Hi! :)

Sorry to bother with maybe a stupid question, but I cannot get sceDisplaySetBrightness to work. :(

I updated my toolchain and now the display_kernel.h defines the two functions sceDisplaySetBrightness and sceDisplayGetBrightness.

What I understood:
1.Program must be kernel mode
2.sceDisplayGetBrightness(&curBrightness, NULL); reads current brightness
3.sceDisplaySetBrightness(brightness, 0); sets the display brightness.
4.In the makefile there must be LIBS += -lpspdisplay_driver

I wrote a little test program. It compiles with no warnings but it crashes.
I commented the lines (found here in onother thread)
Code:
void sceDisplay_driver_9E3C6DC6(int a0,int a1);//a0 0-100,a1 = 0/1 (set to 0)
#define sceDisplaySetBrightness sceDisplay_driver_9E3C6DC6
void sceDisplay_driver_31C4BAA8(int *a0,int *a1);
#define sceDisplayGetBrightness sceDisplay_driver_31C4BAA8

because in display_kernel.h now there are sceDisplayGetBrightness and sceDisplaySetBrightness.

Can someone please help me?

Here's my code:
Code:

#include <pspkernel.h>
#include <pspctrl.h>
#include <pspdebug.h>
#include <psppower.h>
#include <pspdisplay_kernel.h>

PSP_MODULE_INFO("Brightness Test ", 0x1000, 1, 1);
PSP_MAIN_THREAD_ATTR(0);

/* 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;
}

/* Sets up the callback thread and returns its thread id */
int SetupCallbacks(void) {
          int thid = 0;

          thid = sceKernelCreateThread("update_thread", CallbackThread, 0x11, 0xFA0, 0, 0);
          if(thid >= 0) {
                    sceKernelStartThread(thid, 0, 0);
          }

          return thid;
}

int main() {
        scePowerSetClockFrequency(222, 222, 111);

          pspDebugScreenInit();
          SetupCallbacks();

        pspDebugScreenSetTextColor(0xffffff);
        pspDebugScreenSetBackColor(0x000000);
        pspDebugScreenInit();
        pspDebugScreenSetXY(0, 0);
        pspDebugScreenPrintf("Brightness test");

        int curBrightness = 0;
        SceCtrlData pad;
        sceCtrlSetSamplingMode(PSP_CTRL_MODE_ANALOG);

        sceDisplayGetBrightness(&curBrightness, NULL);
        //curBrightness = 60;

        pspDebugScreenSetXY(0, 23);
        pspDebugScreenPrintf("Press L or R to change brightness");
        pspDebugScreenSetXY(0, 24);
        pspDebugScreenPrintf("Press TRIANGLE to exit");

        while(1) {
         pspDebugScreenSetXY(0, 15);
         pspDebugScreenPrintf("Current brightness: %3.3i", curBrightness);            

         sceCtrlReadBufferPositive(&pad, 1);
         if(pad.Buttons & PSP_CTRL_LTRIGGER) {
            if (curBrightness > 0){
               curBrightness--;
               sceDisplaySetBrightness(curBrightness, 0);
               sceKernelDelayThread(100000);
            }
         }else if(pad.Buttons & PSP_CTRL_RTRIGGER) {
            if (curBrightness < 100){
               curBrightness++;
               sceDisplaySetBrightness(curBrightness, 0);
               sceKernelDelayThread(100000);
            }
         }else if(pad.Buttons & PSP_CTRL_TRIANGLE) {
            break;
         }
        }
        sceKernelExitGame();
        return(0);
}


What I'm doing wrong?
Many thanks

P.S. Sorry for my english. :)

I'll try, many thanks for your reply. :)
You're saying I can use the brightness functions only in a graphic application, and not in a "plain debug" app?

Code:
void sceDisplay_driver_9E3C6DC6(int a0,int a1);//a0 0-100,a1 = 0/1 (set to 0)
#define sceDisplaySetBrightness sceDisplay_driver_9E3C6DC6
void sceDisplay_driver_31C4BAA8(int *a0,int *a1);
#define sceDisplayGetBrightness sceDisplay_driver_31C4BAA8


Do you have -lpspdisplay_driver in your makefile on the LIBS line?

It works for me in a debug screen app.

Yes, I have this LIB:
Code:
LIBS = -lpsppower -lpspdisplay_driver


I tried the lines above, but with the new sdk (I updated it some days ago) the program won't copile.
In pspdisplay_kernel.h there are defined directly sceDisplayGetBrightness and sceDisplaySetBrightness, I think before there were sceDisplay_driver_9E3C6DC6 and sceDisplay_driver_31C4BAA8.

So I included pspdisplay_kernel.h...

This way the program compiles, but crashes as soon as sceDisplayGetBrightness is executed.
I don't know what to check! ;)

Wow, many thanks.
This way I can undestand if the problem is my program or my toolchain. :)

Tested: works! :)
I'll check my program and your code.
Many thanks for your help. :)

EDIT: Modified my makefile and just added -lpspgu
Code:
LIBS = -lpspgu -lpspdisplay_driver -lpsppower


Now works! :)
Many thanks again.
