Topic: Libnfc + libnfc_llcp + UC3C µC + Arygon APDB Reader UART && Nexus S

Hi,
i am new to this forum. This is my firtst post.

I want to exchange data (peer-to-peer) between AVR 32-bit AT32UC3C0512C micrcontroller and Google smartphone Nexus S.

On the one side i have an evaluation kit AT32UC3C-EK connected over (high speed)UART with Arygon APDB OEM Reader (v1.2 µC equiped and with PN532) and on the other side Nexus S.
Dev environment is Win7, AvrStudio 5.0 + ASF, Eclipse + ADT.

I can now access reader over UART and i have an app on the Phone to exchage data with it.

My problem is to implement the communication stack on Atmel µC including NFCIP, MAC, LLCP and NPP at the top.

The questions are:
Is it better to adapt libnfc for my purposes or to write it from scratch?
Is there already someone, who did this work?
Can somebody give me a hint where to start?

Thank you in advance.

There is already a WIP library : libnfc-llcp that implements LLCP on top of libnfc.
The libnfc-llcp package also provides NPP example named nexus-get-tag example.
