Xmega128A1 and Mikroe RFID reader(EM4095)

[Lalith]

Hello,

 

   I want to interface xmega128a1 board and rfid reader.

1.How do I connect it .

    EM4095 PIN:

    OUT  RDY/CLK

    SHD   MOD

    NC    NC

    NC   NC

    VCC  GND

     

    XMEGA Pins:

  SDA  SCL

  RXD  TXD

  SS      MOSI

  MISO  SCK

  GND    VCC

 

I have used jumper wires to connect VCC – VCC,  GND-GND,  OUT-RXD, RDY/CLK-TXD, not sure of SHD and MOD.

 

2. Which is better – Interrupt reading or Polled reading?

 

Can anyone give a example how to program this?

 

Thank you
