How to configure the ST25R3916 in Card emulation mode.

[ASinh.2]

Hi Experts,

Has anybody tried configuring the ST25R3916 in Card Emulation mode using external MCU using SPI bus ? I was looking for what register/s need/s modifications ?

Thank you for the help in advance.

regards.

Hi ASinh.2,

ST provides different SW packages with examples that demonstrate the Card Emulation feature. in particular, 2 demos are available in ST25 Embedded NFC library:

• ST25NFC_Embedded_Lib_ST25R3916\Projects\STM32L476RG-Nucleo\Applications\X-NUCLEO-NFC06A1\polling contains an example of pooling loop that alternates between Reader/Writer mode and Card Emulation mode
• ST25NFC_Embedded_Lib_ST25R3916\Projects\STM32L476RG-Nucleo\Applications\X-NUCLEO-NFC06A1\bluetooth_pairing contains an example of Card Emulation. The ST25R3916 is used to emulate a tag having an NDEF Bluetooth pairing record.

The examples are ready to run on NUCLEO-L476RG (STM32 MCU board) + X-NUCLEO-NFC06A1 (ST25R3916 expansion board) and can be easily ported to other MCU.

I would recommend to use the ST25 Embedded NFC library for your application.
