RFC522 RFID Reader

[biktoe]

Hi all,

Could someone point me in the right direction for the control of the RFC522 RFID reader/writer in JAVA? 99.9% of the times Google is my friend, but it has let me down in this case.
I'm already using Pi4J, but struggle to find proper examples for this hardware. All ready-made libraries/examples are in Python, a language which I despise

Any help would be appreciated!

Regards,
Bik

Probably not much resources in Java for a device meant for Arduinos.
Most likely you would have to re-engineer the code yourself based on some previous implementations.

MFRC522 is not made for Arduino - it is general purpose chip which on this board was configured to use SPI interface (if I got it right - at least by https://www.addicore.com/v/vspfiles/dow ... tGuide.pdf or https://community.particle.io/t/getting ... ed/3571/97).

Read documentation (for instance here: http://www.nxp.com/documents/data_sheet/MFRC522.pdf) and get the commands you need to send it for it to work (read/write data of it).

Pi4j (http://pi4j.com/) provides low level SPI interface (sorry - it seems that I am one of those who say LED diode O: ) and you can take it from there. Here is example file: https://github.com/Pi4J/pi4j/blob/maste ... ample.java

I've just ordered one of these off ebay and will be adding support for it in my diozero Java library.

Hello guys,

I know this thread is old but I made my own interface for Java. I followed the instructions on this site:

In addition, I created the following API for Java:

Nice. I should have updated this thread, I ported the Arduino library to Java last year, code here: https://github.com/mattjlewis/diozero/b ... RC522.java
