Hi everyone,
 
I wanted to share with you a small library I've written to interface with the MFRC522.
 
I needed an RFID reader for a project and, rather uninformedly, ordered a kit with this IC from eBay, similar to this one.
Turns out it wasn't as straightforward as: swipe a tag and some data comes out ;-)
Fortunately, the datasheet is pretty good, and after a lot of reading and googling the ISO14443 standard, I sort of understood how it worked.

Anyway, the library can be found here. It should work properly with the Mifare Classic 1K tags.
It lets you detect tags, select them, read their UID and read and write blocks on the tag.

I hope someone finds it useful!

Michiel

Great! - I've just ported the Arduino project for the same problem, so I'm off now to have a look at how you've implemented it.  :)

You'd be interested that I ended up using an adjusted version of your lib for my Netduino based Maker Faire UK project last weekend. Worked great - thanks.

Oh hey, that's great dotnetworker!

What was the reception like? Any videos of the zoo in action?

Chris,

 

Video -excellent idea, so wrapped up in projects it didn't cross my mind. I'll put something together shortly.
