Hello,

I have it working on a Arduino with ST25DVK, know ihave trouble switching from a ST25DVK to a ST25DVKC, I can see the i2c is never established, I was wondering since the ST25DVKC has a configurable slave-adr, that I then have to set it myself.

    Hello,

    The ST25DVKC has indeed configurable I2C slave address.

    But factory setting for slave address is the same one as ST25DVK.

    So if you have not modify it by yourself, it should still have the same slave address as a ST25DVK.

    For your information, there is an application note on ST web site explaining in details how to migrate from ST25DVK to ST25DVKC, here:
