rc522 0.0.1.5

RFID Utility

Context

This tool is showcased in the project IotaWorkshop

Summary

This is a basic RFID libarary for the rc522. This simply lets you pull a single tag data and later lets you confirm it using the function detectKey(uid,block)

Installation

This package requires RPi.GPIO, which I installed on arch arm using

yay -S python-raspberry-gpio

But ubuntu or rasbian can use,

pip install RPi.GPIO

To install pibeep simply install the pip package.

pip install rc522

Example

Simple example of usage

from rc522 import detect,detectKey
uid,block detect(rst=31,irq=29)
#Later you can check that the same raid tag is still there using
if detectKey(uid,block,rst=31,irq=29):
	print("RFID tag is still there")
else:
	print("RFID tag is vacant!")

Wiring

To connect the RC522 module to SPI use the following schematic. Use this pinout diagram for reference.
