Introduction¶
When I bought the official Raspberry Pi 7” touch LCD, I was quite happy about it - with one exception: you can’t change the display brightness in a simple way out of the box.
I did some research and hacked some Python code together. Time passed by,
and the whole project turned into a Python module: rpi-backlight
.
Currently it has the following 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
Now you are able to easily set the brightness of your display from the command line, a GUI and even Python code!
