I've been wondering if this is possible. I know its possible to turn off the WLAN, MS, and POWER LED's but is it possible to turn off the orange "charge" LED when A/C adapter is plugged in?

I've searched but couldn't find anything.

This is the code for the LEDControl plugin.

Code:

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

#define MS_LED 0
#define WLAN_LED 1
#define POWER_LED 2

#define STATE_ON 1
#define STATE_OFF 0

PSP_MODULE_INFO("LEDControl", 0x1000, 1, 0);
PSP_MAIN_THREAD_ATTR(0);
int currentState = STATE_ON;

int main_thread(SceSize args, void *argp)
{   
   SceCtrlData pad;

   while(1)
   {
      sceCtrlReadBufferPositive(&pad, 1);
      if(pad.Buttons & PSP_CTRL_LTRIGGER) {
         if(pad.Buttons & PSP_CTRL_VOLDOWN)
         {
            if(currentState == STATE_ON)
            {
               sceSysconCtrlLED(MS_LED, STATE_OFF);
               sceSysconCtrlLED(WLAN_LED, STATE_OFF);
               sceSysconCtrlLED(POWER_LED, STATE_OFF);
               currentState = STATE_OFF;
            }
            else
            {
               sceSysconCtrlLED(MS_LED, STATE_ON);
               sceSysconCtrlLED(WLAN_LED, STATE_ON);
               sceSysconCtrlLED(POWER_LED, STATE_ON);
               currentState = STATE_ON;
            }
         }

      }
          sceKernelDelayThreadCB(100000);
   }

   return 0;
}

int module_start(SceSize args, void *argp)
{
   // Create a thread
   int thid = sceKernelCreateThread("LEDControl", main_thread, 0x30, 0x1000, 0, NULL);
   if(thid >= 0) sceKernelStartThread(thid, args, argp);

   return 0;
}


Maybe its a hardware thing and it can't be controlled by software?

Yes it can be done.
Have a look at Road Dog source.
I got the sample from this forum.

It might be just a matter of defining the next LED:
Code:

#define CHARGE_LED 3


or maybe not, but Road Dog definitely turns it off.

I tried
Code:
#define CHARGE_LED 3
and it doesn't work.

I looked at main.c of Road Dog but couldn't really tell why it does work and why mine doesn't.

Maybe it's a 1.50 kernel mode thing?
I can't say for sure why, just know it does turn it off for me.
It could also be because my toolchain is a very old version.

I can still adjust LCD brightness, yet others here have had
problems with the same sample code to do that.
