Yet Another Arduino Wiegand Library

 

 

#define PIN_D0 D1
#define PIN_D1 D2

// The object that handles the wiegand protocol
Wiegand wiegand;

// Initialize Wiegand reader

Serial.println("Start...");

//Install listeners and initialize Wiegand reader
wiegand.onReceive(receivedData, "Card readed: ");

wiegand.begin(WIEGAND_LENGTH_AUTO);

//initialize pins as INPUT
pinMode(PIN_D0, INPUT);

// Continuously checks for pending messages and polls updates from the wiegand inputs
