EMX - Turn LCD On/Off?


#1

Hi all!

I’m sure this has been asked before but I can’t seem to locate a definitive answer. A requirement for my application is that it should turn the LCD off after a period of inactivity, and then turn it back on when the screen is touched.

Any help/advice/links are appreciated!

You could set a white/black screen and power off the backlight until the touch is pressed. (Is this on FEZ Cobra?)

Yes sorry it is a FEZ Cobra. Either turning the whole LCD off or the backlight would be sufficient I think.


#4

FEZ Cobra does not have an I/O pin assigned for the LCD backlight so this would need some hardware tweaks.


#5

There is backlight shutdown pin on the LCD panel, you need to wire it to any free IO on cobra mainboard.

Thanks for the comments, Gus I will have to get my electrical eng’s to look at this.
