Probably you need:
to develop a driver in Python for the PN532
from adafruit_pn532.i2c import PN532_I2C
import nfc
import ndef
A suggestion for an experiment with PN532:
Be aware of the I2C clock stretching issues of the pn532, see the data sheet and adafruit
If the I2C bus supports clock stretching, you don't'need req=req_pin, irq=irq_pin,I was using a FT232H USB to I2C with GPIO ports for experimenting with the PN532.
