 Posted: Tue Jul 19, 2005 4:50 pm Post subject: Fonction Source Code |
 |
|
First, i have to say that i'm new to psp programming (but not new to programming) and i was looking at the irda source code. I saw pspDebugScreenInit() and i looked at the pspdebug.h header file. I was wondering if the source of this fonction can be found as source or is it already pre-compiled? I'm just curious and i want to see what functions does because usually i had the .c file with the header file.
Thanks

I did a search in the whole cygwin folder and didn't find any scr_printf.c file nor any .c file at all (except in Sample).

| just found out that i didn't have the sources... so they must be already compiled... in linux, what's the equivalent of a dll with pre-compiled code? |

yes, a dll type shard library is known as a shared object, extension .so
you could just grab the sources via svn,
| Code: | | svn co svn://svn.pspdev.org/psp/pspsdk |

Thx. So if i don't have the sources, where is the pre compiled code the compiler gets his fuctions from? I son't see any .so or .c files....

scr_printf.c :
| Code: | void pspDebugScreenInit()
{
X = Y = 0;
/* Place vram in uncached memory */
g_vram_base = (void *) (0x40000000 | sceGeEdramGetAddr());
sceDisplaySetMode(0, PSP_SCREEN_WIDTH, PSP_SCREEN_HEIGHT);
sceDisplaySetFrameBuf((void *) g_vram_base, PSP_LINE_SIZE, PSP_PIXEL_FORMAT, 1);
clear_screen(bg_col);
init = 1;
} |

Yeah, i finally found them by downloading the sources from the server.
Now what i can't find anywhere is the sceDisplay* Functions source code....
I might be asking too many questions, but i've been working with uC and windows programming and usually i'm very close to the hardware i program for and i know anything i need to know.
Sorry. |

The sce*-functions are provided by the Sony PSP kernel firmware. If you have the source code of it, let me know ;-) |

| so basically, the sce functions are in the firmware and you send data at this address with the required parameters or you put the values in a accumulator and call the function... |

basically, if you want source code of sceDisplay* functions so badly, you MUST need to sign a NDA* with SONY and buy a very expensive licence.

First, why would you need the source of those functions? the sceDisplay* functions aren't that interesting anyway.... They just interface with the LCD controller, sceLcdc..............
The only use of their disassembly would only be, in my opinion, to execute code on the Me, since you can't call sce* functions directly... |
