Depends if you have enabled double buffering or not.

void oslInitGfx(int pixelFormat, int bDoubleBuffer);

0 for single or 1 four double buffering for bDoubleBuffer

Hi,

I want to print an image onto my screen this is my code:

#include <pspdisplay.h>
#include <pspctrl.h>
#include <pspkernel.h>
#include <pspdebug.h>
#include <pspgu.h>
#include <png.h>
#include <stdio.h>
#include "callbacks.h"
#include "graphics.h"

PSP_MODULE_INFO("ufosample", 0, 1, 1);
//PSP_HEAP_SIZE_MAX();

#define printf pspDebugScreenPrintf 
#define MAX(X, Y) ((X) > (Y) ? (X) : (Y))

int ufoX = 0;
int ufoY = 0;

int main() {
    pspDebugScreenInit();
    SetupCallbacks();
    initGraphics();
    
    Image *ufo;
    ufo = loadImage("ufo.png");
    
    if(!ufo) {
             printf("You'r version of the sample is incomplete!");
             sceKernelDelayThread(100000);
             sceKernelExitGame();
    } else {

    sceDisplayWaitVblankStart();
    
    blitAlphaImageToScreen(0 ,0 ,583 , 83, ufo, ufoX, ufoY);
    flipScreen();         
    
    }
    
    sceKernelSleepThread();
    return 0;
}

TARGET = sample
OBJS = main.o graphics.o framebuffer.o

CFLAGS = -O2 -G0 -Wall
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)

LIBDIR =
LIBS = -lpspgu -lpng -lz -lm
LDFLAGS =

EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = sample

PSPSDK=$(shell psp-config --pspsdk-path)
include $(PSPSDK)/lib/build.mak

But everytime i try it on my PSP it says thhe sample is incomplete.
But im sure my ufo.png is in the same directory as my eboot.pbp?

Can someone please help me?

Try uncommenting PSP_HEAP_SIZE_MAX();

[basfreak]

Nope, don't work either.

The graphics library you're using doesn't support interlaced .PNG files. Make sure that it's not interlaced.

[basfreak]

Nope isn't interlaced :S

[starski321]

over my head lol

[Insert_Witty_Name]

blitAlphaImageToScreen(0 ,0 ,583 , 83, ufo, ufoX, ufoY);

Is the 583 argument an error?

The maximum size of a texture you can load is 512x512 using graphics.c.

[slicer4ever]

IWN! irc, NAO! have question

[basfreak]

Of course! forgot to scale my ufo down, but still doesn't work.
Arggg... going crazy!

[Insert_Witty_Name]

IWN! irc, NAO! have question

I'm at work mate, no IRC.

PM me if you need.

[slicer4ever]

ARG, alright guess i'll have to ask via forum
anywho, trying to get adhoc into one of my games, and i'm having a problem with sceNetAdhocctlAddHandler
it works fine under 4.01, and it had worked under 3.40, however one of my psp's is running 3.90 and it keeps returning error's

[Insert_Witty_Name]

What's the error it returns?

[slicer4ever]

it's returning < 0

[Insert_Witty_Name]

Obviously ;)

The exact error number would help. Use 0x%08X as the format string for printf() or whatever.

[slicer4ever]

0x8002013A

[Insert_Witty_Name]

Helped on IRC after all ;)

Alright, I've been doing some research, and I can't seem to find out how to remap the buttons (ex. Analog up = triangle). If someone could tell me of a method of how to do it, which I'm pretty sure uses button masking, what are the values for the buttons, and would it be the same values as while looking at a memory editor, every game has a controller address. (ex. Square is 0x8000).

uh.. can you not just do something like

uint32_t MyButtonAbstractUnderwear(uint32_t button)
{
    uint32_t nb = 0;

    if((button & BTN_TRIANGLE) != 0) nb |= BTN_ANALOGUE_UP;
    ....

    return nb;
}

type deal..

etc

[Insert_Witty_Name]

You need to hook the button reading functions (sceCtrl*) and replace them with your own.

I'm not aware of your skill level, but it's not really a task for someone with little programming knowledge or who's not used to hooking functions.

Also the fact that if this is used in the VSH it could cause problems with the vshctrl hook (Assuming its sceCtrlReadBufferPositive ).

I get that when I try to use pspDebugScreenPrintf()

pspDebugScreenPrintf("%-14s: %d%% (%02dh%02dm)     \n", "Charge", scePowerGetBatteryLifePercent(), batteryLifeTime/60, batteryLifeTime-(batteryLifeTime/60*60));

That's how I used it.

[NoEffex]

I have the same exact problem. The only difference is that I'm trying to load up the psp's keyboard, yet it will not compile because of the printf errors. Same as QJ's,

That's how I used it.

I guess you're linking against KERNEL_LIBC? In that case you can't use pspDebugScreenPrintf for the sole reason that it depends on vsnprintf from varargs, which isn't in kernel libc. You'd have to create a macro to wrap the variable arguments into a sprintf like that:

   #define pspDebugScreenPrintf(...) { char buf[256]; sprintf(buf,__VA_ARGS__); pspDebugScreenPuts( buf ); }

If you have lines that may exceed the 256 chars increase the buf.

[Anti-QuickJay]

Yea I was thanx alot for the help Rapheal.

[NoEffex]

So, in that conclusion, it would not be possible(or require a lot of bs) to load the sce keyboard...Ex.

pspDebugKbInit(buffer);

because that whole thing is a printf whore.

You could recompile pspdebug.a with the macro I posted. With that it should work. Just don't define the macro inside scr_printf.c or pspdebug.h.
-=Double Post Merge =-
I just noticed, there's already a special kernel mode printf function in pspdebug:
pspDebugScreenKprintf

So Anti-Quickjay you can just use that function instead and NoEffex, you still have to recompile pspdebug, but can just put this define at the top of pspdebugkb.c:

#define pspDebugScreenPrintf pspDebugScreenKprintf

Thanks, I just went ahead and grabbed the thing out of the pspsdk source, since my thing is ever-so-open-source, I don't think many people will be able to compile if I do otherwise. Nevertheless, thank you very much.
EDIT: It requires snprintf, which is not available with the kernel crap. Is there a macro available to emulate what it does?

pspDebugScreenKprintf requires snprintf? You sure you have the right code? :) pspDebugScreenKprintf only uses prnt, which is a kernel function, so it *really should* work.
Else you're open to use my previous macro that uses sprintf (not snprintf).
