STEVAL-25R200SA Custom application development.

sreevishakk · ‎2025-06-06

Hi Team,

I have purchased the STEVAL-25R200SA board. I would like to know if I can develop custom NFC features using this board. And please provide me with sample NFC application code suitable for this board to refer to.

Thank you

See the Product Page for Documentation and supporting Tools & Software; Schematics, etc, are on the CAD Resources tab.

See also https://www.st.com/en/nfc/st25-nfc-readers.html? for general information & resources for the ST25 family

And the Product Page for the specific ST25R200 device: https://www.st.com/en/nfc/st25r200.html

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

Hi Andrew Neil,

Thank you for your prompt replay,

I could not find any sample NFC application code from the links. Can you please help me to get it?

Look on the Tools & Software tabs of both the Kit and the chip Prudct Pages.

Hi,

the STEVAL-25R200SA runs a FW (sources available in STSW-ST25R020) and is controlled by a PC GUI (available in STSW-ST25R019) over the STLink Virtual Communication Port. The PC GUI includes a Reader+Tag demo tab that can be used to run the STEVAL-25R200SA in standalone mode and to react on some events (e.g. switch on a LED when a tag is detected). This can be used to prototype embedded custom applications. See the related User Manual UM3364 (ST25R200 Eval GUI for the STEVAL-25R200SA kit). Custom applications can also be developed on PC side over the serial link API. Feel free to provide more information about your custom application.
