rpi-backlight- Control Raspberry Pi 7" Screen Backlight with Asus TinkerBoard
#1
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.

Features
Change the display brightness smoothly or abrupt
Set the display power on or off
Get the current brightness
Get the maximum brightness
Get the display power state (on/off)
Command line interface
Graphical user interface

Requirements
A Raspberry Pi including a correctly assembled 7" touch display v1.1 or higher running a Linux-based OS
Python 2 or 3
gir1.2-gtk-3.0 for the GUI, install via sudo apt-get install gir1.2-gtk-3.0

Installation
Install from PyPI using:

clone this repository and install by:

Code:
git clone hxxp://github.com/p1r473/rpi-backlight.git
cd rpi-backlight
sudo python3 setup.py install


Usage

API
Example in a Python shell:


Code:
>>> import rpi_backlight as bl
>>> bl.set_brightness(255)
>>> bl.set_brightness(20, smooth=True, duration=3)
>>> bl.get_max_brightness()
255
>>> bl.get_actual_brightness()
20
>>> bl.get_power()
True
>>> bl.set_power(False)

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

CLI
Open a terminal and run rpi-backlight as root:

Code:
$ rpi-backlight -b 255
$ rpi-backlight -b 20 -s -d 3
$ rpi-backlight --max-brightness
255
$ rpi-backlight --actual-brightness
20
$ rpi-backlight --power
True
$ rpi-backlight --off

GUI

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