A micropython library for using Wiegand RFID / NFC card readers on ESP32 devices.
Download the uwiegand folder and upload it to your micropython board. You can download this entire repository here.
Using the default UART config (machine.UART(1, baudrate=9600, timeout=2, timeout_char=10, tx=19, rx=18)).
import uwiegand
wiegand_pin_zero = 19
wiegand_pin_one = 18
rfid_reader = uwiegand.Wiegand(
wiegand_pin_zero,
wiegand_pin_one,
uid_32bit_mode=True,
timer_id=0,
)
# note that this is not blocking and needs to be called as often as possible to check for new card scans
card_id = rfid_reader.read_card()You can also add this repo as a git sub module to your project to make keeping it up to date easier.
