util_battery_1.nxc

This is an example of how to use the BatteryLevel function.

//  Display battery voltage for four seconds.
// This version does not use floats and will work on NXTs with firmware 1.07.

// Note: the BatteryLevel API call returns an unsigned integer giving the 
// battery level in millivolts.
task main()
{
   unsigned int millivolts = BatteryLevel();
   unsigned int int_volts = millivolts / 1000;
   millivolts %= 1000;
   string left = FormatNum("Battery: %d", int_volts);
   string right = FormatNum(".%03d", millivolts);
   TextOut(0, LCD_LINE2, StrCat(left, right), true);
   Wait(SEC_4);
}
