urdm6300 is a simple micro python driver / library that allows you to read RFID cards from an attached RDM6300 board. Several suppliers manufacture these boards, including seeed studio and various Aliexpress sellers.
Simply download the urdm6300 folder and upload it to your micro python 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)).
from urdm6300 import Rdm6300
rfid_reader = Rfid()
# 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 specify your own UART object if you'd like:
from urdm6300 import Rdm6300
import machine
uart = machine.UART(1, baudrate=9600)
rfid_reader = Rfid(uart)
# 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.
