RFID Reader/Writer


I would like to use a 13.56Mhz RC522 RFID Module (reader/writer module) with XOD. However, I cannot find any hardware node that falls into that category.

Is there already a Library containing this node ?

In alternative how do I create one?

Can someone help ?




I can try something quick with read / write, would you prove it?

ps: here trying, after changing the library, I already have some results


Test library …
It is not finished …
It is not documented …
If you wish you can download and try it, it only works in read mode

Thanks a lot cesars
I am new to Arduino and I am experimenting.
Tomorrow I will get the RFID reader writer and I will test your node :slightly_smiling_face:


new tests :slightly_smiling_face:
