Hi,

I'm looking for the circuit diagram for the adaptor board for the 7" LCD.

Accodring to the LCD datasheet the LCD supports dimming. I need to find out
to which pin this is connected, if it is connectged at all.

Also, does the FET on the LCD board power off the whole LCD?

Thank you,
Errol

Wow, I got a reply.

GPB1 can be connected to the LCD's dimming control.

To do that though R12 must be removed and R13 installed.

But doing this before configuring GPB1 will leave you with a blank LCD.

Will investigate drivers this weekend to control backlight.

Thanks,
Errol

Why didn't you write in my question
(http://www.friendlyarm.net/forum/topic/401?lang=en) of previous week?
My question was nevertheless exactly the same.
