Hello Everyone,

I have the same request than ramirez_prieto.valen, I'm looking for an I2C routine in order to write an NDEF message in a M24LR04 tag, but I haven't foud anything about that. Obviously the AN3408 is important for understand NDEF MESSAGE structure, however It's would be very interesting to have an I2C routine. I've tried to write this routine but It seems to be wrong and since 3 days I have tried to debug it.
 I don't know  for example if the CC field his automatically set or if it's defined by the user, furthermore I don't know how to manage user memory area when there is already a previous NDEF message. there are not informations concerning these issues.

An example would be very nice
