Topic: NFC chip and Microcontroller

hi all,

I'm new for this forum. I'm a university student, and for my final year project is based on nfc.
I have done a software application to write and read data for MiFare card by ACR 122U as a part of my project by java and succeeded there.:-)

Now as a second step i want to develop a stand alone NFC door controller.For this I need NFC chip and Micro controller i guess. As far as i read earlier discussion in this forum, i think PN532 will be better for my use. I have some boubts, please clarify me.

1. Is PN532 will be a good choice for the above application?
2. What Micro controller can i use for this purpose, where i need to connect the NFC Chip (PN532)?
3. can anyone explain me the basic steps i should follow in order to this?
4. Does anyone have schematic diagram which connects NFC chip and micro controller?
5. Can anyone suggest me the places where i can buy the NFC chips?
6. Is there any other alternative way other than connecting PN532 to micro controller for building a stand alone door controller?

I'm in the initial stages of project, don't know what i should do, and what is the best path. So Please help me, even though it sound like very easy questions.:-)

Yes.

Depends on needs, if you want to made a simple access control (eg. based on tag's UID) a little 8bits microcontroller like Arduino board, you could also use a Cortex-M3 (almost the same price) which is a 32bits microcontroller with a higher clock speed which offers more possibilities.

Simply connect a PN532 breakout board on MCU's UART.

PN532 breakout board: http://www.adafruit.com/products/364
Arduino series: http://www.adafruit.com/category/17
Cortex M3: http://www.adafruit.com/products/281

I hope it helps.

Re: NFC chip and Microcontroller

Thank you for the reply :-)

Unfortunately PN532 breakout board is not in stock currently. Is there any other boards with PN532 which gives the similar functionality?

And some more clarifications I needed.
1. can i go with PN532 without the breakout board?
2. if so, how can i get the antenna?

Thank you. :-)

Re: NFC chip and Microcontroller

Make HF Antenna is not a simple task at all... I think you should use an already antenna and PN532 equipped board.

hi sssinthu,
  I am also a fresh developer for nfc, could you please tell me how to get t o start to develop nfc application?
