Casio Basic to SDK

[SimonLothar]

is there a plot function in the sdk or do i have to write an own one?

There are syscalls 0x2F to 0x33 which do various plot-functions.

i looked up those 2 syscalls in your syscall pdf file. if i understand it correct, 0x2F is a variable and the other one will be the plot command. I put it in the following code.

Code: Select all

    Bdisp_AllClr_DDVRAM();


PLOTX(5*VARX());
    while(1){
        GetKey(&key);
    }

    return 1;
}


My questions are:
(1) is the syscall done correctly? i assumed that the variable doesnt need to have input, correct me if im wrong.
(2) what still needs to be added to make it work

thanks in advance

You need some code like

Code: Select all

typedef struct{
    unsigned int x1;
    unsigned int y1;
    unsigned int x2;
    unsigned int y2;
    unsigned char f[4];
    unsigned int on_bits;
    unsigned int off_bits;
} TShapeX;

typedef int(*sc_itshp)(TShapeX*);

const unsigned int sc0x2F[] = { SCA, SCB, SCE, 0x2F };
#define Bdisp_ShapeToVRAM (*(sc_itshp)sc0x2F)

const unsigned int sc0x33[] = { SCA, SCB, SCE, 0x33 };
#define Bdisp_ShapeToVRAM_DD (*(sc_itshp)sc0x33)

//
int F00_1_Handler(){
TShapeX shape;
unsigned int key;
   Bdisp_AllClr_VRAM();

   shape.x1 = 10;
   shape.y1 = 15;
   shape.x2 = 20;
   shape.y2 = 25;
   shape.f[0] = 2;
   shape.f[1] = 2;
   shape.f[2] = 1;
   shape.f[3] = 1;
   shape.on_bits = 3;
   shape.off_bits = 3;

    Bdisp_ShapeToVRAM( &shape );
   
   GetKey( &key );

   return 1;
}


The members of TShape are documented in my CHM-Helpfile http://www.casiopeia.net/forum/downloads.php?view=detail&df_id=72.

ah i think you misunderstood the question. what i understand from the help file is that these syscalls draw shapes on the desired location. But what i wanted to do was to plot a real function.
as in the graph menu. would that be possible?

i have 2 more other questions.
1) how do i ask for a numerical input to store in a variable?
2) how do i make a nice scrolling screen or menu where most of the menu or scren does not fit on the screen and by moving with the cursors the focus moves along.

I don't know yet, whether the graph-menu-plot-operations are sufficiently encapsulated to be used from out of an addin (t. i. as syscall or combination of syscalls). I'll have a look.
