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

[p1r473]

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
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

Requirements
A Tinkerboard 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 http://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
$ rpi-backlight --on
$ rpi-backlight --toggle

GUI

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

Big praise for your job. I wish you (or someone else) to add these bits to the wiki pages.

Thanks for the recognition

I will add a screenshot and links to the Github of it working when I hit the 25 post limit
Which wiki are you speaking of?
