danzeff osk and graphics.h library problem

[ne0h]

Excuse me,
I'm working on a text editor,
I've already write all the functions, but now I'll add the danzeff osk!
I've writed this:

Code: Select all

while (1)
{
        psp_main_screen();
        
        if (danzeff)
        {
            guStart();
            danzeff_render();
        }
        
        flipScreen();

      ....
}

( initGraphics(); is called before, and the main_screen blit 2 images to screen using blitAlphaImageToScreen function )
But It doesn't work,
when I press SELECT ( to active the osk ) the psp freeze, why?
Sorry for my bad english!

[ne0h]

I've try with this solution:

Code: Select all

while (1)
{
        psp_main_screen();
       
        if (danzeff)
        {
            guStart();
            danzeff_render();
            sceGuFinish();
            sceGuSync(0,0);
        }
       
        flipScreen();

      ....
}

But this is the results:

And this is the screen before try to blit the osk:


Please, help! :(

The init code used in graphics.c doesn't work for things like intraFonts or danzeff. Try this one:

Code: Select all

	// setup GU
	sceGuInit();
	sceGuStart(GU_DIRECT,list);
	sceGuDrawBuffer(GU_PSM_8888,(void*)DRAW_BUF,BUF_WIDTH);
	sceGuDispBuffer(SCR_WIDTH,SCR_HEIGHT,(void*)DISP_BUF,BUF_WIDTH);
	sceGuDepthBuffer((void*)DEBUG_BUF,BUF_WIDTH);
	sceGuOffset(2048 - (SCR_WIDTH/2),2048 - (SCR_HEIGHT/2));
	sceGuViewport(2048,2048,SCR_WIDTH,SCR_HEIGHT);
	sceGuDepthRange(65535,0);
	sceGuDepthMask(GU_TRUE);
	sceGuDisable(GU_DEPTH_TEST);
	sceGuDisable(GU_BLEND);
	sceGuScissor(0,0,SCR_WIDTH,SCR_HEIGHT);
	sceGuEnable(GU_SCISSOR_TEST);
	sceGuFrontFace(GU_CW);
	sceGuEnable(GU_TEXTURE_2D);
	sceGuClear(GU_COLOR_BUFFER_BIT);
	sceGuFinish();
	sceGuSync(0,0);
	sceDisplayWaitVblankStart();
	sceGuDisplay(GU_TRUE);

Can you post the definition of DRAW_BUF etc?
I've try to set all buf (DRAW_BUF, DISP_BUF and DEBUG_BUF) to 512 and the results is badder than before!
All the screen is black and only little part of it is correctly show! O.O
This is my initGraphics function now:

Code: Select all

#define DEBUG_BUF (512)
#define DISP_BUF (512)
#define DRAW_BUF (512)
#define BUF_WIDTH (512)
#define SCR_WIDTH (480)
#define SCR_HEIGHT (272)
#define PIXEL_SIZE (4)
#define FRAME_SIZE (BUF_WIDTH * SCR_HEIGHT * PIXEL_SIZE)
#define ZBUF_SIZE (BUF_WIDTH SCR_HEIGHT * 2)

void initGraphics()
{
	dispBufferNumber = 0;

        sceGuInit();
        sceGuStart(GU_DIRECT,list);
        sceGuDrawBuffer(GU_PSM_8888, (void*)DRAW_BUF, BUF_WIDTH);
        sceGuDispBuffer(SCR_WIDTH, SCR_HEIGHT, (void*)DISP_BUF, BUF_WIDTH);
        sceGuDepthBuffer((void*)DEBUG_BUF,BUF_WIDTH);
        sceGuOffset(2048 - (SCR_WIDTH/2),2048 - (SCR_HEIGHT/2));
        sceGuViewport(2048,2048,SCR_WIDTH,SCR_HEIGHT);
        sceGuDepthRange(65535,0);
        sceGuDepthMask(GU_TRUE);
        sceGuDisable(GU_DEPTH_TEST);
        sceGuDisable(GU_BLEND);
        sceGuScissor(0,0,SCR_WIDTH,SCR_HEIGHT);
        sceGuEnable(GU_SCISSOR_TEST);
        sceGuFrontFace(GU_CW);
        sceGuEnable(GU_TEXTURE_2D);
        sceGuClear(GU_COLOR_BUFFER_BIT);
        sceGuFinish();
        sceGuSync(0,0);
        sceDisplayWaitVblankStart();
        sceGuDisplay(GU_TRUE);
        
	initialized = 1;
}

Are you sure YOU coded a text editor? I see a LOT of BARE BASICS missing...

[ne0h]

Yes I've coded it by myself!
Anyway I doesn't know the sceGu library, so please, can you help me?

[kralyk]

try this:

Code: Select all

#define BUF_WIDTH  (512)
#define SCR_WIDTH  (480)
#define SCR_HEIGHT (272)

void *dList;
void *fbp0;

...
	fbp0 = 0;
	dList = memalign(16, 640);

	sceGuDrawBuffer( GU_PSM_8888, fbp0, BUF_WIDTH );
	sceGuDispBuffer( SCR_WIDTH, SCR_HEIGHT, (void*)0x88000, BUF_WIDTH);
	sceGuDepthBuffer( (void*)0x110000, BUF_WIDTH);

...

And check out sdk samples, can be useful as to the GU stuff...

[Raphael]

try this:

Code: Select all

#define BUF_WIDTH  (512)
#define SCR_WIDTH  (480)
#define SCR_HEIGHT (272)

void *dList;
void *fbp0;

...

	sceGuDrawBuffer( GU_PSM_8888, fbp0, BUF_WIDTH );
	sceGuDispBuffer( SCR_WIDTH, SCR_HEIGHT, (void*)0x88000, BUF_WIDTH);
	sceGuDepthBuffer( (void*)0x110000, BUF_WIDTH);

...

And check out sdk samples, can be useful as to the GU stuff...

Please don't teach people to use uninitialized variables like that.......
if at all then do this:

void *fbp0 = 0;

And the 'correct' defines of the *_BUFs would be this:

#define DRAW_BUF (0)
#define DISP_BUF (0x88000)
#define DEBUG_BUF (0x110000)

TBH, it quite sucks to use such hardcoded values though.

PS: Who the hell named the depth buffer define "DEBUG_BUF"?

[kralyk]

oh yeah sorry, I got that line elswwhere, of course fbp0 = 0, sry, will edit that...

(hope its ok now)

Same old story... what's so fascinating about making people believe you're a software developer while in reality you're all in the world but that? When i was young, children were willing to become astronauts or super-heroes, not PSP nerds...

[kralyk]

Not knowing the GU calls makes you think the person is not a programmer?

(Im just curious, I dont wanna to say wheter he wrote it himself or not)

EDIT: I still think he might have done it: http://www.psp-hacks.com/2008/08/04/xpl ... e-manager/ (if he the same ne0h)

I've try to set all buf (DRAW_BUF, DISP_BUF and DEBUG_BUF) to 512 and the results is badder than before!
All the screen is black and only little part of it is correctly show! O.O

I used variables since my code had to deal with the TV as well as the LCD.

Code: Select all

    // set PSP screen variables
    BUF_WIDTH = 768;
    SCR_WIDTH = psp_vidout_select ? 720 : 480;
    SCR_HEIGHT = psp_vidout_select ? 480 : 272;
    FRAME_SIZE = BUF_WIDTH * SCR_HEIGHT * PIXEL_SIZE;
    DISP_BUF = 0;
    if (!psp_tv_laced)
    {
        DRAW_BUF = FRAME_SIZE;
        TEX_BUF = DRAW_BUF + FRAME_SIZE;
        DEBUG_BUF = TEX_BUF + 64*4*576;
    }
    else
    {
        DRAW_BUF = 0; // not double buffered
        TEX_BUF = FRAME_SIZE;
        DEBUG_BUF = TEX_BUF + 64*4*576;
        LACE_BUF = (uint32)sceGeEdramGetAddr() + DEBUG_BUF + 512*4*8;
    }

DISP_BUF and DRAW_BUF are your two double-buffers. TEX_BUF was a small space I used for millions mode refresh. DEBUG_BUF was the offset for the debug printing, and LACE_BUF is the interlaced framebuffer if you were using the TV in interlaced mode. Interlaced mode also implied no double-buffer, so DRAW_BUF was 0. All those buffers (except LACE_BUF) are offsets from the start of video EDRAM.

No, it's not that (even if someone willing can open documentation and see by himself) ...he's one of our old stories... anyway i was speaking of children in general...
Apart from the fact that an optimistic 1/10 of people posting here are "programmers" for their formation at university or work, a 4/10 serious hobbyists and the remaining 5/10... well, you know.

[ne0h]

Thanks kralyk, yes, Xplora is a my project (and I've writed it by myself),
I'm working on the Text editor for Xplora 1.6! :)
Anyway thanks...

Sorry, but I've still problems! :(
This is my initGraphics function now:

#define SCR_HEIGHT (272)
#define PIXEL_SIZE (4)
#define FRAME_SIZE (BUF_WIDTH * SCR_HEIGHT * PIXEL_SIZE)
#define ZBUF_SIZE (BUF_WIDTH SCR_HEIGHT * 2)

void initGraphics()
{
	dispBufferNumber = 0;
        
        void *dList;
        void *fbp0;
        
        fbp0 = 0;
        dList = memalign(16, 640);

}

Please, excuse me...

Missing a "*" in ZBUF_SIZE.

[ne0h]

Thanks to all, but I've resolved, I've ported the danzeff osk under graphics.c library(simply replaced the blit function with blitAlphaImageToScreen), I'll post the source soon ( now I've to finish the 1.6 of Xplora! )
Thanks you guys!

mm, it makes me wonder
