Raspberry Pi 7" LCD emulator for rpi-backlight
Raspberry Pi 7" LCD emulator for
This is an emulator for the Raspberry Pi 7" LCD to test and develop
rpi-backlight without having a physical
display connected or even running on the Pi.
PySide2 wheels for x86/x64 are available on PyPI, so you can simply run:
$ pip3 install rpi-backlight-emulator
On ARM (e.g. Raspberry Pi) it's more complicated (and only the new Debian/Raspbian Buster will work, Stretch won't - you'd have to install PySide2 from source):
$ sudo apt install python3-pyside2.qtcore python3-pyside2.qtgui python3-pyside2.qtwidgets $ pip3 install watchdog rpi-backlight>=2.0.0 $ pip3 install --no-deps rpi-backlight-emulator
Note: on Windows, you'll need administrator privileges to create symbolic links, which this program does - so you'll have to execute the above as administrator.
Next, open a Python shell and create a
rpi_backlight.Backlight instance using the
>>> from rpi_backlight import Backlight >>> backlight = Backlight(":emulator:") >>>
Now, continue like you're connected to a real display!
You can make changes to the display using the emulator, they'll be reflected in the Python-API and vice versa.
Show live screen to replace the static Raspbian Buster screenshot with a live
preview of your monitor.
