I am trying to get a RC522 to work with python3, running this test I get this error

  File "MFRC522_test.py", line 25, in <module>
    val = spi.transfer((((addr<<1)&0x7E) | 0x80,0))
TypeError: function takes exactly 2 arguments (1 given)

Checking out SPI-Py to 8cce26 fixes the issue

The SPI-Py API changed. I've updated the MFRC522_test.py .gist to work with the current version.
