Some problems with sceCtrlData...

[blu_eye4]

Hi guys! :)

I'm blu_eye4, a new italian user so, if my english is bad, excuse me...

Well, I'm a beginner coder and I'm learning C programming language: I'm not learn it at school, so I don't know many things and feature...


This is the code:

Code: Select all

#include "pspkern.h"
#include <pspkernel.h>
#include <pspiofilemgr.h>
#include <pspctrl.h>
#include "dump.h"
#include <psppower.h>

PSP_MODULE_INFO&#40;"esercitazione", 0, 1, 0&#41;;
#define printf pspDebugScreenPrintf

int sceIoRead&#40;SceUID fd, void *data, SceSize size&#41;;
int *getcwd&#40;char *buffer, size_t length&#41;;
int sceDisplayWaitVblankStart&#40;&#41;;
int sceIoMkdir&#40;const char *dir, SceMode mode&#41;;
int main&#40;void&#41;
&#123;
    SceCtrlData pad;
    int done = 0;
    pspDebugScreenInit&#40;&#41;;
    pspDebugScreenClear&#40;&#41;;
    SetupCallbacks&#40;&#41;;
    char path&#91;256&#93;;
    getcwd&#40;path, 256&#41;;
    printf&#40;"Siamo nella directory %s\n\n", path&#41;;
    printf&#40;"premere X per cambiare frequenza cpu e bus\n"&#41;;
    printf&#40;"premere O per dump memoria\n"&#41;;

    for&#40;;;&#41;&#123;
            sceCtrlReadBufferPositive&#40;&pad, 1&#41;;
    if&#40;pad.Buttons != 0&#41;&#123;
    if&#40;pad.Buttons & PSP_CTRL_CROSS&#41;
    &#123;
        scePowerSetClockFrequency&#40;100,100,50&#41;;
        printf&#40;"frequenza attuale cpu&#58; %d mHz\n", scePowerGetCpuClockFrequency&#40;&#41;&#41;;
        printf&#40;"frequenza attuale bus&#58; %d mHz\n", scePowerGetBusClockFrequency&#40;&#41;&#41;;
    &#125;
    if&#40;pad.Buttons & PSP_CTRL_CIRCLE&#41;
    &#123;
        dump_memory&#40;&#41;;
        printf&#40;"\n\nFatto\n\n"&#41;;

    &#125;
    &#125;
    sceDisplayWaitVblankStart&#40;&#41;;
    return 0;
&#125;
&#125;

It is a simple homebrew who want dump memory. Cygwin can compile it and it doesn't give me any warning or error, but when I play the homebrew on my psp there is a problem: buttons doesnt't work...
Why? How can I resolve?

Thanks a lot for your time and excuse me if there are some grammatical errors :)


ah... I've given some of code from SDK... the dumping function is given from the example...

[Torch]

return 0 is inside the for loop :P

[blu_eye4]

oh... now it work, but I would know how print once a thing: if I press X, the homebrew printf a lot of times the cpu frequency... How would I do?

Thank a lot

Make a copy of the pad.Buttons and compare it with the new value to see if buttons have changed, or if just being held down.

Or use sceCtrlReadLatch. You can detect when the button is first pressed, being held down, and released.

Ok, now the dumping function doesn't work, I press the button, on the screen i read "dumping 28 Mb..." but after 20 seconds the psp shut down...
I don't understand the problem, I've seen the example and there isn't difference. The example work, my homebrew not...

I've tried how to use sceCtrlReadLatch and I've found some documentation on doxygen, but I can't work it... please help me :)

Thank again for your time

Code: Select all

	SceCtrlLatch latch;
	sceCtrlSetSamplingCycle(0);
	sceCtrlSetSamplingMode(PSP_CTRL_MODE_DIGITAL);
	
	for(;;)
	{
		sceCtrlReadLatch(&latch);
		if (latch.uiMake & PSP_CTRL_CROSS)
		{
			....
		}
	}

uiMake is on first press only. uiBreak is on release.

All other statements are unnecessary.

Can you resolve this problem also?

Remove the
SceCtrlData pad;
and
sceCtrlReadBufferPositive(&pad, 1);
Its not needed.

You need to make your program as VSH mode like this with 0x800 flag.
PSP_MODULE_INFO("TestApp", 0x800, 1, 0);

I've understand what I have to do, but my code don't work... why?
And an other thing, availing your balminess, could you tell me how do I do to export the homebrew to kernel 3.xx? You're very aware :) and excuse me for bad english...

[Torch]

Put BUILD_PRX = 1 in the makefile.
The main program should be either 0x800 mode or 0x0 mode.

[blu_eye4]

and for flash problem do you know how I have to do? And the main program is 0x800 mode, what's wrong?

[Torch]

Look at the return values from the sce functions. See what error codes they are.
