HimalayaBattery

Battery charging is controlled through PXA GPIO63 (HimalayaGPIO).

After implementing a driver I realized that TSC2200 does not measure battery voltage. Now comes what we learn from battery.dll:

Other more or less interesting things in battery.dll :

  • One can enable battery logging by creating the following key in registry :
	HKLM\SOFTWARE\Drivers\Battery\EnableLog = 0x1

Other key :

	HKLM\SOFTWARE\Drivers\Battery\LogTime = 0x1

After soft reset you will have \Storage\battlog.txt

	1.ID=301fffffff8f631000ffffff9d
	ACR=4973,pACR=4973,TAD=6200,LLCC=0
	FL=1247,Flg=8,RTC=820864744
	2.ID=301fffffff8f631000ffffff9d
	ACR=4974,pACR=4974,TAD=6200,LLCC=0
	FL=1247,Flg=8,RTC=820864755
	3.ID=301fffffff8f631000ffffff9d
	ACR=4976,pACR=4976,TAD=6200,LLCC=0
	FL=1247,Flg=8,RTC=820864765
	4.ID=301fffffff8f631000ffffff9d
	ACR=4977,pACR=4977,TAD=6200,LLCC=0

ACR grows when battery is charging, and goes down when discharging.
