# Wiegand protocol reader for micropython

This library is essentially the Wiegand class, which allows the user to set

callbacks based on receiving a card number from a 

[wiegand-protocol](https://en.wikipedia.org/wiki/Wiegand_interface) reader.

## Example usage:

```python

    from wiegand import Wiegand

    VALID_FACILITY_CODES = [ '123']

    VALID_CARDS = [ '12345' ]

    GREEN_LED = Pin(...)

    RED_LED = Pin(...)

    WIEGAND_ZERO = XX  # Pin number here

    WIEGAND_ONE = YY   # Pin number here

    def on_card(card_number, facility_code, cards_read):

	if (card_number in VALID_CARDS) and (facility_code in VALID_FACILITY_CODES):

	    GREEN_LED.high()

	    RED_LED.low()

	else:

	    RED_LED.high()

	    GREEN_LED.low()

    

    

    Wiegand(WIEGAND_ZERO, WIEGAND_ONE, on_card)

```
