Fx-9860 battery indicator (C)

Postby helder7 » Mon May 07, 2012 11:24 pm

I found this in interesting code in one add-in.

battery indicator
Code: Select all
// battery = 1 = main (do not use other values)
// firstlevel: warning level
// secondlevel: shutdown level
int GetBatteryStatus( int battery, int*firstlevel, int*secondlevel ){
int (*iGBS)( int ) = 0;  // declare an int function pointer
int*battconfig = (int*)0x80000334;
  *firstlevel = 0x17F;
  *secondlevel = 0x16D;
 
     switch ( OSVersionAsInt() ){
       case OS102 : iGBS = (int(*)(int))0x80032E14; break;
       case OS103 : iGBS = (int(*)(int))0x80032E80; break;
       case OS104 :
       case OS105 :
         iGBS = (int(*)(int))0x80032E5C;
         if ( *battconfig==0x43444844 ){
           *firstlevel = 0x1A5;
           *secondlevel = 0x191;
         };
         break;
       case OS1051 :
         iGBS = (int(*)(int))0x80032E44;
         if ( *battconfig==0x43444844 ){
           *firstlevel = 0x1A5;
           *secondlevel = 0x191;
         };
         break;
       case OS110 :
         iGBS = (int(*)(int))0x8003BD2C;
         *firstlevel = 0x2AA;
         *secondlevel = 0x288;
         break;
       case OS111 :
         iGBS = (int(*)(int))0x8003BCF0;
         *firstlevel = 0x2AA;
         *secondlevel = 0x288;
         break;
       case OS200 :
         iGBS = (int(*)(int))0x80039A0C;
         if ( *battconfig==0x43444844 ){
           *firstlevel = 0x1A5;
           *secondlevel = 0x191;
         };
         break;
      case OS200GII :
         iGBS = (int(*)(int))0x8003C484;
         break;
      case OS200slim :
         iGBS = (int(*)(int))0x80047FD4;
         *firstlevel = 0x2AA;
         *secondlevel = 0x288;
         break;
     };
   if (IsSlim()){
      *firstlevel = 0x2AA;
      *secondlevel = 0x288;
   }   
   if (iGBS!=0) return (*iGBS)( battery );
   else return 0;
}

// the warning level lies around 2/3 full scale
int MainBatteryPercentage( void ){
int firstlevel, secondlevel;
int i;
   if ( IsEmulator() ){
      i = 100;
      firstlevel = 70;
      secondlevel = 65;
   } else i = GetBatteryStatus( 1, &firstlevel, &secondlevel );
     
   if (firstlevel > 0 ) return ( 200*i )/(firstlevel*3);
   else return 0;
}

As for OSVersionAsInt see: http://www.casiopeia.net/forum/viewtopic.php?f=21&t=1368
There are some constants and other functions, which possibly need to be commented (f. i. IsEmulator()http://www.casiopeia.net/forum/viewtopic.php?f=20&t=1374).
I think the code needs some update, too. I'll see to it as fast as possible.

The following code fetches the pointer to the function GetMainBatteryVoltage (iGBS in the code of the previous post) OS-independently (fx-9860-OSes; verified with versions 1.03, 1.04, 1.05, 1.10, 1.11, 2.00, 2.01 and 2.02):
source: Show
Code: Select all
//
int GetMainBatteryVoltagePointer(){
unsigned int ea;
unsigned int j;
    ea = *(unsigned int*)0x8001007C;
    ea = ea + 0x049C*4;
    ea = *(unsigned int*)( ea );
    while ( *(unsigned short*)( ea ) != 0xE464 ){
      ea = ea + 2;
    };
    ea = ea + 2;
    j = *(unsigned char*)( ea + 1 );
    j = 4*j;
    j = ( ea + j + 4 ) & 0xFFFFFFFC;
    return *(unsigned int*)( j );
}

BTW:
on the Prizm the BatteryVoltage can be read with
syscall 0x1186: int GetMainBatteryVoltage( int one );
The parameter one should be always 1.

cool, could you make an add-in from it or make a tutorial on how to do that? :D

Here's the snippet:
(if you are confused by the instant syscalls, put it in a separate file and include it. The advantages of the instant syscalls are its SDK-independence and a quick prototyping. In your final system, they may reside in a library, of course)

You can call F01_1_Handler() from out of your addin_main, f. i..
I do not know, how you want to display the battery status. Hence I implemented a simple printout for now.

I know about that add-in, it doesn't work, instead it instantly comes up with a system error :(

Oh. I did not try it myself, yet. But I will now and have a look to its internals.

Edit:
I tried BATTERY.G1A on a fx-9860G (OS 1.03) and on a fx-9860GII SD (OS 2.01).
I encounter an immediate crash on both machines, too. I think it should be removed from the download area.

BTW: I hope you get along with the snippet I dropped.

Battery.g1a works in my fx9860gII sd with os 2.X (i dont know now the os version, i have my calc at home).

Yep. I just downgraded my fx-9860GII SD to OS 2.00 and Battery.G1A works as expected.

Hence I had a closer look. In fact, BATTERY.G1A uses a single jump-address 0x8003C484 to get the battery-voltage. This address is valid on fx-9860GII OS 2.00, only! And leads to a crash on any different OS.

Thanks Simon. It works, but hung (had to reset my 9860 - OS 2.00) when I used F01_1_Handler in a timer.

What parts of "F01_1_Handler" do you exactly use in your timer-handler?
