Installation of the soware
Should you already have the latest Raspbian system on your Raspberry
Pi, you can skip this step and you can continue with the next step.
Install on your SD card the latest Raspbian with the help of the Win32-
Disk-Imager which you can find with the following link.
Installation of the libraries
In order to enable you to use the display as quickly and easily as possible,
we use a library from Adafruit, which was published under the MIT licen-
se. To do this, open the console and execute the following commands:
sudo apt-get install git
git clone https://github.com/adafruit/Adafruit_Nokia_LCD.git
cd Adafruit_Nokia_LCD
sudo python setup.py install
Use of the code examples
The installation of the display is now completed. Open now the folder of
the library which includes the code examples, with the following
command:
cd examples
Now you can test dierent code examples on your display. You can of
course modify these examples aer your wishes and desires.
sudo python animate.py
sudo python image.py
sudo python shapes.py
