C/C++ Programming Help Thread

The XMB does a lot of different things, and you should avoid calling those certain functions, best suggestion would be to look at the source code from the DSX library so you have some idea of what needs to be done. It would be best to look at how to draw a rectangle, as I think its a bit more detailed than the font.

Can any suggest what I need to do in order to load an alternative pspbtcnf.bin file, its still plauging me?

Quick question:
I have the oggplayer.c and .h files, but how do i install the libs and what do i put in my makefile? I searched insomniac's website, but his ogg player page wasn't opening. Thanks! ;)

[Auraomega]

You just add the .o files to the "OBJS" section, for example:

TARGET = TARGET_NAME
OBJS =\
main.o\
oggplayer.o

and then include oggplayer.h in the headers...

I have libtremor saved, but i click "make install" and nothing happens.

[Slasher]

You should be cd'ing' into the libtremor folder with cygwin, and then typing 'make' then 'make install'

[SuperBatXS]

I did that. But i found out how to work it. In fact, i also encountered something amazing!!!

Installing now....after all those years.........

-= Double Post =-

Ok, i installed libogg. Then libTremor. However, when i put "-lTremor" in my include file, the program says it can't find it (already followed the README.PSP)...?
Could anyone please help?

Still Struggling with this!!

Does anyone know anything about time-based animations?
I need to know some function that returns a time or something...

Look in:

X:/cygwin/usr/local/pspdev/psp/sdk/include/psprtc.h

or

X:/cygwin/usr/local/pspdev/psp/include/time.h

The first are PSP specific functions, where the ones are universal for all C/C++.

Agh....after so many hours of waiting for an answer, i thought this was a response to my question. :Argh:

Agh....after so many hours of waiting for an answer, i thought this was a response to my question. :Argh:

Don't complain, I've been asking for a few days about how to load a pspbtcnf file, and no reply...

I've got this so far, I basically copied from the 3.40OE-A source code, and commented out the stuff I didn't need, but no luck:

    struct SceKernelLoadExecVSHParam param;
	//u32 vshmain_args[0x20/4];

	memset(&param, 0, sizeof(param));
	//memset(vshmain_args, 0, sizeof(vshmain_args));

	//vshmain_args[0/4] = 0x0400;
	//vshmain_args[4/4] = 0x20;
    //vshmain_args[0x14/4] = error;

	param.size = sizeof(param);
	//param.args = 0x400;
	//param.argp = vshmain_args;
	//param.vshmain_args_size = 0x400;
	//param.vshmain_args = vshmain_args;
	param.configfile = "/kn/pspbtcnf_p4bu.bin";

Am I missing something blindingly obvious?

funcLib can make programming easier and more fun, if you'd check it out here I'd be happy.

Hey guys,
So i gave up on libogg since i couldn't get it installed. However, i tried using an mp3 decoder by cooleyes (http://forums.ps2dev.org/viewtopic.p...=mp3&start=30), and i always get this error:
undefined reference to sceAudiocodecCheckNeedMem .

If anyone could help me on this. Also, i tried to put comments on those lines that got me an error, and it compiled perfectly. I then ran the program, and the home button was working fine except the mp3 wasn't playing. Could someone please help? I am still having problems getting decent speed with my mp3's (without overclocking psp).

If you can help me get either this mp3 decoder or libogg working, i will NEVER forget you...

[Archaemic]

I've gotten it working before...I can't see why I can't get it working now ._.

That should have done it. Still same error?

...also, why are you still linking libmad?

[SuperBatXS]

Yes, i am linking libmad. New makefile:

TARGET = hello
OBJS = main.o

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

LIBDIR =

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

And thanks a LOT for trying to help! ;)
And same error, btw.

[Judas]

Don't forget that some libs are reliant on others, so you may need to re-arrange the libs in order for it to work correctly.

[SuperBatXS]

I just realized that, and i reordered my libs:
-lpsppower -lpspmpeg -lpspaudiocodec -lpspaudio -lm

That's the order in the makefile of the example of the mp3 decoder. However, even then i am getting the same error. I must be missing a file (no other logical reason). What files should i reinstall/install?

Can you post your exact errors? (Or link to them if they've already been posted?)

[SuperBatXS]

Thank you for helping me!

[Archaemic]

make clean and then make and post the full results of that.

[SuperBatXS]

Edit: Never Mind b/c.....
I finally got libogg working!!!

This is WAY smoother than libmad. It doesn't seem to slow down the FPS of my game at all.

I have an electronics exam coming up after my January exams, and I'm basing certain parts on the PSP (hopefully), and I was wondering if anyone who knows about the remote control can tell me how fesible this is:

I load an app to read the remote control ports, and send a serial input at a relatively fast speed (about 1MHz) and after reading the inputs, decode it and display the data on the screen. I can make the app easy enough, but I'm not sure about the hardware, mainly, does the remote send a pulse, or does it infact send a series of pulses when a button is pressed? Is there anyway I could detect this? And is there any connectors that I can use to place in the headphone port, other than either making my own or disecting the supplied remote?

If anyone could help me I would be seriously thankful as I'd like to start work on it now :)

Thanks
-Aura

[Xsjado7]

i think on ps2dev (i think) i saw a bit about some guys who pulled a part the headphone jack and stuff and had a whole stack of info and stuff about. i cant remember if it had anything about what your asking but it might be worth doing a search there

[Auraomega]

Cheers, definatly sounds like the sort of thing I'm looking for, I'll take a look :)

Hey guys,
I just put my app into kernel mode, but now the home exit button doesn't work. Btw, i am using 3.52 M33, and i have my eboot in the GAME150 folder. Here is my callback:

/* exit callback */
int exit_callback(int arg1, int arg2, void *common){
	sceKernelExitGame();
	return 0;
}

/* callback thread */
int CallbackThread(SceSize args, void *argp){
	int cbid;
	cbid = sceKernelCreateCallback("Exit Callback", exit_callback, NULL);
	sceKernelRegisterExitCallback(cbid);
	sceKernelSleepThreadCB();
	return 0;
}
/* setup the callback thread */
int SetupCallbacks(void){
	int thid = 0;
	thid = sceKernelCreateThread("update_thread", CallbackThread, 0x11, 0xFA0, 0, 0);
	if(thid >= 0)
		sceKernelStartThread(thid, 0, 0);
	return thid;
}

[Archaemic]

Change the attributes of the thread so it starts in user mode.

The remote port is a basic serial port:
http://nil.rpc1.org/psp/remote.html

there are already nice functions for sending/recieving data from the serial port
look into the debug utility library and you'll find:
void pspDebugSioPutchar (int ch)
Put a character to the remote sio.
int pspDebugSioGetchar (void)
Get a character from the remote sio.
void pspDebugSioPuts (const char *str)
Write a string to the sio port.
int pspDebugSioPutData (const char *data, int len)
Write a set of data to the sio port.
int pspDebugSioPutText (const char *data, int len)
Write a set of data to the sio port converting single line feeds to CRLF and single CR to CRLF.
void pspDebugSioInit (void)
Initialise the remote SIO port (defaults to 4800 8N1).
void pspDebugSioSetBaud (int baud)
Set the baud rate of the SIO, e.g.

If you want to read input from the remote control see http://psp.jim.sh/pspsdk-doc/group__Hprm.html

[Auraomega]

Thanks, the first link doesn't appear to work...

I'm looking mainly for a pinout connection, including the voltages required (I don't want to put more voltage into the PSP than is safe), and I'd like to find out what the minimum amount of pulses I can recieve is, say around a nibble (I don't need many options, maybe enough for BCD to make decoding easier).
