I Follow this instruction http://geraintw.blogspot.com/2014/01/rfid-and-raspberry-pi.html.

i run this script on Raspberry Pi B+ (raspbian). when i run 👍

but when i run sudo python setup.py install again :

but when i test with python MFRC522-python/Read.py, cannot detect tag

So think I had the same but after restart it worked like your second attempt.

I just cant get it to run the Read.py

pi@raspberrypi:/gr_programs/RFID/SPI-Py/MFRC522-python $ sudo python read.py
can't open device: No such file or directory
pi@raspberrypi:/gr_programs/RFID/SPI-Py/MFRC522-python $ sudo python Read.py
python: can't open file 'Read.py': [Errno 2] No such file or directory

Looks like a shortfall in my Python understanding but I cant see what Im doing wrong

rey1024,
Do we not need to use the Sudo command to allow us supervisory access to the GOIP pins to be able to read the RFID content?
