Always ask how to set the backlight

WINCE Prawn good ! I recently decided to get a screen saver , you need to have turn on the backlight , does not automatically turn off the backlight . Lane did not get a long-N , do not know what can be done to this effect . My test machine is a PXA27 series of chips , I found even in wince inside , directly select the display backlight setting has no effect . Does such a situation how to solve it ?
------ Solution ---------------------------------------- ----
this mainly depends on your selection of the LCD , you can set up according to screen datasheet

have an average LCD ADJ pin or LCD_PWR pin is connected to your chips, you will be at program initialization pin is pulled , its inspection procedures

it where there is no right pin set , so, either pulled or to delete

If you want to control the brightness of the backlight can be connected to the ADJ pin of the PWM chip side , by adjusting the pulse width to control the backlight brightness
------ Solution -------- ------------------------------------

general driver will receive a PM power management change message , you can drive the system into useridle or suspend receipt called when your screen saver , and then exit the system state when you exit the screen saver is also on the line





------ Solution ------------------------------------ --------
driven from power management to start is the most fundamental way , but need to customize the system .

solve the problem, forgot to speaking about. I did that is used to modify the registry settings control the backlight , and before that the custom kernel is not added to the registry , so they will not work, plus go after , and now on it. Thank you for helping pull
