ST25R3911B-DISCO firmware supporting UART or I2C?

[MMcAl.1]

Hi,

I have an ST25R3911B-DISCO and have discovered that UART and I2C are not supported on the loaded firmware through searching Google on how to use the interfaces.

I am wondering if there have been any updates in the last two years on this subject.

If there have not been any updates, what is the best way in implementing UART or I2C in conjunction with my external board, the NUCLEO-L552ZE-Q?

As a side note: I am aware there are Nucleo boards that have the ST25R3911B and I2C or that the ST25R3916 has I2C. I have the disco board and am planning on using this with my external processor in any way I can without modifying the board.

Hi MMcAI.1,

please see the older discussion in https://community.st.com/s/question/0D50X00009XkWEXSA3/uart-interface-with-st25r3911bdisco. In short those pins are foreseen but not used by our firmware.
