Color Screen

Blackwolf189 · Newbie Joined: 09 Apr 2004 Posts: 30

My friend and I wanna put a gameboy advance color screen into a ti-83plus calc. Our logic is all scuzzies are the same, the screen size is the same, and the interface is the same. This means that when we put the screen in, the calculator will still run in black and white. But, when we flip a switch and plug in the gameboy advance, the screen will run in color to play the gameboy advance game. is this feasible? Also this would require us finding some hardware part that has 2 scuzzies pluged into it and can switch between the two at any point in time with the push of a button.

That's pretty much impossible, but sounds cool when you say it. The GBA has way more pixels than a calc, giving it much better detail. How would you connect it?? Chances are it wouldnt do anything. Or it might give you a bunch of binary in the form of random static in a a random color, since I doubt black is the same value as it is on the calc. You could build or program some sort of an adapter to make 1 pixel show up as 4 or even 9 pixels in a square on the GBA screen, and make the on pixels black. What a waste of a GBA screen that would be.

Why is it so many people want color on graphing calculators? (Nothing against you Blackwolf.) Isn't it easier to just buy a pocket pc or something similar?

Well, you can use calculators easily in math class.

no problem man. we didnt want color on the calc we wanted to imbed a gameboy advance into the calculator and have it share 1 screen.

lets put it this way: it'll be easy to combine them if you're capable of cutting a few holes in the back of the calc. but they wouldn't share the screen

I mean the teachers won't take it away like they will a gameboy.

my teacher will
IF you use it when she is doing something else...gone for the day.
IF she using the class set to (duh) show the class something and you are pressing way to many kpm (keys per minute), poof! gone for the day...

None of my teachers would ever dream of doing that (I guess this is just a high school thing).

Every one of them know me for an EVIL calculator programmer.
At least, that's what everyone in my English and Math class thinks of me after I tried a few experiments using the link, loading EVILCODE and its installer on someone else's calc, and running the code that's in my signature.

I'm not that evil, am I?
-------------------------------------
As for the screen thing, if they were combined, would the speed of the screen be faster or slower? I mean, what kind of LCD delay would you have for something like that? Would you have to directly communicate to the darn thing, or would it be memory-mapped somehow?
-------------------------------------
Extra:
If you do decide to use and distribute the code in my sig, you may want to add:

3E14
D310

For an extra effect. I'm not sure about it, but I really don't want to test it right now.

if you where going to make the calculator use a color screen there would be three options.
1. Find the correct lcd controller and then create all new ti operating system so it would now how to talk to it. (take probably 8 years if you were working alone)
2. somehow make an extremly slow link controlled one
3. pay me half a billion bucks and I will have a research team working around the clock on making you one... while i sit in the bahamas retired at age 16 mwuhahahahahaha

4. Use half of that money to have a research team working around the clock on making you one, simultaneously sitting in the Bahamas retired at age 16.

Isn't that #3 repeated?

No, i think he meant that the first one was for the kid who orginally wanted it, and the second was for nextperception. But that is kind of dumb because once you make one, you can probably then mass produce it.

Ah, I see what he meant now. I was reading it wrong... Neutral

The simple solution I've come up with is three color backlighting. Using persitence of vision theories, it turns out the calc can produce about 16 colors without noticeable flickering (e.g. the TICI 1.0 Color Screen Adapter)

Would this work for the 83+? I mean, it can't even handle 16 shades of gray very well.
