Yesterday I bought the famous RC552 RFID read/write module to use with my Raspberry Pi 2B (I've also got an Arduino in the mail right now) and I've been trying to get it to work but I just can't. I started by installing
python-dev. I then installed SPI-PY by downloading it from GitHub (
https://github.com/lthiery/SPI-Py) and used
sudo python setup.py install to install it.
I then connected the module to my Pi using this diagram:
Then, I downloaded this library from GitHub (
https://github.com/mxgxw/MFRC522-python) and ran the
Read.py example application to try it out. Upon doing so, I got the following message:
can't open device: no such file or directory. The program then halted. I tested to see if it was a line of code causing the problem, by placing the command
print "Test" at the top of the document. I saw the following:
can't open device: no such file or directory
I definitely know it's something in the code now. I moved my print command down the document, until it was under this line:
MIFAREReader = MFRC522.MFRC522()
Once it was under this, I only saw the error message. So I know it's this line.
I decided to try a different project, so I downloaded this one (
https://github.com/ondryaso/pi-rc522). I ran the
Read.py, but got the same message.
What's going on? Did I do something wrong? Your help would be greatly appreciated.
Apologies for putting the links as code, the editor said I couldn't post more than 2 links because my rep is below 10.
