Guide to Programming Your Calculator

Hi everyone one, i just recently finished school and i don't think i would have been able to make it through school without programming my calculator, so here it is:

What You Need:
Ti-81 or higher [I will be using a Ti-84+ SE]
Basic Math Knowledge
Time

Table of Contents:

• Basics
• Basic Commands
• Using the Program
• Other Commands
• Creating Advanced Programs

Basics:
To make a program you must be able to get the the proper interface:
Press the program button [PRGM]
Go over to the "NEW" tab by pressing the arrows
Press enter once it says "1:Create New"
Now just name your program

You will see something like this:

Code:

PROGRAM:TEST
:

Now, what ever it says after "PROGRAM:" is the name of your program, you can't change this.

<Basic Commands>
You have your normal [+ -, /, *] signs but to program your calculator you will need more that

Will start of simple, we will make a program that will give you the sum of 3 numbers.

Code:

PROGRAM:TEST
:Input A
:Input B
:Input C
:(A+B+C)->D
:Disp D

Lets break down this script, you have your 3 Inputs A,B,C these will be your variables, then you have the math (A+B+C) then you have it showing you the answer [D]

Input:Varibles for #'s
->:Store answer as another #
Disp: Displays whatever is following it

You can get the input and Disp by pressing the PRGM button again once you at the

Code:

PROMGRAM:TEST
:

screen.

You will see alot of different things pop up, but you want to go to I/O [input and output] the first one on this list is input, simply press ENTER to have it placed in your code, something like this will show up:

Code:

PROGRAM:TEST
:Input 

After input you need to have a letter, so press the green ALPHA button then press any letter [They are above most of the keys in green] You should have something like this:

Code:

PROGRAM:TEST
:Input A

Input automatically creates a variable for the letter.

Now, -> , this is a simple command after any operation that you would like to store the answer for you would press the STO> button, its right above ON, after the -> you want to put another letter so press the green ALPHA button again and you should get this:

Code:

PROGRAM:TEST
:(A+B+C)->D 

Lastly in this code it the DISP, this is a very simple command it just displays whatever comes after it which is D, so it will show the # D

Code:

PROGRAM:TEST
:Disp D

<Using The Program>

so if you were to start this program you would press the PRGM button, go down to TEST and hit enter, you would get something like this:

Code:

 prgrmTEST 

When you see that hit enter again and you should get something like this:

Code:

 prgmTEST
?

For the first ? enter you first number

Code:

 prgmTEST
?1

Then press enter. You would get something like this:

Code:

 prgmTEST
?1
?

Enter you second number and press enter, you will get this:

Code:

 prgmTEST
?1
?3
?

And lastly enter your third number and press enter, you will get something like this:

Code:

 prgmTEST
?1
?3
?2

                           6
                        Done

And that is how you would work this basic program.

The Menu
Now say i wanted to put more than one function into a single program, i would make a menu of all the different functions.

When you try to use a menu you will also need to know about labels and some other commands.

Menu:Basis for interface
Label:Labeling of each different function

It isn't too hard to incorporate a menu into your programs, you will have to start off the same way as the first program.

Once you get the the main programming screen go to PRGM and stay on the first tab "CTL". scroll down untill you come to Menu(

MORE TO COME LATER ON [im leaving atm but should be back soon]

 

i dont understand which caluclator this is for.. and pics would be nice as well.. explain please for those who do not know.

 

Yes, you gave no explanation of how we benefit from reading and doing this.

 

It's for graphing calculators, like Ti-84. You can program games on it.
