Creating a Fullscreen Raspberry Pi GUI (HMI) with PySimpleGUI

In this tutorial, we will guide you step by step in creating a fullscreen Raspberry Pi GUI (HMI) using PySimpleGUI. PySimpleGUI is a simple and easy to use Python GUI library that allows you to create desktop applications with minimal effort. With PySimpleGUI, you can quickly create graphical user interfaces for your Raspberry Pi projects.

To get started, make sure you have Python installed on your Raspberry Pi. You can check if Python is installed by running the following command in the terminal:

python --version

If Python is not installed, you can install it by running the following command:

sudo apt-get install python3

Next, you will need to install the PySimpleGUI library. You can do this by running the following command:

pip install PySimpleGUI

Now that you have Python and PySimpleGUI installed, you can start creating your fullscreen GUI. We will create a simple GUI with a single button that displays a message when clicked.

import PySimpleGUI as sg

layout = [[sg.Button('Click me')]]

window = sg.Window('Fullscreen GUI', layout, fullscreen=True)

while True:
    event, values = window.read()

    if event == sg.WIN_CLOSED:
        break

    if event == 'Click me':
        sg.popup('Hello, World!')

window.close()

In this code, we first import the PySimpleGUI library and create a layout with a single button labeled ‘Click me’. We then create a fullscreen window using the sg.Window function with the fullscreen=True parameter.

We then enter a loop where we read events from the window using window.read(). If the event is the window being closed, we break out of the loop and close the window. If the event is the button being clicked, we display a popup message saying ‘Hello, World!’.

Save the code into a file (e.g., fullscreen_gui.py) and run it using the following command:

python fullscreen_gui.py

You should see a fullscreen GUI window with a button that displays a message when clicked.

You can customize the GUI further by adding more elements such as text boxes, sliders, checkboxes, etc., and by defining more complex layouts. PySimpleGUI provides a wide range of elements that you can use to create rich and interactive GUIs for your Raspberry Pi projects.

By following this tutorial, you can easily create a fullscreen Raspberry Pi GUI using PySimpleGUI and enhance the user interface of your projects. Feel free to explore the PySimpleGUI documentation for more advanced features and customization options.
