Detailed Description

This module provides battery monitor task handle.

REVISION

• 09/26/2003 M.GAO
  Initial creation.
• 01/29/2004 M.GAO
  Added battery voltage display hidden feature.
• 02/01/2004 M.GAO
  Always blink battery when it is low. Set system level low battery flag.
• 02/08/2004 M.GAO
  Power plug/unplug messages can not be thrown away when message queue is full.
• 03/08/2004 M.GAO
  Battery calibration code needs to access battery data.
• 04/30/2004 M.GAO
  Force to shut down if battery is too low even with the power plugged.
• 05/07/2004 M.GAO
  Adjust battery level definition to make sure battery icon blink before reporting low battery.
• 06/03/2004 M.GAO
  Make low battery threshold adjustable for HDD backpack.

Function Documentation

unsigned long BAT_deltaAvg (  void   )

Return current battery average data. Returns: Current battery average data in terms of time resolution. Definition at line 285 of file BAT_main.c. { return ((UINT32)TIM_resolution*(UINT32)DeltaAvg); }

void BAT_main (  void   )

Function serves as battery monitor task handle. This will update the battery structure accordingly and the results can be pulled from this structure. Definition at line 206 of file BAT_main.c. References battery::Flags, SBATLEVEL_UPDT, and SYS_plugSenseDet(). Referenced by KBD_main(). { SYS_plugSenseDet(); BAT_stackassert(BAT_MAIN); // Now, there's really not reason to calculate the average and voltage // more than every 0.5 seconds. Therefore, only calculate the voltage // and ultimately update the display when bat_swi.c tells us to // (i.e. pDelta = &BatteryData.Delta[0]; if (pDelta == &Delta[0]) { _batCalculate(); if(SYS_HF_battery()) { BatteryData.Flags |= BAT_HIDDENFEATURE; mMSG_send(sysMsgQ, SYS_MSG_ID, SBATLEVEL_UPDT, 0x1234, 0); } else if(BatteryData.Flags & BAT_HIDDENFEATURE) { BatteryData.Flags |= BAT_HIDDENFEATURE_EXIT; BatteryData.Flags &= ~BAT_HIDDENFEATURE; } } // Initiate another measurement OldTime = TIM; _setBatlevel(0); // set battery level to input }
