None that I'm aware of. You need to turn off blanking, and maybe control blanking/backlight yourself.The only "problem" I have is that when console goes blank, if I touch the panel it doesn't resume. Since I've neither the keyboard nor the mouse attached to my Pi, I need to "resume" my display touching it.
Is there a way to do it?
See here: https://github.com/notro/fbtft-spindle/ ... e#blanking
If you're using X windows, some details: https://github.com/notro/fbtft-spindle/ ... -backlight
You could perhaps implement backlight control by listening to /dev/input/touchscreen and reset a timer every time an event comes, and then when the timer fires you can turn off backlight. So when the next event comes in and backlight is off, you can turn it on.
If you know python, this might be a starting point: https://pythonhosted.org/evdev/tutorial.html
Let me know if you find a solution to control backlight this way.
