rpi-backlight 1.3.0

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

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

WARNING: This comes with absolutely no warranty, do anything on your own risk!

The code is very small and simple, but will be extended in the future for new features. Feel free to contribute!

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

Installation

• Install from PyPI using pip install rpi_backlight, or

• clone this repository and python setup.py install.

Usage

Start from the command line:

• rpi-backlight for a CLI

• rpi-backlight-gui for a GUI (experimental)

Example in a Python shell:

>>> import rpi_backlight as bl
>>> bl.set_brightness(20)
>>> bl.set_brightness(255)
>>> bl.set_brightness(20, smooth=False)
>>> bl.get_max_brightness()
255
>>> bl.get_current_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 !

Requirements

• A Raspberry Pi including a correctly assembled 7” touch display v1.1 or higher

• Python 2 or 3

Todo

• Allow to set the brightness fading duration in set_brightness(value)

• Create a really simple GUI in pygobject to change the display brightness, maybe just a scale/slider

I would be happy if you can help shortening this todo-list!
