    Wiegand Library for HID ProxPoint Plus

    While this library should be able to read any wiegand input, the buffer can only store 64 bits, and it expects there to be less than a 5ms delay between each bit sent.

    Here is a picture of some example wiring:

    To use this library use the following pin attachments

    6005BG00 WireMBED PIN
    data0p30
    data1p29
    holdp28

    include the mbed library with this snippet

    void void onCardRead();
Wiegand rfid(p30, p29, p28, &onCardRead);

int main() {
  while(1) {
    rfid.doEvents(); //checks if data has been fully read, and calls the callback
  }
}

void onCardRead() {
  /*
    Do stuff with data, as we've fully read the card.
    WHen this function exits, RFID reader will be reset to read
    Another Card
  */
}
