Dear all,

Has anyone ported or made available a driver for the common used mifare reader that uses the mrfd522 nxp chip?

That is very easy to check. If you look closely at this forum's header, you will see three dark tabs near the left side: "FAQ", "Search", "Members" and "The team". Clicking on the "Search" one will bring you to a search screen, where you can type the name of the chip in the search query, and see if anyone ever mentioned it here. I hope that helps (and no, I'm not trying to belittle you or act like a smartass, that link is a bit hard to see and it's not immediately obvious it's the best way to check, so I understand that you asked instead).

Here is a port I did a while a go. Tested so far on ESP and WiPy.

Dear all,

With a little search I found some code that was *almost* ready to be used. I hooked up the RC522 to the PYB board and adapted the code for it to work. So if you are in the need to attach a RFiD/NFC reader with the MFRC522 chip you can get the code from github.com/rolandvs/mycropython-nfc.

Regards,

Roland

Thanks for the post. I look into it. Using the same reference code for the MFRC522 I managed to get it working with the PYB board. However trying to get it to work with the current mpy1.8.2 on the ESP13 gives memory problems. Yours is smaller so I will give it a go. Thanks.
