is the part with the syscall correct? cause i dont really understand that part

That's one of my oldies. Nowadays I'd rather use this

Code: Select all

// instant syscalls (fx-9860)
#define SCA 0xD201D002
#define SCB 0x422B0009
#define SCE 0x80010070
typedef int(*sc_iv)(void);

const unsigned int iGetVRAMPtr[] = { SCA, SCB, SCE, 0x0135 };
//
int GetVRAMPtr( void ){
    return (*(sc_iv)iGetVRAMPtr)();
}


Syscalls are compiled C-functions inside of the OS. You need the interface only.
Advantages:
it is not necessary to write the code yourself; the code does not load your G1A-size; the code is well checked.

SCA, SCB, SCE represent the MPU-instructions to call a syscall on a fx-9860.

woohooo, simon you are the best! It is working now

i want to clear an area of the DD. My syntax is

Code: Select all

Bdisp_AreaClr_DD(0,0,50,50);


but it doesnt seem to be right.
Bdisp_AreaReverseVRAM(0,0,50,50); does work.
so the parameters inside are wrong?

Try this code:

Code: Select all

DISPBOX clear_area;

clear_area.left = 0;
clear_area.top = 0;
clear_area.right = 50;
clear_area.bottom = 50;

Bdisp_AreaClr_DD(&clear_area);

I had the same error, but comment this lines, compile, and decomment. Next, compile, this error will quit

Sorry for my bad English...

ok the dispbox works, but on the left side there is something strange.
this is the code i use

Code: Select all

int AddIn_main(int isAppli, unsigned short OptionNum)
{
    unsigned int key;
DISPBOX clear_area;
Bdisp_AllClr_DDVRAM();
Bdisp_AreaReverseVRAM(0,0,127,63);
clear_area.left = 0;
clear_area.top = 0;
clear_area.right = 127;
clear_area.bottom = 63;

Bdisp_PutDispArea_DD(&clear_area);

    while(1){
    }

    return 1;
}


as getkey puts the whole screen i left it out.

here is the pic of what the result is

so what might be the problem?

[SimonLothar]

I used the original SDK and my mini-SDK and observed exactly the same erroneous result in both environments.

Looks like there is some bug in Bdisp_PutDispArea_DD().
I'd rather avoid this function for the time being.

So relax. Seems to be not your fault.

If you want to clear an area you could use Bdisp_AreaClr_DD() as well.
If you want to draw a certain bitmap you could use Bdisp_WriteGraph_DD().

As I said before, you should really use MonochromeLib by Pierrotll, which provides lots of useful graphics functions.

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