Page 2 - TI 83+/84+ programming?

On a side note, you can overclock the CPU in TI-83 calculators!

I always used Hewlet Packard calculators with RPN... Screw order of ops! Although the last time I used a graphing calc was in 1990...

yeah, you can also replace one of the chips on the Mobo with a different one and it speeds the calculator up 4x.

hey guys, im new to the forum... and I need some help with my TI-83 Plus calculator... I am trying to make programs on my calculator for Class, but im not too experienced with this... can someone maybe post what i need to type into the program screen? I'm really quite confused. Thanks, e-mail me at Trainboy@fuse.net please i could use the help. I would like to be able to type in a radius, and plug it into the following formulas...

[r=radius]

S= 2(pi)r(squared) +2(pi)r(height) -------------- Surface Area of Cylinder
S= (pi)r(squared) + (pi)r(slant height) ---------------- Surface Area of a Cone
V= (pi)r(squared)(height) ----------------- Volume of a Cylinder
V= 1/3(pi)r(squared)(height) ------------- Volume of a Cone
S= 4(pi)r(squared) ----------------- Surface Area of Sphere
V=4/3(pi)r(cubed) ----------------- Volume of sphere

if this isnt possible, can someone atleast e-mail me and tell me of some commands or how to make programs please? if not, i would like to know how to enter these formulas...

Thanks

ok when writng a program like that you will need to use some commands. one of them is the input command it will allow you to enter a number and it will store it into a variable. another is disp which will display text so you know what is being asked for.

example:



first its asking to enter the radius and the height, then it takes those numbers and plugs them into the formula, lastly it stores the answer of the formula into the variable x and displays it.

I hope this helps.

hey thanks for trying to help me out with my formulas... i dont exactly know how the programs work yet and its really going to come in handy. I'll make another post if i need ur help again ;-)

hey guys I'm new at this so here it goes

storing text on the ti 83 is very easy and use full when programing games that involve it. here is some source:

:ClearHome
:Input "Name: ",Str1
:ClearHome
isp "Hello", Str1
:


I know this isn't a complicated program but hopefully it will show you how to store text Values

Also Str1-9 is found under the VARS key all the way at the bottom.

Well I've learned more about the programming features and I've become quite skilled at it. I am working on a game right now for the TI-84 Plus SE and I was wondering if anyone would like to help. I don't have many details but this is the only thing I have yet to do so I'm going to give it a shot.

And I kind of need help making my game use the graph commands like drawing and shading and stuff like that. If anyone would like to help it would be greatly appreciated.

Anyone! I Am new to TI 83 programming. I am having a problem with finding a space key on the TI 83 plus keypad. Is there a space Key??? I have an old HP48sx which I use often and it has a space key. I was assuming that the TI83 plus would too but I can't find one. I am asking because sometimes I try to program with my calculator while I am traveling. I know I can use a space when I'm typing with the TI connect program but is there one on the calculator. This has been bugging me. Also I notice that all program code that is displayed on the websites have spaces in there programs.

PLEASE HELP...ITS KILLING ME!

Thanks very much.

Its is the 0 key in alpha.

Merged TI-83 threads... considering how popular the -83 is, I may just sticky this one.

Im currently developing a turn based rpg game with easily usable custom menus and some cool graphics for the attacks. While i was framing out the programming, I was wondering a few things:

1: How should you enter battle.
-A map that contains room #s and is usable from the home screen and uses the arrow keys to move from room to room?
-An "action" or something screen with a main door and some shops located along the side of the room and other stuff?
-I've made other rpg games and the simple BATTLE! option gets a bit boring

2: This is a opinion question. Items and gear. Would it be cooler to get money drops from enemies and randomly find scrolls that give power ups ( stat uppers ) before battle? orrr...
- Get gear drops from enemies including weapons and armor pieces?


o also anyone got any really good formulas for increasing required exp for the next level?
ex. iPart((exp required currently) * .25)=10??? or something like that?

thanks

83 progs should work for the 84. try googling it and find the TIconnect program. Works like a charm for me on my 83+.

And damn...why didn't I find this thread before? I've been programming on my 83 since freshman year (4 years). all programs that do basica math functions areinherently the same. You take a number of inputs, stick them in an equation, and get an output stored to a variable. Then display this variable. I made my programs complex to the point of putting the input in the middle of the screen, then clearing and prompting with a clear screen for each one, fake calculating/loading screen (or that may have been in qbasic), and output with a pause, and back to a huge menu. I think, when I had them all done, I had about 15 programs. Calculating everything from slopw of a line ro distance between points given two points, to circle/cone/cylinder stuff. Just do what I did and mess around, playing with functions. If you see something new, try it. It's just about impossible to damage the calculator with the functions in it already. Try it, see how it works, then use it in your program. Or......try THIS program:

(cause I don't know how to do the code tag)

Code:

:
clrhome
clrdraw
axesoff
lbl 1
randint(0,55)->A
randint(0,75)->B
text(A, B, "STUFF")
goto 1

/code

- also played with making a kill switch, and did it well...but forgot the code to do it (hit on to terminate any program, like ctrl+c in dos.

lol distance

uhhhh the calc came with a book on how to program it.

Hello,

I'm in need a the code for a program to help solve system of equations problems. I'm sick of this substitution and elimination stuff, but I mainly need the program to check.

Please post code, and if there are any weird buttons please show how to get to them, I know most of them though.

Thanks!

This thread gets enough traffic, one way or another, to warrant sticking, so now it is.

One can find the manual for the TI-83 here.
