Hi,

Is there any way to switch the LCD screen on and off using the EMX development kit?

Thanks
Edward

You can with little change ont eh board, looking at schematics http://www.ghielectronics.com/downloads/EMX/EMX_DevSys_sch.pdf

You can tap into R14 on the shutdown pin and then use that to shut down the backlight chip or use PWM to dim it.

Gus, this answer was from professional to professional.

Can You explain in more detail which pins to connect (I cannot locate R14 in EMX_DevSys_sch.pdf)? A photo of EMX module with a sketch would be ideal.

Thanks in advance, Roland.

I am afraid that you may damage the board.

Look by the LCD connector. The resistor maybe too small if you are not experienced at soldering.
