EP9307  backlight off problem

Note: This was originally posted on 14th July 2011 at http://forums.arm.com

I have a device with touch screen LCD and backlight using ep9307 controller of ARM processor. The problem is that we need to completely switch off the backlight so as to make the screen look dead.

Being a newbie in this field, I have no idea how to do that. After studying the schematics and user guide I came to know Brightness control register named as BRIGHT.But I have no idea how to write to that register.

I need to know how to do that. Can anyone please help.

    Hello,
    In order for forum members to be able to help you, you would need to give details on:
    - programming language used,
    - operating system used or bare metal,
    - development environment might also be helpful but not really necessary in this particular case.
    - which steps have you already done, what have you tried and what is the error message if any...
    Kind regards,
    Alban
