GP2X Battery State

[efegea]

Hi,

I'm developing a menu replacement, and I want to add a battery status indicator.

I think squidge released time ago some information about getting the battery status, but I can't find it. I've also searched on the wiki but I did'nt found anything interesting

How can I get the status?

/dev/batt0, I think? It's /dev/something to do with battery.

Here you can find some code for it
http://wiki.gp2x.org/wiki/Devbatt
I use similar code for gnuboy2x

int batterycharge(void)
{ 
  int devbatt;
  unsigned short currentval=0;
  devbatt = open ("/dev/batt", O_RDONLY);
  read (devbatt, &currentval, 2);
  close (devbatt);
  return (currentval);
}
