Kivy is a multi platform GUI that enables you to create visualizations easily. Kivy comes with a lot of documentation that you can work with fluently after a while.

Install Kivy

Make sure to install Python 3 in the last version that is supported by Kivy. Otherwise will your install fail. Also you will need to work with Python 3 if you want to use Matplotlib in combination with Kivy to avoid a lot of program crashes.

You will have to install some dependencies:

sudo apt install libsdl2-dev libsdl2-image-dev libsdl2-mixer-dev libsdl2-ttf-dev \
   pkg-config libgl1-mesa-dev libgles2-mesa-dev \
   python3-setuptools libgstreamer1.0-dev git-core \
   gstreamer1.0-plugins-{bad,base,good,ugly} \
   gstreamer1.0-{omx,alsa} python3-dev libmtdev-dev \
   xclip xsel libjpeg-dev

Finally Kivy will be installed in a one liner:

python3 -m pip install kivy

After the install this minimal Hello World App will prove your success:

If you are using the Raspberry Pi touch screen you will have to configure accordingly.

Open a terminal and enter the command

sudo nano ~/.kivy/config.ini

then scroll down until you find the section [Input].

Add or modify the follwoing lines:

mouse = mouse

mtdev_%(name)s = probesysfs,provider=mtdev

hid_%(name)s = probesysfs,provider=hidinput 

Now you can start the example.

Next

Start Kivy with Cronjob

If you start Kivy with a Cronjob but you cannot see the window you will have to add the following line in your Cronjob

DISPLAY=:0

Run Kivy in full screen and without menu bar

The config file gives you conrtol over the general behavior of Kivy. Navigate to

/home/user_name/.kivy

Instead of  user_name enter your user name. Often it is pi.

Then open config.ini

Look for fullscreen and borderless. Set the values to 1 and then run your app.
