Few days ago we had a great discussion on twitter: https://twitter.com/MironixGaming/statu ... 2555484161 What we've established: - There's no way to control backlight on the go, the gpio controlling the display is assigned to kernel at boot. The question are: - Is there a way to boot the device with display backlight off? - Can we do a hardware hack to switch the backlight on and off (page 11 of the schematic shows a pin on LVDS as BL_ON)
Hi, i suppose you can try to cut the relative signal cable with a switch. BL_ON activate the blacklight when the signal is high, so disconnecting it should be turn off the light. I also suppose that you can control the backlight from another gpio connected to the board. I never tested it. i'll try as son as possible.
