PN532 Driver

This is still a work in progress driver. At the moment it only supports I2C. For an example check the nfc example.

Datasheet and user manual

• PN532 User Manual
• PN532/C1 data sheet

For implementing the communication the PN532 User Manual is of much more use than the Datasheet.

Reference Driver Code

• Arduino Adafruit-PN532

Reference Hardware

I have tested this driver on a cheap NCF Module V3 board:

This board does not provide the RSTPD_N, this is why I did not have used the reset logic.

For more details please check the manual PN532 NFC RFID Module User Guide

License

Since this is basically a rewrite of the Adafruit Code in Go the license is BSD license as of the original code.
