Hello, since I upgraded my fx-9750GII SH4-A, I want to learn to use the SDK.

 

I know something about C, ANSI C, learned from my father's college book of Prentice Hall (examples are executed in DEC minis or MS-DOS, but in recent GCC it is the same)

 

I need some tutorials for learning to use the Casio fx libraries and Hitachi math libraries, I expect they are different from MS-DOS or Linux ones.

 

Do you know some good tutorial?

 

P.D.: I have less time than I would like, because I'm studying Spanish, History of Spain and History of Phylosophy to enter the college (Chemistry). I try to keep programming, but I musn't do it.

 

Thanks in advance

 

Regards

The Fx-9860gii SDK uses C by default (it also supports C++, SH4A and SH3 ASM), the SDK just uses the standard C with some extra functions for I/O and drawing. 

 

 

In the "fxlib.h" header file, there are a bunch of Bdisp functions, these functions deal with drawing pixels to the screen and clearing them.

e.g Bdisp_PutDisp_DD() is the function used to draw a pixel to the screen and Bdisp_AllClr_DD() is the function used to clear all the pixels from the screen.

 

There is a good tutorial created by Fez and reformatted by Helder7 about the Bdisp functions and basic I/O over here: http://www.casiopeia...php?f=20&t=1420

 

You can also download the official Casio docs on the fxlib library over here: http://edu.casio.com...greement.html#2

 

 

Here is a hello world program, most of this is auto-generated by the SDK when you create a new project:

As you can see from above, there is no main() function, unlike standard C our entry point to the program isn't the main() function, it is the AddIn_Main() function.

Thanks, Viliami. It seems to be relatively easy with the fxlib.h reference.

 

I want to use the math.h lib, is it the same in the hitachi c compiler than in GCC?

 

Regards

[Viliami]

I don't know if it supports all of the math.h lib functions, but it does support most of the main ones. 

 

On this page (https://edu.casio.co...load/index.html) there is a link to download the fx-9860G SDK manuals, it's a .zip file. It has a bunch of .pdfs and if you open up the "C Standard Libraries.pdf" file, you will see all of the math.h functions the SDK supports.

 

It has a math.h lib and a mathf.h lib (for floats)

 

Here is a list of the math.h functions supported by the SDK:

double acos(double d)
double asin(double d)
double atan(double d)
double atan2(double y, doublex)
double cos(double d)
double sin(double d)
double tan(double d)
double cosh(double d)
double sinh(double d)
double tanh(double d)
double exp(double d)
double frexp(double value, int *e)
double ldexp(double ret, int f)
double log(double d)
double log10(double d)
double modf(double a, double *b)
double pow(double x, double y)
double sqrt(double d)
double ceil(double d)
double fabs(double d)
double floor(double d)
double fmod(double x, double y)

Here is a list of the mathf.h functions supported by the SDK:

float acosf(float f)
float asinf(float f)
float atanf(float f)
float atan2f(float y, float x)
float cosf(float f)
float sinf(float f)
float tanf(float f)
float coshf(float f)
float sinhf(float f)
float tanhf(float f)
float expf(float f)
float frexpf(float value, int *e)
float ldexpf(float ret, int f)
float logf(float f)
float log10f(float f)
float modff(float a, float *b)
float powf(float x, float y)
float sqrtf(float f)
float ceilf(float f)
float fabsf(float f)
float floorf(float f)
float fmodf(float x, float y)

Ok, great! Thank you!

 

Yesterday I had some problems building the projects, but the problem was Windows 10 64 bits, I read old threads and reinstalled the SDK as administrator and in C:\CasioSDK folder created by me, and it worked.

 

I really appreciate your help, there are very few fx-9860G SDK active developers in 2016.

 

Also, I had problems displaying a float in the screen, is there any routine to do this, or I should with a loop, parse the float in a string?

[Viliami]

I just use the sprintf function, (which is in the stdio.h lib, also sidenote: the printXY function is from the fxlib.h lib) to convert the float into a char array and then print it to the screen.

Here is an example function:

void printFloat(int x, int y, float f){
    unsigned char buffer[9];
    sprintf(buffer, "%f", f);
    PrintXY(x,y, buffer, 0);
}

and here it is in use:

int AddIn_main(int isAppli, unsigned short OptionNum)
{
    float pi = 3.141593;            //the float we're going to print
    Bdisp_AllClr_DDVRAM();          //clear screen
    printFloat(1,1,pi);             //call the function to print the float
    Bdisp_PutDisp_DD();             //put pixels from VRAM onto the screen
    
    while(1){}
    return 1;
}
