Hi,

Am trying to develop a mathematical program to calculate time when speed and distance are given.

How can I get user input ie, the distance and speed.

And then to calculate and display the results.

Please help.

First of all, you will need revolutionFX. Secondly, you will need to put this at the top of your C program:

#include "fxlib.h"
#include "revolution.h"

fxlib.h and revolution.h should be in the same folder as your C program.


About the string input:

I got some information from this page


Prototype:

int string_input(int x, int y, char string[]);

Now, what you need to do is find out if the Casio SDK has atoi or an alternative. You are going to need to convert the string to ascii.

Your code will probably look like this:

//include the revolutionFX libs
#include "fxlib.h"
#include "revolution.h"

//Prototype the string_input function
int string_input(int x, int y, char string[]);

//Declare variables
char string_[];
int A;
int B;
int ans;


//main program
int main () {
   Bdisp_AllClr_VRAM();
   PrintXY (1, 1, "A:");						   //That's PrizmSDK code... I don't know what Casio FX SDK has.
   Bdisp_PutDisp_DD();
   string_input (4, 1, &string_);
   atoi (A, string);


   Bdisp_AllClr_VRAM();
   PrintXY (1, 1, "B:");
   Bdisp_PutDisp_DD();
   string_input (4, 1, &string_);
   atoi (B, string);
   

   Bdisp_AllClr_VRAM();   
   ans = a + b;
   PrintXY (1,1,ans);
   Bdisp_PutDisp_DD();
   //end program
   return 0
}

I did not test that code, but it should give you an idea.

What model are you developing for? The instructions may vary, depending on the model, and your host OS.

He's using the fx-9860GII.

Hi there,
Is there any ready made C routine for casio SDK can be used to evaluate a formula in the string format, such as: (S^2+3)/((S^+1)*(S^2+10))?

Or is there any way to call the calculator's fn function?

Please help

I think revolutionfx can handle that, but i'm not entirely sure.

I think revolutionfx can handle that, but i'm not entirely sure.

i've been trying to use the revolutionfx library with the SDK for so long without success.

 

Do you have a Step by Step Tutorial about Setting Up the SDK for this library?

 

Thanks
