Python library containing some functions to control the 7" touch display from the Raspberry Pi foundation.

Python library containing some functions to control the 7” touch display from the Raspberry Pi foundation.

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 brigntness smoothly or abrupt

• Set the display power on or off

• Get the current brightness

• Get the maximum brightness

Installation

• Install from PyPI using pip install rpi_backlight, or

• clone this repository and python setup.py install.

Usage

Example in a Python shell:

>>> import rpi_backlight as bl
>>> bl.set_brightness(20, smooth=True)
>>> bl.set_brightness(255, smooth=True)
>>> bl.set_brightness(20, smooth=False)
>>> bl.max_brightness
255
>>> bl.current_brightness
20
>>> bl.set_power(False)

NOTE: Code using 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

• 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!
