Nucleo NFC06A1 Capacitive Sensor Example

Hello,

I try to get a feeling for the possible features and use cases of the ST25R3916 NFC Reader chip.

One point which sounds very interresting is the capacitive measurement.

Are there any code examples (as the linux driver for the ST25R3916) available or can someone share the basic commands to test the feature (NFC read/write is already working).

Best regards,

Sebastian

    Hi Sebastian,

    Some of our demos are showcasing the inductive wake-up. If you look at the code it will be a matter of a few changes to the rfalNfcDiscoverParam struct to enable the capacitive wake-up instead of the inductive one. Best to start here with the polling demo inside the ST25 Embedded NFC lib.

    Maybe more convenient to investigate would be the ST25R3916-DISCO where you will find a PC GUI which allows you to see a graph of the measured values which may be helpful in investigating about the characteristics of such a system.

    Best Regards, Ulysses
