Is there any way I can check the PSPs Mac code and print it on screen?

Thanks.
-Aura

---

Yes their is a way.

Code:

---

unsigned char mac[8];
sceWlanGetEtherAddr(mac);
pspDebugScreenPrintf("Mac: %02X:%02X:%02X:%02X:%02X:%02X\n", mac[0], mac[1], mac[2], mac[3], mac[4], mac[5]);

Make sure you're including pspwlan.h too.

@MrChoas: You use FrameCounter as the index for the array MenuImages. When it is 5 or more, it goes beyond the range of the array.

Your problem is right here:

Code:

---

        if (pad.Buttons & PSP_CTRL_DOWN)
      {
      FrameCounter ++;
 
      if (FrameCounter > 5)        // Wrong  condition
        FrameCounter = 5;        // Wrong value
      }
      }

Yes their is a way.

Thats ugh... informative... now could someone tell me how to do it, or point me in the direction of some source code or something that does this please?

-Aura

Damn your blind.
IWN posted the code above. Duh.

I don't feel like handing people code when they can look at the pspwlan.h file and get the info needed.

Then dont post pointless things. You could have told him to go and look at that specific header

Here's the way I stop key-repeat. It doesn't allow any key-repeat at all, which is a bit limited. Some libraries take care of key-repeat for you and have it automatically repeat after a while.

Code:

---

// before the main loop
unsigned long lastKeys = 0L ;
SceCtrlData pad ;

// at the beginning of the main loop
sceCtrlReadBufferPositive(&pad, 1) ;
unsigned long keysPressed = (pad.Buttons ^ lastKeys) & pad.Buttons ;
unsigned long keysReleased = (pad.Buttons ^ lastKeys) & lastKeys ;

// at the end of the main loop
lastKeys = pad.Buttons ;

---

After doing this, keysPressed will give you the keys which have just been pressed and keysReleased will give you the keys which have just been released. I find it makes your code simpler because instead of:

Code:

---

if ((pad.Buttons & PSP_CTRL_DOWN) && !(oldPad & PSP_CTRL_DOWN))

---

you just have:

Code:

---

if (keysPressed & PSP_CTRL_DOWN)

---

(Unless there's an easier way)

Someone already told me that, so I fixed it.

It still moves way to fast, I'ma just use lastpad.

Anyone know the code to execute the UMD?

im using oldpad... its nearly same as in LUA :D

or
for(int loop = 0; loop > 5; loop++) sceDisplayWaitVblankStart ();
if u work with two loops

in c

int loop;
for(loop = 0; loop<5; loop++)
sceDisplayWaitVblankStart ();

or as raphael showed use C99 for use in c;)

thats not what i was trying to show. your loop won't be activated, ever

the for loop is only run if the second expression, the test condition, is true

uh wtf?
for(int loop ....
is c++
(in c it is int loop; for(loop....

but you can use it in c if you do something with c99, never tried anyway

Look at the bolded section again.

I'm not sure if anyone caught my question. I'm looking for a code to execute the UMD in the umd drive. (I looked in pspsdk, but found no examples).

first result on google:

Code:

---

int i;
i = sceUmdCheckMedium(0);
if(i == 0)
{
  sceUmdWaitDriveStat(UMD_WAITFORDISC);
}
sceUmdActivate(1, "disc0:/");
sceUmdWaitDriveStat(UMD_WAITFORINIT);
sceKernelLoadExecVSHDisc(PATH, NULL);

Hey guys, i haven't been here in a while, but i have a problem with installing freetype (i had to reinstall cygwin). I have been following this guide: http://forums.qj.net/f-psp-developme...n-c-47934.html.
When i do

Code:

---

svn co svn://svn.ps2dev.org/psp/trunk/freetype

everything is fine. But when i try

Code:

I get this error:

you havent declared path as a variable. maybe put char PATH[256] = "disk0:/folder/boot.bin" or w.e

Anyone?

Do you have the autotools installed? (autoconf and automake)

Zitat von JaSo PsP

That works, but now these are undefined refrenses:

sceUmdWaitDriveStat(UMD_W AITFORDISC);
sceUmdActivate(1, "disc0:/");
sceUmdWaitDriveStat(UMD_W AITFORINIT);

I had a feeling there was a huge chunk of missing code. :(

looks like you have to #include something else

Yeah, that's what I was thinking...Idk what though.

Which makefile line do I put it on?

Libs?

Zitat:

Zitat von _dysfunctional

Libs?

Wow, thanks it worked. (Sorry, I never messed with my makefile before, thats why I didn't know).

suppose:

Code:

---

char oh_hellow0rld[20][40]= {"39 chars max long","19  SUCH STRINGS" }

---

or

Code:

---

char oh_hellow0rld[20][40]= {"19 chars max long","39 SUCH STRINGS" }

Did anyone get what I'm sayin?

dindt really understand him:p

it was to fast written;)

Code:

---

char oh_hellow0rld[20][40];

---

That is an array of 20 strings, 40 characters per string.

Code:

---

#include <stdio.h>
#include <stdlib.h>

int main()
{
        char helloWorld[3][10] = { "Hello", " ", "World!" };

        printf("%s%s%s\n", helloWorld[0], helloWorld[1], helloWorld[2]);
        return 0;
}

That will print, "Hello World!".

Neither one. 20 char*s each with 40 chars (but only 39 are usable if you're using them a C strings)

sorry, i was actually playing around with the functions in pspumd.h myself and just forgot to tell you about putting LIBS= -lpspumd in the makefile.

anyway did the code load a umd for you?
