sceDisplaySetBrightness and sceDisplayDisable sample

[sakya]

Hi! :)

Since it seems I wasn't the only one to have problems with these functions, here's a simple program that uses sceDisplaySetBrightness/sceDisplayGetBrightness and sceDisplayDisable/sceDisplayEnable

Code: Select all

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

PSP_MODULE_INFO&#40;"Brightness Test ", 0x1000, 1, 1&#41;;
PSP_MAIN_THREAD_ATTR&#40;0&#41;;

void sceDisplay_driver_9E3C6DC6&#40;int a0,int a1&#41;;//a0 0-100,a1 = 0/1 &#40;set to 0&#41;
#define sceDisplaySetBrightness sceDisplay_driver_9E3C6DC6
void sceDisplay_driver_31C4BAA8&#40;int *a0,int *a1&#41;;
#define sceDisplayGetBrightness sceDisplay_driver_31C4BAA8
int sceDisplayEnable&#40;void&#41;;
int sceDisplayDisable&#40;void&#41;; 

//Flag for exit from loop when user exits with HOME&#58;
static int runningFlag = 1;

// TWILIGHT ZONE! <do doo do doo>
/* Exit callback */
int exit_callback&#40;int arg1, int arg2, void *common&#41; &#123;
          runningFlag = 0;
          sceKernelExitGame&#40;&#41;;
          return 0;
&#125;

/* Callback thread */
int CallbackThread&#40;SceSize args, void *argp&#41; &#123;
          int cbid;

          cbid = sceKernelCreateCallback&#40;"Exit Callback", exit_callback, NULL&#41;;
          sceKernelRegisterExitCallback&#40;cbid&#41;;

          sceKernelSleepThreadCB&#40;&#41;;

          return 0;
&#125;

/* Sets up the callback thread and returns its thread id */
int SetupCallbacks&#40;void&#41; &#123;
          int thid = 0;

          thid = sceKernelCreateThread&#40;"update_thread", CallbackThread, 0x11, 0xFA0, PSP_THREAD_ATTR_USER, 0&#41;;
          if&#40;thid >= 0&#41; &#123;
                    sceKernelStartThread&#40;thid, 0, 0&#41;;
          &#125;

          return thid;
&#125;
// END OF TWILIGHT ZONE! <do doo do do>

int main&#40;&#41; &#123;
		  scePowerSetClockFrequency&#40;222, 222, 111&#41;;

          SetupCallbacks&#40;&#41;;

		  sceDisplaySetFrameBuf&#40;NULL,0,PSP_DISPLAY_PIXEL_FORMAT_4444, PSP_DISPLAY_SETBUF_IMMEDIATE&#41;;

          pspDebugScreenInit&#40;&#41;;

			pspDebugScreenPrintf&#40;"Current brightness&#58; %3.3i", curBrightness&#41;;				

			sceCtrlReadBufferPositive&#40;&pad, 1&#41;;
			if&#40;pad.Buttons & PSP_CTRL_LTRIGGER&#41; &#123;
				if &#40;curBrightness > 0&#41;&#123;
					sceDisplaySetBrightness&#40;--curBrightness, 0&#41;;
					sceKernelDelayThread&#40;100000&#41;;

				break;
			&#125;
		  &#125;
		  sceKernelExitGame&#40;&#41;;
		  return&#40;0&#41;;
&#125;

Makefile:

Code: Select all

TARGET = bright
OBJS = main.o
CFLAGS = -O3 -G0 -Wall
CXXFLAGS = $(CFLAGS) -fno-exceptions -fno-rtti
ASFLAGS = $(CFLAGS)
LIBDIR =

LIBS = -lpspgu -lpspdisplay_driver -lpsppower
LDFLAGS =
EXTRA_TARGETS = EBOOT.PBP
PSP_EBOOT_TITLE = Brightness Test 
PSPSDK=$(shell psp-config --pspsdk-path)
include $(PSPSDK)/lib/build.mak

Maybe it's usefull for someone else. :)
Thanks to Art for his help.

Just a question: the program works fine, but compiling it I get an "implicit declaration of function 'sceDisplayDisable'" but cannot find any header file with sceDisplayDisable declared in my sdk...

EDIT: fixed code, no more "implicit declaration..." warning. ;)

Add this:

Code: Select all

int sceDisplayEnable(void);
int sceDisplayDisable(void);

after

Code: Select all

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
