rpi-backlight- Control Raspberry Pi 7" Screen Backlight with Asus TinkerBoard
Big Grin 
Hi all,
I have modified the Github Python Project "rpi-backlight" to work with the Asus Tinkerboard

A Python module for controlling power and brightness of the official Raspberry Pi 7" touch display.

[Image: example.gif]
Change the display brightness smoothly or abrupt
Set the display power on or off
Toggle the display power on and off
Get the current brightness
Get the maximum brightness
Get the display power state (on/off)
Command line interface
Graphical user interface


A TinkerBoard including a correctly assembled 7" touch display v1.1 or higher (look on the display's circuit board to see its version) running a Linux-based OS
Python 3.5+
Optional: TinkerBoard: gir1.2-gtk-3.0 for the GUI install

Clone this repository and install by:

$ sudo apt-get install gir1.2-gtk-3.0
$ git clone
$ cd rpi-backlight
$ sudo python3 install


Example in a Python shell:

>>> from rpi_backlight import Backlight
>>> backlight = Backlight()
>>> backlight.brightness
>>> backlight.brightness = 50
>>> backlight.brightness
>>> with backlight.fade(duration=1):
...     backlight.brightness = 0
>>> backlight.fade_duration = 0.5
>>> # subsequent `backlight.brightness = x` will fade 500ms
>>> backlight.power
>>> backlight.power = False
>>> backlight.power

NOTE: Code using set_ functions of this library has to be run as root, e.g. sudo python , if the permissions for changing the backlight were not changed as described in the installation section!

Open a terminal and run rpi-backlight as root:

$ rpi-backlight -b 100
$ rpi-backlight --set-brightness 20 --duration 1.5
$ rpi-backlight --get-brightness
$ rpi-backlight --get-power
$ rpi-backlight -p off
$ rpi-backlight --get-power
$ rpi-backlight --set-power off :emulator:


Open a terminal and run rpi-backlight-gui as root.

Thanks for the recognition
I will add a screenshot and links to the Github of it working when I hit the 25 post limit
