How to switch off the fez-disp expansion


#1

Hi Guys,

do you know how to switch off the fez-disp expansion backlight? I tried with

SendCommand(0xAE);

but it seems not to be the right command!

Thank you for your help!

What fez-disp expansion are you talking about?

The back-light is connected to a jumper with power to make it switchable, you need to add a transistor to control it.

Gus, are you referring to JP1?
