Pirate 3 Posted June 14, 2021 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 (look on the display's circuit board to see its version) running a Linux-based OS Python 3.5+ Optional: TinkerBoard: gir1.2-gtk-3.0 for the GUI install Installation Clone this repository and install by: $ sudo apt-get install gir1.2-gtk-3.0 $ git clone http://github.com/p1r473/rpi-backlight.git $ cd rpi-backlight $ sudo python3 setup.py install Usage API Example in a Python shell: >>> from rpi_backlight import Backlight >>> >>> backlight = Backlight() >>> backlight.brightness 100 >>> backlight.brightness = 50 >>> backlight.brightness 50 >>> >>> with backlight.fade(duration=1): ... backlight.brightness = 0 ... >>> backlight.fade_duration = 0.5 >>> # subsequent `backlight.brightness = x` will fade 500ms >>> >>> backlight.power True >>> backlight.power = False >>> backlight.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: $ rpi-backlight -b 100 $ rpi-backlight --set-brightness 20 --duration 1.5 $ rpi-backlight --get-brightness 20 $ rpi-backlight --get-power on $ rpi-backlight -p off $ rpi-backlight --get-power off $ rpi-backlight --set-power off :emulator: $ rpi-backlight -p toggle $ rpi-backlight -p toggle -d 1 GUI Open a terminal and run rpi-backlight-gui as root.
