Hello,

If you have an Arduino in front of PN532, you can make a firmware for Arduino that handle UART (or serial over USB) just like the PN532 do when its connected directly to a UART->USB dongle.
There is no need for additional driver in libnfc in this case.

Its not possible to compile libnfc for Arduino.

Arduino do have a different code to forward instructions send from PC (by libnfc) to the connected PN532.
