sudo apt install git python-dev -y
Now we have to install SPI-Py using the folowing commands:
cd ~
git clone https://github.com/lthiery/SPI-Py.git
cd SPI-Py/
sudo python setup.py install
Install MFRC522-python
Almost done, just a few commands left to install this package:
cd ~
git clone https://github.com/tsndr/MFRC522-python.git
