How can I use M24SR64-Y to read data from or write data on MifareClassic (NDEF Formatable) Tag?

[OElzi]

I am using STM32F401RE and M24SR64-Y to read data from or write data on Mifare tags, and I have some questions, Can I use X-CUBE-NFC4 software with M24SR64-Y ? , as on your site the only compatible software is X-CUBE-NFC1.

So, please can you explain to me how can I use M24SR64-Y to read data from or write data on MifareClassic (NDEF Formatable) Tag?

Also how can I change st.com in the code?

i changed st.com into facebook.com

 /* Prepare URI NDEF message content */

 strcpy( URI.protocol,URI_ID_0x01_STRING );

 strcpy( URI.URI_Message,"facebook.com" );

 strcpy( URI.Information,"\0" );

and the output doesn't change from st.com to facebook.com !!

I replaced all "st" in the code with "facebook" and again the output doesn't change.

Do you have any idea how is that possible to write "st.com" on the tag while there isn't any "st" in the code?!!!!

HI,

if you want to read/write data from/to a tag through the RF interface, you need to use a tag reader such as:

• ST25R95
• ST25R3911B
• ST25R3916

M24SR64-Y is dynamics Type 4 tag (i.e. tag having a RF interface and a I2C interface). The X-CUBE-NFC1 is used to write data on this tag through the I2C interface. This cannot be used to read/write data through the RF interface on other tags and therefore this is not suitable for your purpose.
