It fixes the errors but i cant get any readings -> card aren't detected but maybe someone can tell me why

Daniel2193 commented 4 years ago

Just found the solution that worked for me

git clone https://github.com/lthiery/SPI-Py.git cd SPI-Py git checkout -b 8cce26b9ee6e69eb041e9d5665944b88688fca68 sudo python setup.py install

After that Enable Remote-GPIO for raspberry pi interface.

worked with python3 and 2 on Pi 4
