4th brightness level...

[XazZ]

Hi...
I've been looking around some forums and google but I couldn't find an answer

OK, here comes my problem:
I wanna set the 4th screen brightness level without having the AC-adapter plugged in...
Can I do this with my own little app too? (I mean is there a function that does this for me)

Thanks in advance

Register with the irShell forum and ask Ahman, because the latest
version of irShell can do it. I would suspect it requires kernal mode.

Sorry I can't help with how it is actually done.

sceDisplaySetBrightness? :)

No problem...
Kernel mode is not the problem ;)

And thanks for the hint with irShell - I'll register with Ahman's forum and ask there

sceDisplaySetBrightness? :)

first thing: good idea :)
second thing: I couldn't find any documentation about it....
I've played with it a bit and I found out that this code:

Code: Select all

		sceDisplaySetBrightness(0,0);

seems to work....

But I'm not sure witch header files have to be included
I've tried these basic ones:

Code: Select all

#include <pspkernel.h>
#include <stdio.h>
#include <pspctrl.h>

Oh, and I haven't changed the makefile, so it still uses the "standard" libs...

EDIT: Think before you klick on Submit!
The most important output - my compilers error message:

Code: Select all

main.o: In function `main':
main.c:(.text+0x20): undefined reference to `sceDisplay_driver_9E3C6DC6'
main.c:(.text+0x3c): undefined reference to `sceDisplay_driver_9E3C6DC6'
main.c:(.text+0x54): undefined reference to `sceDisplay_driver_9E3C6DC6'

You have to stub the function in sceDisplay.S and recompile the display lib.

[weltall]

it's a kernel only function as it's part of the diplay_driver library

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

thanks weltall...
I already had this code

Code: Select all

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

so I added -lpspdisplay_driver to the libs in the makefile - and it (almost) works...

@pspwill: I didn't had to reconfigure the display-lib... - and that is good, because I'm still a beginner

I just need to figure out the values for sceDisplaySetBrightness - I can't find any documentation about it...
and my sceDisplaySetBrightness(0,0); isn't working...

thanks

You have args right here.....
0 to 100 is the 1st arg, brightness.....
2nd has to be 0 :)

Code: Select all

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