NFC on RaspberryPi with PN532, py532lib and i2c #piday #raspberrypi @Raspberry_Pi. Is the IRQ pin absolutely required to communicate with the PN532 via I2C? Can the IRQ pin left unconnected? I understand the the PN532 Application Note v1. In addition, it supports RFID reading and writing, and NFC function with Android phone, which makes it quite convenient for wireless connection.
