CoreMP135 screen saver sleep for built in LCD

[mgrouch]

Is there a way to enable sleep for built in LCD to
turn it off to conserve power and turn on/wake up by touch?

I’m using Debian image.

Thanks

I do not see how. There are examples for displaying things on ILI9342C
using framebuffer and LVGL.
I do not see how to turn off backlight on ILI9342C. Is there some code example? Or command line utility with the code to control brightness? I was able to code that on m5stack tough on esp32 which has same ILI9342C.

Also how to wake up screen by touch?
I guess with brightness off touch functions are still there. So I need example of code listening for touch event and controlling backlight (voltage of it?) on ILI9342C.

I need some help.
Thanks
