Calculates power drain for wlan, BT, Backlight etc and shows the results. Good to know, what setting consumes most of the battery power on your windows mobile / Pocket PC.
在大多2440開發(fā)板BSP中的SMDK2440\DRIVERS\backlite目錄下一般都有背光驅(qū)動。在注冊表中添加如下函數(shù)的時(shí)候，開機(jī)時(shí)確實(shí)可以打印"!!!!!!!!!!!! Backlight ON !!!!!!!!!!!!，如果沒有操作大概1分鐘后也可以打印!!!!!!!!!!!! Backlight OFF !!!!!!!!!!!!。但打印("!!!!!!!!!!!! Backlight OFF !!!!!!!!!!!!后，就算有觸發(fā)事件（在觸摸屏上點(diǎn)擊，或者移動鼠標(biāo)）也不會打印"!!!!!!!!!!!! Backlight ON !!!!!!!!!!!!。
其實(shí)這個(gè)驅(qū)動大體是正確的，只是當(dāng)鍵盤鼠標(biāo)或觸摸屏輸入時(shí)候gwes 發(fā)送“PowerManager/ActivityTimer/UserActivity” event，而不是原驅(qū)動中的“("UserInputEvent") ”修改后的源程序如下（SMDK2440\DRIVERS\backlite目錄下bak_hw.cpp文件）。
