I've never writed a plugin before.

I want to know how to make a simple evil :P plugin which makes the power led goes on and off and on and off... So everone got hypnothised by that little led. But it dont work.

Here is my code:

main.c

Code: Select all

#include <pspkernel.h>
#include <pspsyscon.h>

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

int main_thread&#40;SceSize args, void *argp&#41;
&#123;
	int state = 0;
	for&#40;;;&#41;
	&#123;
		sceSysconCtrlLED&#40;SCE_LED_POWER,state&#41;;
		if &#40;state&#41; state=0;
		else state=1;
		sceKernelDelayThread&#40;100000&#41;;
	&#125;
&#125;

int module_start&#40;SceSize args, void *argp&#41;
&#123;
		// Create a thread
	SceUID thid = sceKernelCreateThread&#40;"CrazyLed", main_thread, 25, 64*1024, 0, NULL&#41;;
	if&#40;thid >= 0&#41;
	&#123;
		sceKernelStartThread&#40;thid, args, argp&#41;;
	&#125;

	return 0;
&#125;

makefile

Code: Select all

TARGET = CrazyLed
OBJS = main.o

INCDIR = 
CFLAGS = -O2 -G0 -Wall
CXXFLAGS = $&#40;CFLAGS&#41; -fno-exceptions -fno-rtti
ASFLAGS = $&#40;CFLAGS&#41;

LIBDIR =
LIBS = 

USE_KERNEL_LIBC = 1
USE_KERNEL_LIBS = 1

BUILD_PRX = 1

PSPSDK=$&#40;shell psp-config --pspsdk-path&#41;
include $&#40;PSPSDK&#41;/lib/build_prx.mak

Did i do something wrong?

I'm not sure but you may want to try Kernel prx instead of a user prx.

If you didn't notice, he is using a kernel prx already.

I think i did nothing wrong. I had it on while i was playing with PSPTube and i saw the wlan-led goes crazy. so i think i made a plugin which made the wrong led blinking.

To clear things up, sceSysconCtrlLED doesn't actually make the LEDs on or off. It only ALLOWS or DISALLOWS the particular LED to be turned on or off by other apps/system.

Suppose you sceSysconCtrlLED(WLAN, 1), the WLAN LED will not turn on. It only ALLOWS the led to blink when connection is active. Similarily sceSysconCtrlLED(MEMSTICK, 1) won't activate the orange led. It only blink when data is transferred. sceSysconCtrlLED(MEMSTICK, 0) will keep it off even during data transfer.
