Raspberry Pi 7" LCD emulator for rpi-backlight

Project description

Raspberry Pi 7" LCD emulator for rpi-backlight

License PyPI Black Issues

Demo

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.

Requirements

Python 3.5+ is required, along with the packages PySide2, watchdog and rpi-backlight>=2.0.0b5 (see below).

Installation

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>=2.0.0b5
$ pip3 install --no-deps rpi-backlight-emulator

Usage

Run:

$ rpi-backlight-emulator

Next, open a Python shell and create a rpi_backlight.Backlight instance using the emulator:

>>> 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.

Enable Show live screen to replace the static Raspbian Buster screenshot with a live preview of your monitor.
