how to change LCD brightness

[PaddleStroke]

Hi,
Using a lime2 with 4.3" LCD, I'm wondering how to change the brightness ? Using the mainline image of Armbian.

Sorry I missed this, my reply at https://www.olimex.com/forum/index.php?topic=7136.0 is still correct. You'd need that device tree overlay configured to the PWM capable pin you use for the backlight.
