Compatibilidad con teclado wiegand.

[sistemasyusa]

Buen día hasta el momento me funciona bien la tarjeta estoy emocionado por las ventajas que ofrece , pero me gustaría saber si puede ser compatible con algún teclado wiegand, ví la publicación que tienen con otra tarjeta pero no me funciona , alguna librería para usarla con esta tarjeta y en qué puerto  

GRACIAS

see top GREEN terminal IO1 and IO2 , these two pins can use for Wiegand device.

Muchas gracias, voy a conectar esos dos pines pero me refería a que código cargar en Arduino ide para poder leer las teclas desde teclado wiegand, agradezco de ante mano. Buen día

Creo que ya encontré la librería , y funciona excelente , gracias

* This program demonstrates how to read Wiegand data (commonly used in RFID readers) using GPIO pins.
* It is configured for Wiegand 26-bit and 34-bit formats.
