If you use big ones, the battery drops quicker. If you use earphones, there is no change. The oscilliscope is just a probe; doesnt hurt the calc any way.
[EDIT] I guess that oscilliscope image might be a little later. Those things are tricky to use!

Actually, if you tell me what the "ConcOP1" ROM call does, i can port the rest. That is, if you don't mind.

http://www.angelfire.com/amiga2/anthonyl/archives
The pictures are shots of an oscilloscope hooked up to my TI-86 running a program using my sound routine. The first one is a medium frequency, while the second is the highest one attainable on the TI, which is 46.5 kHz. You can see a bit of overlapping on the second one, but the sound is quite pure.

Total Posts: 199 | I could post a pic of the adapter, but I don't have my camera with me at the moment. However, I basically did this:
1.) I found a broken personal radio in my house
2.) I opened the radio, and unsoldered the jack
3.) After cutting a small TI cable in half (I have a bunch) I stripped the wire about half an inch. Then, I gathered all the copper wires inside and twisted them together. (There were two wires, and a copper shield around them; it consisted of a ton of small copper wires)
4.) Then I identified where each wire connected to (the jack has a tip, a middle, and a base). I did the same for the headphone jack.
5.) I soldered each corresponding wire to the contact panels on the headphone jack. Then, I wrapped the whole thing in alot of electric tape.
In the end, I have a 2-3 inch stub, with a headphone-in jack on one end, and a calc-out jack on the other. |

I see the copper wires, the red wire, and the white wire on the TI cable btw, but i'm having trouble separating the speaker face from the body so that i can jack the jack |

Total Posts: 2007 | It works on my regular 83+, or so it seems. I can't hear sound cause I haven't finished that part yet, but the program runs fine and shows no errors. I made it run under Mirage as well and gave it a nifty little image of soundwaves echoing outward from the centerpoint. I also can't use VTI cause i have a silver link cable and i'm too lazy to get a rom dump any other way btw. |

Total Posts: 199 | As suggested by TI Freak, I think you could probably buy one. If you can't then do the following:
If you just have a pair of headphones, and a cut TI link, just connect the wires. Cut the plug off the headphones, and splice it. Then, connect the wires. If the copper wire doesn't exist in the headphones, then tape the one from the TI link out of the way. Then connect the two TI wires to the two headphone wires, and your done! I hope that helps. |

Total Posts: 199 | That could be your problem; Speakers require a lot of power; Unless their smaller than 1 inch in diameter, you might not hear much.
Although, I hooked a 1ft subwoofer and two 6inch speakers to my calc, and played mario, and it worked fine. I pumped the volume up real high.
But then again, they get power from the AC wall plug...

Total Posts: 2007 | I got my speakers hooked up finally and the sound works perfectly! right now all it does is beep, but at least it makes sound. I will have the program and source (83/84+/SE version) on my site, HERE
EDIT: Working on making it put out the Mario theme song :) :) . Just takes a lotta time to get the frequencies and durations right tho. I also added a pause routine that has the same d-input as the soundblast one, but puts out no sound. Very useful for little breaks in the sound. One bug I found, however, is if you set a to 255, it plays for about 3 times as long as it normally should, and if it's at 250-254, it plays for hardly any time at all.

Total Posts: 199 | Yup! That bug exists; I used to have that as a comment, but I must have deleted it. For some reason that happens, 254 works, and 255 plays, but then it holds the tune for a while. Another thing about this routine is that it can only hit high frequency's. Low ones require a tweaked routine, but it's not a big deal.
Good job getting it to work; and good luck with the Mario theme song! I can work on my routine so it accepts a series of values rather than one at a time.
[EDIT] Nice source code! However, the comments are out of date a bit. Did you notice that when I changed the code before, I changed the 254 loop counter? The routine's code is the same as mine, but the comments are from the old version. However, nice job! I wish I had an emulator to see how it really sounds. I assume, since the processor is faster than the 86, that the routine outputs higher frequency. Pretty interesting...

And I've kinda abandonned that project to my low priority list, so until i finish my shell and my sprite program, or maybe sometime when I have alot of free time, I'll get back to it. Also, Greenorange, I think I will tweak it to use hl for the frequency instead of a. One question though, do I output both h and l at the same time, or do i put a pause in between? |

Total Posts: 199 | My assembly might be bad off the top of my head, but I think you can use either h or l rather than both. If you send it a number (which should be less than 255) it will only go to l. That way, only output l, unless it cannot hold the value. Then I think you should not use any pauses, or the frequency will be invalid. |

plug the 2.5 into ur linkport and headphones into the 3.5.
84+ users will need to shave of quit a bit of the plastic casing to get it to fit into the sunken linkport.
i also used this adapter to hook up a usb->audio cable for my wireless chat progs :-D
