No MIFARE Ultralight support #5

Hi,

So far, a really nice program you wrote!

However, I want to use RFID stickers instead of cards, which don't seem to work with your code. I would constantly get the error: PCD_Authenticate() failed: Timeout in communication. Could you add support for writing to MIFARE Ultralight (C)?

Looks like the problem is the MFRC522..

According to this: http://ham.marsik.org/2017/04/using-cheap-rc522-nfc-reader-to-read.html , you should be able to read the Ultralight C if you change two inductors on the PCB.

Thanks for the quick response!

I took a look at the link you send my, but my MFRC522 is able to read the Ultralight (as I also tested with the DumpInfo from the MFRC522 library).

This error only occurs when trying to write the song number data...
